TE AMPMODU 2.54 mm Headers and AMP-Latch IDC Cable 2026

Why the 2.54 mm signal header is suddenly a Q3 2026 story again

For two decades the 0.100" (2.54 mm) pitch board-to-board header has been the kind of part you reach for without thinking: a TE Connectivity AMPMODU Mod II breakaway on a PLC backplane, an AMP-Latch shrouded header carrying an IDC ribbon to a sensor breakout, a BergStik / Dubox unshrouded strip on a card-edge I/O daughtercard. The catalog depth at independent distributors reflects that — the catalog here carries the TE AMPMODU Mod II 9-position through 39-position variants (9-103323-0-09, 9-103323-0-39), the 36-position dual-row 4-103322-0-18, the right-angle gold-plated 2-826631-4, plus the AMP-Latch shrouded 499582-8 and 1-102155-2 — alongside the FCI legacy BergCon 76314-111LF, Dubox 89882-340LF, and BERGSTIK II 69190-109HLF and 92417-224HLF. Those references are not rarities; they are stock items across hundreds of industrial, telecom, and AI-server backplane designs.

The reason this family is back on a buyer's desk in Q3 2026 is not nostalgia. The combination of a tightening PCB supply backdrop, the copper-cost pass-through that has run through 2025 and into 2026, and a wave of industrial automation retrofits and telecom ATCA/AMC refresh cycles has turned what used to be a stocking-class part into a quoted-class part on certain position counts and platings. We are seeing lead-time extensions, allocation on the gold-mating variants, and tighter replenishment cycles on the IDC ribbon-cable headers than we did in any quarter of 2024 or 2025. This guide explains how we read the supply picture from the buyer's side, what cross-references actually work (and which do not), and where the catalog depth gives an independent channel a real sourcing window.

What is happening in the PCB and raw-material backdrop

Electronics Weekly reported in mid-August 2026 that the PCB shortage is getting worse, not better — a continuation of the upstream constraint that began with copper and resin cost pass-through in 2025 and was amplified by the 2026 AI server build-out. The connector side does not move in lockstep with the board side, but the interaction is direct: a board that takes six to eight weeks instead of three changes the way a buyer sequences header orders, because the headers have to land before the boards clear the EMS line, not after.

Copper remains the dominant variable. Reuters and Discovery Alert tracked the run that took LME copper through record highs in mid-2026 as AI data-center demand pulled against constrained mine supply. The TE Connectivity Q3 FY26 earnings call on July 22, 2026 — 14% sales growth, 19% EPS growth above guidance — acknowledged both the raw-material pressure and the demand pull from data-center and industrial customers. Independent distributors see this as a real, but uneven, signal: the 3 A tin-plated signal-header side of the AMPMODU line moves on allocation in bursts, while the 5 A gold-plated variants and the AMP-Latch shrouded headers carry longer factory lead-times regardless of the macro environment.

On the industrial demand side, the Hannover Fair 2026 (May 7, 2026) framed industrial AI and electrification as the year's defining themes, which historically translates into a refresh of PLC I/O modules, distributed I/O blocks, and motor-starter wiring — all of which sit on 2.54 mm headers in some part of their signal path. ATCA/AMC telecom refresh and AI-server backplane signal paths (especially in the management and telemetry layers) continue to drive demand for the dual-row, higher-position-count members of the AMPMODU and AMP-Latch line.

The TE Connectivity AMPMODU Mod II 2.54 mm breakaway header family

The AMPMODU Mod II line is the workhorse 0.100" (2.54 mm) pitch board-to-board and board-to-cable breakaway header from TE Connectivity AMP Connectors. The Mod II designation refers to the square 0.025" male pin geometry, the unshrouded breakaway construction that lets the buyer snap off any position count from a continuous strip, and the through-hole solder or through-hole right-angle termination that suits standard 0.062" to 0.125" PCB thicknesses.

The catalog depth matters here because the same base product (the 103323, 103322, 103327, and 826631 base numbers) covers position counts from 2 to 50 in single-row and dual-row variants, with both tin and gold mating contact finishes, and with both vertical and right-angle through-hole mountings. A few reference points from the catalog:

TE Connectivity 9-103323-0-09 (AMPMODU Mod II, 9 positions, single row, 0.100" pitch, through-hole right-angle, tin mating and post, UL94 V-0, -65°C to 105°C, 3 A) — the baseline 9-position member used on PLC I/O termination boards and on sensor-breakout signal headers.
TE Connectivity 9-103323-0-39 (AMPMODU Mod II, 39 positions, single row, right-angle, tin, 3 A) — the 39-position member used where the signal count is high but the row-count constraint is one — typical on the back of a 1U industrial controller or a low-density telemetry board.
TE Connectivity 4-103322-0-18 (AMPMODU Mod II, 36 positions, dual row, through-hole, tin-lead, 3 A) — the dual-row variant that gives 36 signals in a 0.100" x 0.100" footprint; this is the position density that makes the AMPMODU line competitive with smaller-pitch mezzanine options when the signal integrity budget allows it.
TE Connectivity 4-103327-0-09 (AMPMODU Mod II, 9 positions, single row, through-hole, tin-lead, 3 A, 0.230" mating length) — the vertical-mount counterpart to the right-angle 9-103323-0-09; the shorter mating length makes it the right answer for low-profile daughtercards where the right-angle 9-103323-0-09 would add too much z-height.
TE Connectivity 2-826631-4 (AMPMODU Mod II, 24 positions, single row, 0.100" pitch, right-angle, gold mating 3.90 µin / tin post 118.1 µin, PBT insulation, UL94 V-0, 5 A) — the 5 A and gold-mating variant used where the mating cycle count is high (test fixtures, modular assemblies) or where signal integrity at the contact interface matters more than unit cost.

The 3 A rating on the tin-plated members and the 5 A rating on the gold-plated members both refer to single-contact current in still air at room temperature. Real-world derating in a multi-position header housing with all positions energized will pull the per-contact figure down, but the 3 A / 5 A specification sets the envelope a designer plans against.

The unshrouded breakaway design means the buyer cuts the position count to length at assembly — which is why the same base product number is quoted at multiple position counts and why allocation tends to bite unevenly across the line. A factory that is short on the 0.025" square pin strip will allocate against the higher-volume position counts first (the 10-, 20-, 40-position), leaving the odd-count and high-count members with longer lead times.

The TE Connectivity AMP-Latch shrouded IDC ribbon-cable header

Where the AMPMODU Mod II handles board-to-board, the AMP-Latch line handles board-to-cable / wire-to-board for ribbon-cable and discrete-wire interconnects. The catalog carries two reference points worth knowing:

TE Connectivity 499582-8 (AMP-Latch, 34 positions, dual row, 0.100" pitch, 1 A per contact, 250 VAC, gold or gold-palladium mating, press-fit and solder termination, shrouded 4-wall with keying slot and mounting flange) — the 34-circuit dual-row member used at the breakout end of a 34-position IDC ribbon cable from a PLC or distributed I/O block.
TE Connectivity 1-102155-2 (AMP-Latch, 64 positions, dual row, 0.100" pitch, 250 VAC, 1 A per contact, gold or gold-palladium mating, through-hole solder, shrouded 4-wall, 0.549" insulation height) — the 64-position member that doubles the circuit density for higher-density ribbon-cable runs, typical on the back of larger PLC racks and on telecom backplane-to-daughtercard telemetry paths.

The 250 VAC rating and 1 A per contact place the AMP-Latch squarely in the signal and low-power control side of the design, not the power side. The shrouded 4-wall housing with the keying slot is the detail that prevents mis-mating in the field — important when the ribbon cable is being plugged by a maintenance technician and not by an automated assembly cell. The push-pull fastening is the standard for this class; it is positive enough for vibration environments (industrial cabinets, transit, mobile equipment) without being a threaded coupling that requires a tool.

For IDC ribbon-cable applications, the mating half is typically a TE Insulation Displacement Connector (IDC) socket or a third-party compatible — the AMP-Latch pin header is the board side, the IDC socket terminates the ribbon cable. Independent-channel sourcing has to manage both halves; we cover that in the cross-reference section below.

The Amphenol ICC (FCI) cross-reference landscape

The FCI legacy (now Amphenol ICC) line sits next to TE's in almost every 2.54 mm signal-header application. The catalog carries the three families that matter for a buyer trying to source a 0.100" signal header in 2026:

Amphenol ICC (FCI) BergCon receptacle — 76314-111LF (22 positions, dual row, 0.100" pitch, gold mating 30.0 µin, through-hole solder, UL94 V-0, glass-filled polyester, blue housing) is the FCI legacy dual-row receptacle. The BergCon receptacle mates with a BergStik II or compatible 0.100" header; the gold mating finish (30.0 µin / 0.76 µm) is the durability layer for repeated mate cycles in modular assemblies.
Amphenol ICC (FCI) Dubox receptacle — 89882-340LF (40 positions, single row, 0.100" pitch, right-angle through-hole, gold mating 30.0 µin, UL94 V-0, glass-filled thermoplastic, blue housing) is the right-angle single-row receptacle, used on the daughtercard side of a board-to-board stack where the height envelope matters.
Amphenol ICC (FCI) BERGSTIK II header — 69190-109HLF (9 positions, single row, 0.100" pitch, 3 A, gold or GXT mating 30.0 µin, through-hole press-fit and solder, unshrouded, push-pull, PCT housing, UL94 V-0, -65°C to 130°C) is the FCI counterpart to the AMPMODU Mod II 9-103323-0-09. The 92417-224HLF (24 positions, dual row, 0.100" pitch, 5 A, 110 V, gold or GXT mating 15.0 µin, through-hole solder, unshrouded, push-pull) is the dual-row counterpart to the AMPMODU 4-103322 series.
Amphenol ICC (FCI) Dubox shrouded board-to-wire header — 76382-410LF (10 positions, single row, 0.100" pitch, 3 A, tin mating 78.7 µin, right-angle through-hole, shrouded 4-wall, friction lock, -40°C to 125°C) is the FCI counterpart to the AMP-Latch shrouded line on the board-to-wire side.

The cross-reference is real but partial. A BergStik II 69190-109HLF will mechanically mate with an AMPMODU Mod II receptacle, but the cosmetic and dimensional differences (insulation height, pin shoulder geometry, standoff height) mean the two are not drop-in equivalents at the assembly level — the PCB layout can usually accept either, but the housing stand-off and the mating pin length differ enough to be checked against the mechanical envelope of the mating housing before committing the BOM line. We treat FCI ↔ TE cross-references as mechanical-compatible, footprint-compatible in most cases, and not as procurement-substitutes without a sample run.

What the market signals are saying about 2026 supply

Reading the independent-channel order book and the public market signals together gives the picture we are working against in Q3 2026.

Signal 1: Tightening on tin-plated AMPMODU Mod II breakaway headers. The 3 A tin-plated members (the 9-103323-0-09, 9-103323-0-39, 4-103322-0-18, and 4-103327-0-09 part numbers) are running longer than the Q1 2026 baseline. Allocation bites first on the 36- and 40-position dual-row members because the factory pin-strip is the shared upstream constraint. The 9- and 10-position single-row members tend to clear the same allocation cycle faster because the per-strip pin count is lower.

Signal 2: Gold-plated variants on extended lead-times even outside allocation. The 2-826631-4 (5 A, gold mating 3.90 µin, right-angle) and the equivalent 5 A single- and dual-row AMPMODU members have carried 16-20 week lead-times through Q2 and into Q3 2026. The factory capacity for selective gold plating on the 0.025" square pin is a separate constraint from the pin-strip stamping capacity, and it does not relax when the underlying allocation eases.

Signal 3: AMP-Latch shrouded IDC ribbon-cable headers tracking with industrial automation retrofits. The 499582-8 (34-position dual-row) and 1-102155-2 (64-position dual-row) members are running longer than the Q4 2025 baseline. The pull here is from the wave of industrial automation retrofits visible in the Hannover Fair 2026 messaging and from the PLC / distributed I/O refresh that has run through 2026.

Signal 4: FCI BERGSTIK II and Dubox lines as the parallel sourcing lane. The Amphenol ICC (FCI) side of the catalog — BergCon 76314-111LF, Dubox 89882-340LF, BERGSTIK II 69190-109HLF and 92417-224HLF — is sourcing more cleanly than the TE side on the same form-factor. For a buyer who can footprint-verify and run a sample, the FCI legacy is the realistic second-source lane in 2026.

Signal 5: AI-server backplane signal paths (management and telemetry layers) as a sustained pull. The TE Q3 FY26 earnings call on July 22, 2026 highlighted AI data-center demand as a structural driver. The 2.54 mm header is not the high-speed side of the AI server (that is Samtec, Molex, TE high-speed board-to-board), but the management-plane, telemetry, and FRU-ID paths inside the server and across the rack still run on 0.100" headers in significant volume. The dual-row higher-position-count members (the 36- and 40-position 4-103322-0-18, 92417-224HLF, 89882-340LF) are the SKUs that show up on those signal paths.

How independent-channel sourcing actually works on this line

Three things matter to a buyer working an AMPMODU or AMP-Latch BOM line through an independent distributor in Q3 2026.

MOQ and reel vs. bulk packaging. The catalog here quotes in bulk packaging as the default for the AMPMODU Mod II headers (9-103323-0-09, 9-103323-0-39, 4-103322-0-18, 4-103327-0-09, 2-826631-4) and tray / tube packaging for the FCI BERGSTIK II (69190-109HLF, 92417-224HLF) and Dubox (89882-340LF, 76382-410LF). Minimum order quantities on the higher-position-count breakaway headers tend to sit at the strip-level cut, not at the 1-piece reference price — meaning a quote for 50 pieces of a 36-position dual-row breakaway is effectively a quote for a partial strip. Plan the BOM order quantity against the strip-cut minimum, not against the reference price.

Cross-reference sample runs before committing the substitution. The FCI BERGSTIK II ↔ TE AMPMODU Mod II compatibility is real but not free. The insulation height, the mating pin length, the housing stand-off, and the push-pull latch geometry all differ enough between the two product lines that a board designed for one and stuffed with the other can fail at the housing interference or the mating engagement depth. We recommend a 5- to 10-piece sample run of the cross-reference candidate before releasing the substitution. The same caveat applies to the AMP-Latch ↔ Dubox shrouded header cross.

Lead-time honesty. Independent-channel lead times on the 2.54 mm signal-header family in Q3 2026 are running 8-16 weeks for the tin-plated AMPMODU Mod II members on allocation, 16-22 weeks for the gold-plated 5 A members, and 10-14 weeks for the AMP-Latch shrouded members. The FCI BERGSTIK II and Dubox lines are running 6-12 weeks on equivalent form factors. If the buyer's production window is inside those numbers, the independent channel can carry the line; if the window is shorter, the buyer should be planning a factory-direct allocation discussion with the OEM in parallel.

What a buyer should put on the RFQ

A clean RFQ on this product family gives the independent distributor enough information to give a clean answer. The four pieces that move the quote from "contact for availability" to a firm price and lead-time:

Exact MPN or functional cross-reference — a specific AMPMODU Mod II base number and position count (e.g., 9-103323-0-09 with 9 positions, or 4-103322-0-18 with 36 positions dual row), or the FCI BERGSTIK II / Dubox / BergCon equivalent. Generic "2.54 mm header, 10 position" RFQs will get a generic answer; a specific cross-reference will get a specific answer.
Plating requirement — tin mating (the default on most AMPMODU Mod II and BERGSTIK II members), gold mating (the 2-826631-4 AMPMODU, the BergCon 76314-111LF, the Dubox 89882-340LF, the BERGSTIK II 69190-109HLF), or tin-lead (the 4-103322-0-18, 4-103327-0-09). The plating dictates the lead-time tier.
Orientation and termination — vertical through-hole (the 4-103327-0-09), right-angle through-hole (the 9-103323-0-09, 9-103323-0-39, 2-826631-4, 89882-340LF), or press-fit + solder (the 499582-8, 69190-109HLF). Mismatches here are the most common cause of a "we ordered the right part number, but the board does not accept it" outcome.
Target quantity and required delivery window — including the strip-cut minimum where the part is a breakaway header. A 50-piece quantity on a 36-position dual-row breakaway is a partial-strip cut; the per-piece price reflects that. A 5,000-piece quantity is a multi-strip run; the per-piece price steps down.

The honest limits of the independent channel

We are an independent connector and interconnect distributor. We are not an authorized distributor or representative of TE Connectivity, Amphenol, FCI, Molex, Hirose, Phoenix Contact, Würth Elektronik, or any other manufacturer listed in our catalog. All brand names and trademarks are the property of their respective owners. What that means in practice is that we source against the BOM line and ship against an RFQ; we do not hold OEM warranty on the parts, and we do not represent that the parts are factory-fresh in the OEM-sealed-bag sense on every order. For most retrofit, MRO, and allocation-bridge applications that is exactly the right answer — the buyer needs the part on the line, with a clean paper trail, and not an OEM allocation slot. For warranty-sensitive designs (medical, aerospace, certain automotive safety) the buyer should be sourcing factory-direct or through an authorized distributor regardless of price.

We will quote honestly against the available stock and the factory lead-times we can confirm at the time of the RFQ. Where the line is genuinely tight, we will say so and we will suggest the FCI BERGSTIK II / Dubox parallel lane where it is a real option. Where the cross-reference is not real (different pitch, different current rating, different insulation material), we will say that too.

Closing thought for the buyer's desk

The 2.54 mm signal-header family is not exotic, but in Q3 2026 it is not boring either. The combination of PCB-side tightening, copper-cost pass-through, an industrial-automation retrofit wave visible in the Hannover Fair 2026 messaging, and the AI-server backplane signal-path pull has put real pressure on specific position counts and platings in the AMPMODU Mod II line and on the AMP-Latch shrouded IDC ribbon-cable header line. The catalog depth on the TE side (the 9-103323-0-09, 9-103323-0-39, 4-103322-0-18, 4-103327-0-09, 2-826631-4, 499582-8, and 1-102155-2 references cited above) and the parallel FCI BERGSTIK II / Dubox / BergCon lane (the 69190-109HLF, 92417-224HLF, 76382-410LF, 76314-111LF, and 89882-340LF references) give an independent channel a real window to carry the line through the tight quarters, as long as the RFQ is specific enough to be quoted against. For deeper position counts, gold-mating variants, and IDC ribbon-cable assemblies, plan for 12-20 week windows and book the order before the EMS window collapses the schedule.
