Tin-plated contacts are cost-effective for low-cycle applications — expect a few hundred mates before wear-through, not the thousands a gold flash would deliver. The 0.025\" square pins are standard for wire-to-board crimp receptacles and IDC sockets — any industry-standard 0.100\" pitch female housing with 0.025\" square receptacles will mate. No secondary lock or TPA is present; retention relies on the interference fit of the pin into the receptacle.","metaTitle":"77311-424-23LF BERGSTIK® Header, 23 Pos, 0.100\" Pitch","metaDescription":"77311-424-23LF Amphenol ICC (FCI) BERGSTIK® board-to-board header, 23 positions, single row, 0.100\" pitch, tin-plated, through hole, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"77311","Insulation Material":"Thermoplastic","Number of Positions":"23","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.114\\\" (2.90mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.480\\\" (12.19mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.266\\\" (6.75mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"78.7µin (2.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 77311-424-23LF?","answer":"Common choices include industry-standard IDC receptacles or crimp-type socket housings from the same BERGSTIK® series or compatible third-party lines.
