What this pin socket accepts and how it mounts
The 5050863-6 is a press-fit PCB pin socket from TE Connectivity's Series 2 family. It accepts pin diameters from 0.014" to 0.026" (0.36 mm to 0.66 mm) — covering common component leads, test pins, and header posts within that range. The open-bottom design lets the pin pass through the socket body, which aids solder-joint inspection and allows through-hole termination on the far side of the board. No tail means the socket sits flush with the PCB surface after soldering. Beryllium copper delivers high yield strength and flexural fatigue life — the socket maintains contact force over repeated insertions without permanent set. Tin plating is the standard choice for moderate-cycle, cost-sensitive interconnects; the 100 µinch thickness provides a robust wear surface for production and field-service reconnections.
Dimensions and board fit
Overall length is 0.260" (6.60 mm), with a socket depth of 0.247" (6.27 mm) — the pin insertion depth before bottoming out. The flange diameter is 0.070" (1.77 mm), and the recommended mounting hole diameter is 0.052" (1.32 mm). These dimensions define the PCB drill size and the keep-out zone around each socket. The beryllium copper contact retains its spring properties across this entire range, unlike phosphor bronze which loses stiffness at the high end.
