Pin Receptacle for Precision Signal Paths
The 5050864-1 is a closed-bottom pin receptacle from TE's Series 3, designed to accept pin diameters from 0.026" to 0.033" (0.66 mm to 0.84 mm). Solder termination with no tail keeps the profile low — the overall length is 0.257" (6.53 mm) and the socket depth is 0.244" (6.20 mm).
Temperature Range and Material Choices
Rated for -65°C to 126°C, this receptacle covers applications from cold-soak avionics to under-hood automotive. The beryllium copper contact maintains its spring force across that range — important when the board sees thermal cycling and the pin-to-receptacle interface must not frett. The 30.0 µinch gold plating is a mid-grade choice — above the flash plating common on commodity tin receptacles.
