It is a through-hole solder-terminated board-to-board interconnect — the mating pins are square, 0.025\" square typical for this class, and the overall contact length measures 0.513\" (13.03 mm) with a mating pin length of 0.230\" (5.84 mm) and a solder tail of 0.183\" (4.65 mm). Rated 5 A per contact at a voltage rating of 110 V, the header carries 30.0 µin (0.76 µm) of gold or Gold GXT plating on the mating surface — enough for repeated mating cycles in a production or field-service environment. The 0.100\" (2.54 mm) pitch is the bread-and-butter spacing for through-hole headers — it matches the legacy perf-board and prototyping grid, and the footprint is a standard 0.100\" row of plated through-holes. The insulation height above the board is 0.100\" (2.54 mm), with pins protruding 0.230\" (5.84 mm) above the housing for mating. The solder tail length of 0.183\" (4.65 mm) is sized for a standard PCB thickness, giving enough protrusion through the board for a reliable solder fillet.","metaTitle":"Amphenol FCI BERGSTIK II 68031-126HLF, 26-Pin Header","metaDescription":"Amphenol FCI BERGSTIK II 68031-126HLF unshrouded male header, 26 circuits, 0.100\" (2.54 mm) pitch, 5 A per contact, 30.0 µin gold plating, 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":"68031-126HLF","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":"68031","Number of Positions":"26","Contact Length - Post":"0.183\\\" (4.65mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.513\\\" (13.03mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1386","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/68031-126HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pin length (mating height) of 68031-126HLF?","answer":"The contact length on the mating side is 0.230\" (5.84 mm), and the overall contact length from the top of the pin to the tip of the solder tail is 0.513\" (13.03 mm).
