The 1-826632-2: The through-hole termination with a 0.126" (3.20mm) post length fits standard 1.6mm PCBs. Overall contact length is 0.500" (12.70mm), with a mating pin length of 0.264" (6.70mm) — enough to engage a standard socket without bottoming out.
Current Capacity and Contact Plating
That gold layer is thin — fine for occasional mating in a controlled environment, but in a field-service application with repeated connect-disconnect cycles, the gold will wear through faster than a 15 µinch or 30 µinch plating. The tin-plated posts (118.1 µinch) handle the solder joint side without issue.
