Product details

KK254 11-circuit breakaway header

The 0423770788 is the 11-circuit member of the Molex KK254 breakaway header line, unshrouded with a push-pull fastening system. Tin-plated mating and post contacts at 100.0µin (2.54µm) thickness, through-hole right-angle mounting, and a UL94 V-0 nylon housing.

Position count across the KK254 series

This 11-position header uses the same 0.100" (2.54mm) pitch and single-row layout as the rest of the KK254 series — match the position count to the circuit count; the footprint and board layout are shared across the series.
