What this connector is
The Amphenol FCI BERGSTIK 93690-102-32LF is a 32-position dual-row board-to-board or cable header in the 0.100-inch (2.54 mm) pitch BERGSTIK family. It carries male square pins, unshrouded, with a push-pull breakaway configuration — meaning the strip can be split into smaller header sizes during board assembly as needed. The connector mates with matching IDC receptacles or single-row BERGSTIK housings, and its through-hole termination accepts both press-fit insertion and conventional solder assembly.
Plating strategy — gold on the face, tin on the tail
The contact finish splits the plating by function: the mating face carries Gold GXT at 30.0 µin (0.76 µm) to survive repeated matings and maintain low contact resistance on the interface, while the post side is tin-plated at 39.4 µin (1.00 µm) for reliable solder-wetting. The thicker tin on the tail is not an afterthought — it is sized for the solder-side reflow thermal profile. The 5 A per contact rating applies per circuit at the mating interface; the termination side rating follows the same current path.
What the key ratings mean for the build
32 positions in a dual-row layout across a 0.100-inch pitch clears standard grids with ordinary solder mask clearance. The 110 V rating requires spacing confirmation on the board layout for mains-adjacent or higher-voltage signal paths. The push-pull breakaway allows the strip to be snapped to a smaller position count in the field or at assembly. The 0.100-inch (2.54 mm) insulation height and 0.399-inch (10.13 mm) contact engagement length give a moderate stack-height tolerance — suitable for vertical board-to-board stacking where the z-axis is not tightly constrained. The 0.685-inch (17.40 mm) overall contact length defines the minimum board-to-board clearance when used as a stacking pin. UL94 V-0 flammability on the housing material satisfies most industrial and commercial equipment flammability requirements without needing a separate fire-barrier assessment.
