Tin-plated square pins on 0.100\" (2.54 mm) pitch carry 3 A per contact. The through-hole solder termination and push-pull fastening suit it for parallel-board spacing where a shrouded header would block airflow. ## Pitch, plating, and pin count The 0.100\" (2.54 mm) pitch and tin-on-tin contact system keep per-contact cost low for high-density signal routing. The single row of 32 positions loads all positions; the unshrouded profile mates with standard 0.100\" pitch receptacles without keying. ## Thermoplastic housing and flammability Black thermoplastic insulator carries UL94 V-0 rating. The operating range spans -65°C to 125°C, covering most industrial and telecom enclosures without derating.","metaTitle":"Amphenol BERGSTIK 77311-424-32LF Header, 32-Pos 2.54mm","metaDescription":"Amphenol ICC (FCI) BERGSTIK header 77311-424-32LF: 32 positions, single row, 2.54 mm pitch, 3 A per contact, tin-plated mating contacts, through-hole solder","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":"32","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":"$1.8783","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77311-424-32LF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 77311-424-32LF in this Pin Headers, Sockets & Housings family?","answer":"No pin-compatible alternative is listed in the same BERGSTIK® series.
