The 5-146257-7: The 0.100" row spacing matches the mating pitch, so a single-row receptacle won't fit; you need a dual-row female housing or socket strip. The 0.230" (5.84mm) mating pin length provides enough engagement depth for most standard socket connectors, including TE's AMPMODU female headers and crimp housings. The unshrouded design keeps the profile low — 0.090" (2.29mm) insulation height above the board — which helps in tight z-height budgets.
Rated 3A per contact, with an operating range from -65°C to 105°C. The tin-plated solder tails (100 µinch) are compatible with standard wave solder processes.
