The Amphenol BERGSTIK® 93690-106-50LF is a 50-position, 2-row, unshrouded breakaway header on a standard 0.100" (2.54mm) pitch. It's a male pin header with a square contact shape, designed for through-hole mounting with either press-fit or solder termination. This is the high-density end of the BERGSTIK breakaway family; the 0.100" row spacing gives the same footprint as legacy 0.100" x 0.100" grid patterns, meaning it drops into existing board layouts without a layout change.
The 0.100" (2.54mm) pitch and row spacing are the classic 0.100" x 0.100" grid — any board laid out for a standard 0.100" header accepts this part without a respin. The 5A per-contact rating at 110V is enough for signal lines and light power distribution, but if you're pushing 5A on every pin simultaneously, check the derating curve for your ambient temperature; the UL94 V-0 thermoplastic housing handles the heat, but the current limit is per-contact, not a total bus rating. The press-fit option is a genuine advantage for backplane or multi-board assemblies where you want solderless assembly and easier rework.
Against the 10-position version (93690-102-10LF) in the same BERGSTIK series, the difference is purely positional: 50 circuits vs 10 circuits at the same 0.100" pitch and 5A rating. The 50-position header takes up a longer board footprint — 2.500" of edge real estate versus 0.500" — but the electrical and mechanical specs are identical.
