It uses tin-plated phosphor bronze square pins, through-hole solder termination, and a push-pull fastening interface. This is a basic, no-frills pin header — the kind you grab when you need a reliable signal interconnect on a breadboard-compatible grid, not a shrouded or keyed connector for high-vibration environments. The 0.100\" (2.54 mm) pitch and 0.100\" row spacing are the classic DIP/IC footprint — this header drops into standard perfboard or a 0.100\"-grid PCB layout without a custom footprint.","metaTitle":"Amphenol BERGSTIK II 79821-406HLF, 6-pos 2.54mm Header","metaDescription":"Amphenol BERGSTIK II 79821-406HLF, 6-position dual-row unshrouded header, 0.100\" (2.54 mm) pitch, tin-plated contacts rated 5 A, 110 V, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-406HLF","Series":"BERGSTIK® II","Package":"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":"6","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":"$1.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-406HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 79821-406HLF?","answer":"The pitch is 0.100\" (2.54 mm) on both the pin spacing and the row spacing — standard breadboard-compatible grid."},{"question":"Is 79821-406HLF shrouded?","answer":"No, it is an unshrouded header — no plastic shroud around the pins.
