The header carries square male pins with a tin-plated mating surface rated for 5 A per circuit at 110 V, through-hole solder termination, and a black UL94 V-0 housing. This is a board-to-board interconnect, typically used as the pin header half of a pin-and-socket pair on a PCB. The 0.100\" (2.54 mm) pitch sets the pad spacing on the PCB and determines compatibility with standard prototyping boards. The 21-position count is an odd number, so the BOM likely calls for exactly 21 circuits rather than a standard multiple. This is an unshrouded header — it mates with any standard 0.100\" pitch single-row socket strip or IDC receptacle that accepts 0.025\" square pins. Termination is through-hole solder, with a 0.095\" (2.41 mm) post length for the solder tail and a 0.200\" (5.08 mm) mating pin length. The overall contact length is 0.395\" (10.03 mm). The insulation height of 0.100\" (2.54 mm) sets the standoff above the board surface.","metaTitle":"Amphenol BERGSTIK II 68705-421HLF, 21-pos Unshrouded Header","metaDescription":"Amphenol FCI BERGSTIK II 68705-421HLF single-row unshrouded header. 21 positions, 0.100\" (2.54 mm) pitch, 5 A, 110 V, 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":"68705-421HLF","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":"1","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":"68705","Number of Positions":"21","Contact Length - Post":"0.095\\\" (2.41mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.395\\\" (10.03mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.200\\\" (5.08mm)","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":"$2.1406","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/68705-421HLF/alternatives.json"},"ai":{"faq":[{"question":"What connector series does the 68705-421HLF belong to?","answer":"It is a member of the Amphenol FCI BERGSTIK II series, a family of 0.100-inch pitch single-row board-to-board headers in standard and high-temperature glass-filled polyester housings."},{"question":"What is the 68705-421HLF's listed style?","answer":"The listed style is Board to Board — this header is designed for board-to-board stacking rather than wire-to-board harness connections."},{"question":"What is the current and voltage rating per contact?","answer":"Each contact is rated 5 A at 110 V, with tin plating at 100 µin (2.54 µm) thickness on the mating surface."},{"question":"What compliance ratings does the 68705-421HLF carry?","answer":"The housing meets UL94 V-0 flammability.
