What this socket accepts and where it fits
The 5050865-7 is a PCB pin socket from TE's Series 4 family, designed to accept round pins with a diameter of 0.034 to 0.041 inches (0.86-1.04 mm). The socket has no tail — it terminates directly to the board via solder, with a mounting hole diameter of 0.072 inches (1.83 mm). Contact material is beryllium copper, chosen for its high fatigue resistance and consistent normal force over repeated mating cycles. The tin finish at 100 µinch thickness provides a corrosion barrier suitable for moderate environments — think industrial controls, test equipment, or automotive interior where the connector sees occasional disconnect. Overall length is 0.260 inches (6.60 mm) with a socket depth of 0.247 inches (6.27 mm), meaning the pin insertion depth is nearly the full length of the socket.
Board integration notes
The knockout bottom feature allows the socket to be press-fit into a plated through-hole before soldering, centring the contact in the hole for consistent solder fillet formation. The 0.072-inch mounting hole diameter is the board-side footprint — match this to the PCB drill file; the flange diameter of 0.089 inches (2.26 mm) provides the annular ring target.
