Mates with Molex KK254 crimp receptacle housings (series 6471, 2695) using the matching crimp terminals. The unshrouded profile keeps the header height low — 0.090" (2.29 mm) insulation height — which helps in tight board-to-wire spacing.
Mating contacts are gold over nickel, 15.0 µinch (0.38 µm) thick — a typical specification for 100–500 mating cycles in controlled environments.
ROHS3 compliant, with no restricted substances above threshold limits.
The mating pitch is 0.100" (2.54 mm), single row. This is the standard KK254 spacing and matches all KK254 crimp receptacles.
