As an unshrouded header, it mates with standard AMPMODU Mod II receptacles or any compatible 0.100" pitch female socket housing. The push-pull fastening means the mating connector provides the retention — typically a latch or friction lock on the receptacle side. Common mating parts include TE 5-146256-7's counterpart receptacles in the same series, such as the 5-146256-7's matching female connector (not listed here but available in the AMPMODU Mod II family).
Current rating is 3A per contact at ambient temperature. The insulation height of 0.090" (2.29mm) is low-profile, keeping the header close to the board surface.
