What this header fits
The 76384-415LF is the 15-position single-row member of the Amphenol ICC (FCI) Dubox shrouded header line, built for board-to-cable/wire connections with a friction lock to hold the mating half.
Tin plating and the friction lock
The 78.7 µin tin mating finish suits moderate mating-cycle duty in equipment where the friction lock keeps the pair engaged under vibration — the 2-wall shroud guides the receptacle into alignment before the lock snaps. Tin-to-tin contacts need a minimum normal force to wipe through surface oxide; the Dubox square-pin geometry delivers that without relying on gold.
