The 42 circuits are fully loaded across two rows, with a row-to-row spacing of 0.100 inch (2.54 mm), keeping the footprint on a simple 0.100-inch grid for board layout. The limiting factor here is the tin-on-tin contact interface — 100 µinch (2.54 µm) tin plating on the mating surface is a heavy wipe-grade finish that handles 25 to 50 mating cycles without fretting corrosion, but it is not built for frequent reconnection. For a permanent or semi-permanent board-to-wire or board-to-board link inside an enclosure, that is fine. The 110 V voltage rating matches the clearance and creepage of the 0.100-inch pitch on a standard FR-4 board. The UL94 V-0 black housing means it is rated for flame retardancy inside equipment enclosures. This is a through-hole solder header — the 0.120 inch (3.05 mm) solder tail length suits standard 0.062-inch (1.6 mm) PCBs. The overall contact length is 0.470 inch (11.94 mm), with a 0.250 inch (6.35 mm) mating pin length that engages with standard 0.100-inch pitch receptacles.","metaTitle":"Amphenol FCI 86503-442HLF BergStik II Header, 42-Pos","metaDescription":"Amphenol FCI BergStik II 86503-442HLF, 42-position dual-row unshrouded male pin header, 0.100\" (2.54mm) pitch, 5A, tin-plated, 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":"86503-442HLF","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":"86503","Number of Positions":"42","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.470\\\" (11.94mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.250\\\" (6.35mm)","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":"$4.1883","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/86503-442HLF/alternatives.json"},"ai":{"faq":[{"question":"How many positions does 86503-442HLF have?","answer":"The 86503-442HLF has 42 positions, fully loaded across two rows at 0.100 inch (2.54 mm) pitch."},{"question":"What is the closest pin-compatible alternative to 86503-442HLF in this component family?","answer":"Within the BergStik II series, the closest pin-compatible alternative is another 42-position dual-row unshrouded header on the same 0.100-inch pitch with matching pin lengths.
