What the BERGSTIK is
The Amphenol ICC 93690-102-10LF is a 10-position dual-row BERGSTIK header in the 93690 series — a family of unshrouded, breakaway-style square-pin headers intended for board-to-board or cable-level interconnects. The dual-plating grade is the detail that separates signal-duty from power-duty sizing on this series: the mating face carries Gold GXT plating at 30.0 µin (0.76 µm) over copper alloy, while the solder-post side is tin at 39.4 µin (1.00 µm). The push-pull fastening keeps the header seated without jack-screws or hardware — a feature that matters in dense board-stacks where access is tight and a vibration-loosened screw would be a field callback. The black thermoplastic housing meets UL94 V-0.
Ratings that drive the fit decision
At 5 A per circuit and 110 V the 93690-102-10LF sits squarely in signal-duty territory — the gold-mating finish (not a thin flash) means the contact can handle repeated mating cycles without the tin-wear that limits lower-grade headers. Row spacing is 0.100" (2.54 mm), matching standard 0.100-inch pitch IDC and DIL footprints so the board routing and legacy replacement search is straightforward. The 0.100" (2.54 mm) insulation height gives a mated stack that clears most adjacent components on a single-board assembly.
Where this series belongs in the harness
The BERGSTIK unshrouded header is a board-to-board and board-to-cable header — the breakaway-style body means you can score and snap the tail to a shorter position count if the BOM lands between standard cuts.
