The FCI 87185-430HLF is a 30-position, single-row BergStik II unshrouded pin header designed for board-to-board or wire-to-board interconnect on a standard 0.100" (2.54 mm) pitch. Through-hole solder termination with square male pins in a black UL94 V-0 rated housing.
The 0.100" pitch is the de facto standard for through-hole headers — your existing 2.54 mm footprint pattern works without a layout change. 30 positions on a single row means the header spans about 2.95 inches of board edge; confirm the keep-out zone clears adjacent components.
