Pitch, Positions, and Plating for Signal Routing
The 77315-818-12LF: The unshrouded design allows direct access to the square pins for wire-wrapping or test probing, though it offers no keying against mis-mating. The post length of 0.120" (3.05 mm) suits typical 1.6 mm thick PCBs with through-hole soldering. The post is tin-plated (78.7 µinch) for solderability.
