What this connector is
The FCI BERGSTIK II 86832-418HLF is a dual-row unshrouded male pin header at the 0.100" (2.54 mm) industry-standard pitch — the workhorse footprint that cross-mates with most 2.54 mm IDC receptacles, wire-board housings, and card-edge fingers in the same family. This 18-circuit member sits at the mid-range position count for the series, between the smaller counts used for discrete signal bundles and the larger counts that handle parallel bus or power rail arrays. The contact material is phosphor bronze with tin plating at 100 µin (2.54 µm) on the mating interface — a finish calibrated for reconnection cycles in the low-to-moderate range (hundreds of mates rather than thousands). The push-pull fastening type means it relies on the mating connector's friction lock rather than a threaded or screw-lock retention; confirm the receptacle housing carries a positive latch if vibration is a factor in the application. Rated 5 A per contact at the listed 110 V — a combination that covers most low-voltage signal and moderate-power distribution uses in industrial controls, instrumentation, and automation equipment. The UL94 V-0 flammability rating on the housing material means it clears the ignition-resistance requirement for most industrial and commercial equipment enclosures without requiring a supplemental flame barrier. Through-hole solder tails with a post length of 0.100" (2.54 mm) give mechanical withdrawal resistance that SMT-only headers cannot match — relevant when the daughter card will see field service or repeated mating cycles. The insulation height of 0.100" (2.54 mm) and overall contact length of 0.525" (13.34 mm) define the stack geometry for board-to-board stacking or card-edge entry applications.
What the ratings mean for your BOM
The 18 positions in two rows is a common mid-size count for parallel signal or low-current power distribution; the board footprint matches any compatible 2.54 mm header in the BERGSTIK II family. The 5 A per contact rating is the headline figure, but the tin plating grade sets the practical ceiling for reconnect cycles. Tin-plated contacts in an unshrouded push-pull header are not the right choice for applications requiring more than a few hundred insertion cycles — if your product will see repeated field mating, look at the gold-plated BERGSTIK variants or specify a housing with a positive lock that adds secondary retention. 110 V is the voltage rating — adequate for signal-level and low-voltage power distribution. Do not use this header for line-voltage AC routing without re-examining creepage and clearance at the board level.
Sourcing and lifecycle
Listed Active. The BERGSTIK II series is a long-standing FCI (now Amphenol) product line with broad second-source availability — the 0.100" pitch format means this footprint is rarely single-sourced in a production build, which reduces the risk of a supply disruption cascading into an EOL panic. No official successor or cross-reference order code exists for this specific part. If you are rationalising a connector SKU list, the first step is confirming the 18-position count and the through-hole mounting requirement match the board layout — the pitch and dual-row format are shared across the full BERGSTIK II range.
Mating and termination
This is a male pin header — it requires a matching female IDC or receptacle housing in the same 0.100" (2.54 mm) dual-row pitch. The square pin cross-section accepts standard square post headers or ribbon-cable IDC sockets. Termination is through-hole solder. The 0.100" (2.54 mm) post length is stated for the standard PCB thickness range; for thick boards confirm the overall contact length of 0.525" (13.34 mm) provides adequate clinch or tail protrusion on the secondary side. All 18 positions are loaded — no open positions to accommodate future expansion or partial circuit usage. Size the circuit count to the exact requirement before committing to the part.
