8 positions at 3.96 mm pitch — BOM-fit check
Molex 1718131008 is an 8-position, single-row male header from the KK396 series, on 0.156" (3.96 mm) pitch. That pitch is the standard for the KK396 family, so the footprint lines up with the matching crimp housings and PCB receptacles. The friction lock keeps the mating half seated under vibration — a detail that matters when this header lives inside an automotive or industrial enclosure where the cable gets tugged.
Gold mating finish — why it is there
The post finish is tin, 100.0 µin, which solders cleanly into the through-hole board and avoids galvanic mismatch with the PCB pad finish.
This header mates with the KK396 crimp receptacle housings — the same 3.96 mm pitch, single-row, friction-lock compatible.
