What this pin receptacle accepts and where it fits
The 1-5380758-1: This is a single-circuit PCB pin socket from TE Connectivity's AMP Connectors line, built to accept a mating pin diameter from 0.036" to 0.054" (0.91mm to 1.37mm). Termination is solder-only, with no tail — the socket sits flush into a plated through-hole sized for a mounting hole diameter of 0.086" to 0.089" (2.18mm to 2.26mm).
Mounting and board fit details
The socket depth is 0.145" (3.68mm), and the overall length is 0.262" (6.65mm). The flange diameter is 0.125" (3.18mm), and the pin hole diameter is 0.054" (1.37mm). Board thickness spec is 0.156" (3.96mm) — the socket's tail-less design relies on the solder fillet for mechanical retention, so the hole size and board thickness must match the listed mounting hole diameter range.
