What this connector is
The Amphenol FCI 87900-168HLF is the 68-position member of the BERGSTIK II series — a dual-row unshrouded male pin header designed for board-to-board stacking at 0.100" (2.54mm) pitch. Square pins in phosphor bronze, all 68 circuits loaded, gold or Gold GXT contact plating at 30.0µin (0.76µm) on the mating face. The push-pull fastening type relies on the mating receptacle's friction fit rather than a screw lock, which is standard for this series and suits low-vibration internal board-to-board applications.
Where it goes and how it mounts
Board-to-board style headers at 0.100" pitch are the standard vertical interconnect for daughter-card to backplane or mid-plane routing in industrial automation, instrumentation, and consumer electronics. The 0.100" row spacing matches the industry-standard 2.54mm grid, so routing density is predictable. Through-hole mounting with 0.120" post length requires adequate pad diameter and hole size for wave or hand-solder assembly; the unshrouded header means there is no polarisation key on the housing side — alignment relies on the receptacle housing's polarizing ribs or the board layout itself.
Material and compliance
The insulator is rated UL94 V-0 for flame retardancy, which is the minimum required for commercial equipment enclosures. Contact material is phosphor bronze throughout. If REACH compliance documentation is required for the build, confirm against the current manufacturer declaration.
