Rated at 5A per contact with a 110V voltage ceiling, it suits internal board-to-board wiring where the current draw per line stays under the 5A limit and the board stack-up accommodates the 0.730\" (18.54mm) overall contact length. The phosphor bronze base alloy provides adequate spring retention for the push-pull fastening. The through-hole termination with a 0.200\" (5.08mm) post length gives a solid mechanical anchor through the board, and the UL94 V-0 rated black insulation suits equipment installed inside an enclosure requiring a flame-rated component. This 36-position dual-row header sits at the higher end of the BERGSTIK® II position count range. At the same 0.100\" pitch and with the same tin-plated contacts, a 10-position sibling (79821-410HLF) serves low-circuit-count signal runs, while this 36-position version fills a board edge or mezzanine position that needs more I/O lines without moving to a denser pitch. The decision between them is strictly circuit count — the footprint pattern scales linearly, and the electrical ratings are identical across the family. The push-pull retention means the mating connector's own friction and latch (if present) hold the pair together — there is no header-side locking feature. The through-hole solder tails are designed for wave or hand-solder assembly — no press-fit option on this order code.","metaTitle":"Amphenol 79821-436HLF BERGSTIK II Header, 36 Pos, 2.54mm","metaDescription":"Amphenol 79821-436HLF BERGSTIK® II unshrouded header, 36 positions, dual-row 0.100\" pitch, 5A, tin-plated contacts, 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® II","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":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"79821","Insulation Material":"-","Number of Positions":"36","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"0.730\\\" (18.54mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.430\\\" (10.92mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-436HLF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 79821-436HLF and what is the lead time?","answer":"The 79821-436HLF is sourced and quoted to order through independent distribution — current pricing and lead time are confirmed at quote time against your BOM quantity.
