The 5-146258-2: Each contact carries 3A, typical for signal-level loads, and the tin-plated mating surface suits moderate-cycle applications where gold is not required. The breakaway construction means this 4-position part is a snapped segment of a longer pin strip — the same footprint works for any even pin count in the same series.
Board-fit dimensions and routing
The 0.100" row spacing and 0.100" pitch match standard 2.54mm perfboard and breadboard layouts, so no custom footprint is needed for prototyping. Mating pin length is 0.230" (5.84mm), post length is 0.090" (2.29mm) — the post sits flush with a 1.6mm PCB after solder, leaving the pin exposed for the receptacle. Overall contact length of 0.410" (10.41mm) keeps the mated stack height within a typical 8-10mm envelope for low-profile board stacking.
