The FCI 87185-413HLF is a 13-position, single-row, unshrouded male pin header from the BERGSTIK® II series. It is a board-to-board interconnect with a 0.100" (2.54 mm) mating pitch, designed for through-hole soldering. The contacts are square male pins made of phosphor bronze with a tin finish on both the mating surface and the solder posts — the mating-side tin plating is 100.0 µin (2.54 µm) thick. Rated at 5 A per contact and 110 V, this is a signal-level header suited for parallel board stacking or wire-to-board applications when mated with the matching receptacle.
What the key ratings mean for the fit
The 0.100" (2.54 mm) pitch is the legacy industry standard — it matches the footprint of most 0.100" grid prototype boards and existing PCB layouts. The 13-position count is the primary BOM check: confirm this matches the circuit count on your mating receptacle. The 5 A per-contact rating is the current ceiling at room temperature; for signal-level duty this is generous, but if you are carrying power across all 13 circuits simultaneously, derate per the manufacturer's temperature rise curve. The unshrouded design means there is no plastic polarisation key — the board layout and the mating receptacle must provide the alignment, and the header can be mated in either orientation if the receptacle is not keyed.
