Pitch, Positions, and Footprint Fit
The 1586174-1: The 6.35 mm pitch on both the row-to-row and contact-to-contact axes gives a 12.7 mm square footprint for the 6 positions — a generous keep-out that suits power routing on 2-layer boards. The 0.155-inch (3.94 mm) solder post length fits standard 1.6 mm PCBs with enough tail for a solid fillet.
