What This PCB Pin Socket Does in the Assembly
The 2-5331677-2 is a PCB-mount pin receptacle that accepts round pins or component leads within a 0.030" to 0.033" diameter range. The open-bottom design lets the pin pass through the socket body, which is useful for through-hole alignment or when the pin protrudes past the contact beam. Rated for -65°C to 126°C operation, it suits automotive underhood, industrial enclosures, and outdoor telecom gear where temperature swings are severe.
Supplied in bulk packaging, which means loose parts in a bag — not tape-and-reel, so hand placement or tube feeding is expected.
Mounting and Fit Details
Solder termination with no tail — the socket body sits flush on the PCB pad. The mounting hole diameter is 0.062" to 0.063", so the board drill must stay within that range for a press-in fit before soldering. Overall length is 0.138" (3.51 mm) and socket depth is 0.125" (3.18 mm), meaning the pin insertion depth is about 0.125" before bottoming out.
