The Amphenol FCI 87916-416HLF is a 16-position unshrouded male pin header from the BERGSTIK II series, on a 0.100" (2.54 mm) pitch. It's a single-row, through-hole solder part with a push-pull mating interface — no latch, no shroud, just the pins. This is a straight-up board-to-board interconnect, typically used where you need a low-cost, moderate-density signal or power connection between two PCBs, or as a pin header for a mating IDC or crimp receptacle.
Within the BERGSTIK II family, the 87916-416HLF is a 16-position variant of a common unshrouded header format. The key decision point against a lower-position sibling (say, a 10-position) is simply the circuit count — the pitch, current rating, and plating are identical across the series.
The push-pull retention means there's no locking latch; the friction of the pin-to-socket interface holds it together. The through-hole solder termination is robust for manual or wave-solder assembly.
The overall contact length of 1.058" (26.87 mm) with a 0.830" (21.08 mm) mating section gives a generous wipe length, which helps with contact reliability on the first mate.
