The base product number is 77315; the -824-21LF suffix encodes the plating and packaging variant. No pin-compatible direct replacement is listed by the manufacturer — if you need a second source, look for other BERGSTIK® single-row 21-position right-angle headers with gold plating and verify the mating pin length matches your socket. ## Material and Compliance Notes Phosphor bronze contacts provide a good balance of spring retention and corrosion resistance for signal-level currents. The square pin profile mates with standard square-pin socket contacts.","metaTitle":"77315-824-21LF BERGSTIK® Header — 21 Pos, 2.54mm","metaDescription":"Amphenol ICC (FCI) 77315-824-21LF: 21-position single-row unshrouded breakaway header, 0.100\" pitch, through-hole right-angle, gold-plated mating contacts.","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, Right Angle","Connector Type":"Header, Breakaway","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":"0.094\\\" (2.40mm)","Ingress Protection":"-","Base Product Number":"77315","Insulation Material":"Thermoplastic","Number of Positions":"21","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.112\\\" (2.84mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3940","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/afff082a78752745a1d7e124ea6d740f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 77315-824-21LF and get a price?","answer":"No stock-holding claim is made; each order is sourced fresh."},{"question":"What is the pin configuration of 77315-824-21LF?","answer":"All positions are loaded.
