The FCI / Amphenol ICC 87185-409HLF is a 9-position, single-row BergStik® II unshrouded pin header. It's a through-hole solder-terminated board-to-board interconnect on the standard 0.100" (2.54mm) pitch, making it footprint-compatible with breadboards, perfboards, and the vast ecosystem of 0.100" pitch ribbon-cable IDC receptacles.
What the pitch and plating mean for your build
The 0.100" (2.54mm) pitch is the de facto standard for 0.100" IDC ribbon-cable connectors — this header mates directly with the matching BergStik receptacle housing and a standard 9-position IDC socket.
