The contacts are tin-plated phosphor bronze, rated 5 A per circuit at 110 V, with a 100.0 µin (2.54 µm) tin finish on the mating surface. The dual-row layout with 0.100-inch (2.54 mm) row spacing means the 26 positions occupy a 13 x 2 hole pattern that matches standard 0.100-inch IDC ribbon-cable receptacles and many generic wire-to-board housings. At 110 V, the 0.100-inch pitch provides adequate creepage for signal-level voltages in dry indoor environments. ## Board-to-board use The listed style is Board to Board, and the 0.160-inch (4.06 mm) mating pin length gives enough engagement depth for standard 0.100-inch pitch receptacles. The right-angle orientation limits this to mezzanine or perpendicular stacking — the header sits on one board and the mating receptacle on a parallel or perpendicular board, with the mated height determined by the receptacle's insulation height.","metaTitle":"Amphenol BERGSTIK II 93939-426HLF, 26-pos 2.54mm Header","metaDescription":"Amphenol BERGSTIK II 93939-426HLF, 26-position dual-row unshrouded header, 0.100\" (2.54 mm) pitch, 5 A, 110 V, right-angle through-hole, 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":"93939-426HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","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":"0.190\\\" (4.83mm)","Base Product Number":"93939","Number of Positions":"26","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.160\\\" (4.06mm)","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":"$4.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-426HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 93939-426HLF?","answer":"The pitch is 0.100 inch (2.54 mm) on both the mating and row spacing, which is the standard breadboard-compatible grid."},{"question":"Is 93939-426HLF unshrouded?","answer":"Yes, it is an unshrouded header — no keying or polarization.
