Pin fit and socket depth
The 1-50871-8: This socket accepts a pin diameter from 0.056" to 0.065" — the range covers standard 0.062" round pins common in power and signal interconnects. The 0.275" socket depth means the pin seats fully without bottoming out on the PCB, leaving clearance for solder fillets or through-hole tails.
Material and plating for repeated mating
Solder termination with no tail — the socket sits flush on the board after soldering, which saves vertical space. The open-bottom feature lets solder wick up the barrel for a reliable joint. Mounting hole diameter is 0.101" to 0.103" — a standard #43 or #42 drill bit works. Bulk packaging means each socket is loose, not taped, so hand-assembly or selective placement is straightforward.
