It uses the industry-standard 0.100" (2.54mm) pitch, making it a direct fit for breadboard-compatible layouts and common female socket strips. The through-hole termination and push-pull fastening suit it for permanent board-to-board connections where the mating pair is not frequently disconnected.
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing define the board footprint — a 2x4 grid of 0.025" square pins. The 0.190" (4.83mm) mating pin length provides enough reach to engage standard female headers. The 0.120" (3.05mm) post length suits typical 1.6mm-thick PCBs. The 100 µ" (2.54µm) tin plating on both mating and post surfaces is adequate for moderate mating cycles (tens, not hundreds) and is cost-effective for production runs where gold is not required.
