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.","metaTitle":"3-331272-8 TE Connectivity PCB Pin Socket, Gold","metaDescription":"3-331272-8 TE Connectivity AMP PCB pin socket, accepts 0.018\"-0.021\" pin diameter, gold plating, beryllium copper, -65°C to 126°C.","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":"Open 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":"331272","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":"$0.9000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.90000","currency":"USD"},{"qty":10,"price":"$0.86100","currency":"USD"},{"qty":25,"price":"$0.82320","currency":"USD"},{"qty":50,"price":"$0.81200","currency":"USD"},{"qty":100,"price":"$0.70950","currency":"USD"},{"qty":250,"price":"$0.68292","currency":"USD"},{"qty":500,"price":"$0.64500","currency":"USD"},{"qty":1000,"price":"$0.55773","currency":"USD"},{"qty":2500,"price":"$0.51599","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fd57627a30d05e3a58363eef1379d984.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What pin diameter does 3-331272-8 accept?","answer":"It accepts pin diameters from 0.018\" to 0.021\" (0.46mm to 0.53mm)."},{"question":"What is the socket depth of 3-331272-8?","answer":"The socket depth is 0.125\" (3.18mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-331272-8","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/3-331272-8 when reusing this data.
