It's a through-hole solder part with a push-pull fastening system — no latch, no shroud, just the pins and the housing. The 46 positions are all loaded, giving you a 23-per-side layout on 0.100\" row spacing. This is a general-purpose board-to-board interconnect for parallel signal or moderate I/O density on a standard grid. The 46 positions on dual rows means 23 pins per side; the row spacing is also 0.100\", so the overall footprint is 46 pins on a 0.100\" square grid. The tin-on-tin contact system is fine for a few dozen mate-unmate cycles; if your application needs frequent field service or lives in a corrosive environment, you'd typically step up to gold-plated contacts, but the cost trade-off here is clear. The 0.430\" mating length and 0.200\" tail length are standard for a 0.062\" board thickness with a typical through-hole solder joint.","metaTitle":"Amphenol FCI 79821-446HLF BERGSTIK II Header, 46 Pos","metaDescription":"Amphenol FCI BERGSTIK II 79821-446HLF dual-row unshrouded header, 46 positions, 0.100\" pitch, 5A per circuit at 110V, through-hole solder, tin-plated contacts","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-446HLF","Series":"BERGSTIK® II","Packaging":"Bag","Shrouding":"Unshrouded","Termination":"Solder","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)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"79821","Number of Positions":"46","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","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 - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3164","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-446HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum current rating per pin for 79821-446HLF?","answer":"The 79821-446HLF is rated 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts."},{"question":"Is 79821-446HLF RoHS compliant?","answer":"The part carries tin-plated contacts and a UL94 V-0 black housing, consistent with RoHS-compliant materials.
