The socket depth is 0.125\" (3.18mm), so the pin insertion depth is defined by that bore, not the overall length. ## Temperature range and operating environment Rated for -65°C to 126°C, this socket handles the thermal extremes of aerospace, military, and industrial enclosures — the beryllium copper spring maintains contact force across that span without relaxation. ## How this compares to sibling 2-5331272-7 The closest functional alternative is 2-5331272-7 — same socket depth, length, contact material, and gold plating thickness. The difference: 2-5331272-7 accepts a larger pin diameter range of 0.022\" to 0.025\" (0.56mm to 0.64mm). If your header pin is 0.020\", this 2-5331272-3 is the correct fit; if it's 0.024\", step to the -7. Closed-bottom design with no tail — the socket is solder-terminated into a 0.052\" (1.32mm) mounting hole. The flange diameter is 0.070\" (1.77mm), which sets the annular ring clearance on the PCB.","metaTitle":"2-5331272-3 TE Connectivity PCB Pin Socket, Gold","metaDescription":"TE Connectivity AMP Connectors 2-5331272-3 PCB pin socket, accepts 0.018\"~0.021\" pin diameter, gold 30µin plating, beryllium copper contact, -65°C~126°C, RoHS.","metaKeywords":null},"attributes":{"series":"2","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","PCB Pin Sockets"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"2","Package":"Bulk","Features":"Closed Bottom","Tail Type":"No Tail","Termination":"Solder","Socket Depth":"0.125\\\" (3.18mm)","Tail Diameter":"-","Contact Finish":"Gold","Product Status":"Active","Board Thickness":"-","Flange Diameter":"0.070\\\" (1.77mm)","Insertion Force":"-","lifecycle_stage":"unknown","Contact Material":"Beryllium Copper","Length - Overall":"0.138\\\" (3.51mm)","Pin Hole Diameter":"-","Base Product Number":"5331272","Accepts Pin Diameter":"0.018\\\" ~ 0.021\\\" (0.46mm ~ 0.53mm)","Operating Temperature":"-65°C ~ 126°C","Mounting Hole Diameter":"0.052\\\" (1.32mm)","Accepts Square Pin Size":"-","Contact Finish Thickness":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.59000","currency":"USD"},{"qty":10,"price":"$0.55200","currency":"USD"},{"qty":25,"price":"$0.54920","currency":"USD"},{"qty":50,"price":"$0.53560","currency":"USD"},{"qty":100,"price":"$0.45930","currency":"USD"},{"qty":250,"price":"$0.41548","currency":"USD"},{"qty":500,"price":"$0.39240","currency":"USD"},{"qty":1000,"price":"$0.34393","currency":"USD"},{"qty":2500,"price":"$0.33931","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9f3d3a5c2993870cf3a2b51069e918ed.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 2-5331272-3 and how is it quoted?","answer":"2-5331272-3 is sourced through independent distribution channels."},{"question":"What is the pin diameter range for 2-5331272-3?","answer":"The socket accepts pin diameters from 0.018\" to 0.021\" (0.46mm to 0.53mm).
