It carries tin-plated phosphor bronze male pins rated 5 A per circuit at 110 V, terminated by through-hole solder into a black UL94 V-0 housing. This is a board-to-board interconnect — the unshrouded design leaves the pins exposed for direct mating with a receptacle or for use as a programming/test header, common in industrial control, telecom line cards, and embedded computing where the 0.100\" grid matches legacy PCB layouts. ## What the ratings mean for the fit The 0.100\" (2.54 mm) pitch is the de facto standard for 0.1-inch grid prototyping and production boards — the footprint is a 20-pin dual-row pattern with 0.100\" row spacing, so the board layout is straightforward if the existing pattern matches. The 5 A per circuit rating is typical for this pitch and contact size; the limiting factor in practice is the temperature rise through the tin-plated interface, so derate above 25 °C ambient. Tin-on-tin mating finish (100.0 µin on the mating side) is cost-effective for one-time assembly or low-cycle applications — it wears faster than gold under repeated mating, so if the board sees field-service reconnects, consider a gold-plated variant in the same series.","metaTitle":"Amphenol FCI 67998-420HLF BERGSTIK II Header, 20 Pos","metaDescription":"Amphenol FCI 67998-420HLF BERGSTIK II unshrouded header, 20 positions, 0.100\" (2.54 mm) pitch, tin-plated contacts rated 5 A at 110 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"67998-420HLF","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":"67998","Number of Positions":"20","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.107\\\" (2.71mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.525\\\" (13.34mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.318\\\" (8.08mm)","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":"$0.6608","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/67998-420HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 67998-420HLF?","answer":"The pitch is 0.100\" (2.54 mm) on both the mating interface and the row spacing."},{"question":"Is 67998-420HLF shrouded?","answer":"No, it is an unshrouded header — the pins are exposed for direct mating or probing."},{"question":"What is the current rating of 67998-420HLF?","answer":"The header is rated 5 A per circuit at 110 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/67998-420HLF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/67998-420HLF when reusing this data.
