Board-to-Board Header for Legacy and Prototype Layouts
The Amphenol FCI 87901-164HLF is a 64-position (2x32) dual-row unshrouded header from the BERGSTIK® II series, built on the classic 0.100" (2.54mm) pitch. It's a through-hole solder-terminated male pin header with a push-pull fastening system, designed for board-to-board or wire-to-board interconnect where a standard, unkeyed pin field is acceptable.
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing define the board footprint — this is the standard 0.1-inch grid that matches breadboard, protoboard, and legacy PCB layouts. The 64 positions (all loaded) mean the full 2x32 pin array is present; if your BOM calls for a 64-circuit header, this is a direct fit.
