The 3 A per-contact current rating is conservative for tin at 25 °C; derate above 85 °C ambient per the standard curve. The base product number is 77313; the -452-20LF suffix specifies the 20-position, dual-row, tin-plated variant. No official pin-compatible replacement has been announced — if you need a shrouded or gold-plated version, look at other BERGSTIK® order codes in the same 0.100\" pitch family.","metaTitle":"77313-452-20LF BERGSTIK® Header, 20-Pin, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 77313-452-20LF BERGSTIK® unshrouded header, 20 positions, 0.100\" pitch, 3 A per contact, tin plating, 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 or Cable","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","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":"77313","Insulation Material":"Thermoplastic","Number of Positions":"20","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"0.594\\\" (15.09mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.374\\\" (9.50mm)","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":"$1.1303","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of the 77313-452-20LF header?","answer":"The mating pitch is 0.100\" (2.54 mm), and the row spacing is also 0.100\" (2.54 mm).
