What the 93690-101-20LF is
The Amphenol ICC BERGSTIK 93690-101-20LF is a dual-row 20-position breakaway header in the BERGSTIK series, operating at 0.100" (2.54 mm) pitch — the same footprint as the industry-standard 0.100" header format used across board-to-board and cable interconnect applications. The connector is unshrouded, meaning it is a bare pin field with no polarizing keying tower — which makes it flexible for right-angle or vertical stacking but requires the designer to manage alignment and polarisation through the mating receptacle or PCB layout. Contact platings are split across the interface: the mating side carries Gold GXT plating at 30.0 µin (0.76 µm), which is the wear-rated surface for repeated plug cycles; the solder-post side is tin-plated at 39.4 µin (1.00 µm) — optimised for solder wetting and long-term shelf stability rather than mating durability. The copper alloy contact body carries 5 A per circuit at the rated voltage of 110 V. The termination supports press-fit insertion into a plated-through hole without primary soldering — the post is driven into the PCB hole and the interference fit holds it mechanically. Solder termination is also listed, giving the assembler a choice depending on the board finish, hole size, and whether the application requires a reflow or wave-solder process. The fastening type is listed as push-pull, meaning the header is retained by the interference fit of the post in the hole rather than by a separate lock. The housing is black thermoplastic rated UL94 V-0, with a 0.100" (2.54 mm) insulation height and a total contact length of 0.582" (14.78 mm). The post projection above the board surface is 0.177" (4.50 mm), and the mating pin engagement length is 0.295" (7.49 mm). All 20 positions are loaded.
Where it is used
The BERGSTIK 93690-101-20LF sits in board-to-board and cable interconnect roles — it is listed as a board-to-board or cable style connector, which means it functions as either a vertical or right-angle pin header on a PCB that mates with a matching IDC receptacle, crimp housing, or another board-level header. The breakaway design allows the strip to be snapped to any even position count below 20, making it common for prototyping and short-run production where the exact circuit count is not fixed at design time. The 2.54 mm pitch and 5 A rating suit it for signal and low-power distribution rather than high-current bus rails.
What the key ratings mean
The 0.100" (2.54 mm) pitch matches the industry-standard header footprint used across board-to-board and cable interconnect. The 20-position dual-row layout has 0.100" row spacing and 0.100" insulation height, which determines board standoff in a mated pair. The 5 A per circuit rating is the single-contact limit. At 0.100" pitch with two rows, the contact density is moderate — power routing through the inner pins is viable but must be checked against the housing temperature rise ceiling. The 110 V rating is listed; confirm this against the working voltage of the target circuit before committing.
Sourcing and the BOM line
The 93690-101-20LF is listed Active. The base product number is 93690 — confirming the position count (20) and the termination type (press-fit or solder) against your BOM line is the first check. The matching half must be confirmed separately: the mating receptacle or cable housing is not specified in this listing, and the breakaway header's unshrouded design means polarisation is handled by the mating component or the PCB footprint — not by the header itself.
