The FCI 87185-116HLF is a 16-position, single-row BergStik® II unshrouded header on the standard 0.100" (2.54 mm) pitch. It's a through-hole solder-terminated male pin strip — the kind you see on breadboard prototypes, test fixtures, and legacy card-edge interconnects where the mating half provides the alignment.
The 0.100" pitch is the classic DIP/breadboard spacing — the footprint is a straight row of 0.025" square pins on 0.100" centers, so it drops into a standard perfboard or a PCB laid out for legacy 0.100" headers. The 5 A per-contact rating is signal-level current, not bus-bar power; the limiting factor is the 0.100" pin spacing and the 30 °C temperature rise in the UL94 V-0 black thermoplastic housing. Being unshrouded means the pins are fully exposed — there's no polarization key to prevent a 180° mis-mate. The mating receptacle or housing needs to provide its own alignment and keying. For a board-to-board stack, the 1.238" overall contact length plus the 0.100" insulation height define the minimum z-height budget between the two PCBs.
No official cross-reference or direct equivalent is on record, so the BOM line should be specced against the exact 16-position, single-row, 0.100" pitch footprint.
