Product details

Pin fit and contact design

The 3-331272-8: This PCB pin socket accepts pin diameters from 0.018" to 0.021" (0.46mm to 0.53mm), making it a tight fit for standard component leads or test pins in that range.

Solder termination with no tail — the socket sits flush on the board after soldering, with a socket depth of 0.125" (3.18mm) to fully seat the pin. The open-bottom feature allows solder paste or flux to escape during reflow, reducing voiding risk.

Environmental range and sourcing

Rated for -65°C to 126°C, this socket suits applications from cold storage to underhood automotive environments.
