The contact is beryllium copper with 10.0 µin gold plating, terminated via a press-fit knurled barrel into a 0.138\" mounting hole — no soldering required. ## Mounting and pin acceptance range The 0.138\" (3.50 mm) mounting hole diameter and knurled press-fit barrel hold the socket in place without secondary retention. The 0.165\" socket depth matches the overall length — the tail type is No Tail, so the socket sits flush with the board surface.","metaTitle":"Keystone 1640A PCB Pin Socket, Press-Fit, Gold","metaDescription":"Keystone 1640A PCB pin socket, press-fit knurled termination, gold-plated beryllium copper contact, accepts 0.084\" to 0.102\" pin diameter.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","PCB Pin Sockets"],"specifications":{"Mfr":"Keystone Electronics","Series":"-","Package":"Bulk","Features":"-","Tail Type":"No Tail","Termination":"Press-Fit, Knurled","Socket Depth":"0.165\\\" (4.19mm)","Tail Diameter":"-","Contact Finish":"Gold","Product Status":"Active","Board Thickness":"-","Flange Diameter":"0.170\\\" (4.32mm)","Insertion Force":"-","lifecycle_stage":"unknown","Contact Material":"Beryllium Copper","Length - Overall":"0.165\\\" (4.19mm)","Pin Hole Diameter":"-","Accepts Pin Diameter":"0.084\\\" ~ 0.102\\\" (2.13mm ~ 2.59mm)","Operating Temperature":"-","Mounting Hole Diameter":"0.138\\\" (3.50mm)","Accepts Square Pin Size":"-","Contact Finish Thickness":"10.0µin (0.25µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4000","priceTiers":[{"qty":1,"price":"$2.40000","currency":"USD"},{"qty":25,"price":"$2.37560","currency":"USD"},{"qty":100,"price":"$2.33000","currency":"USD"},{"qty":250,"price":"$2.18376","currency":"USD"},{"qty":500,"price":"$1.94000","currency":"USD"},{"qty":1000,"price":"$1.26001","currency":"USD"},{"qty":2500,"price":"$1.17362","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d44843fa0c57bd0e2f510776c73af172.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1640A/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 1640A in this PCB Pin Sockets family?","answer":"No same-series peer is recorded in the parametric data.
