The 0.100\" (2.54mm) pitch is the standard square-grid footprint, so the board layout matches any legacy 0.100\" pattern. Rated 5A per circuit at 110V, with gold or Gold GXT™ plating at 30µin (0.76µm) on the mating surface — the plating grade supports repeated mating cycles without contact fretting, a common failure in tin-plated headers under vibration. The 42 positions, all loaded, match a 42-circuit BOM line exactly — no depopulated rows to track. The 0.100\" pitch drives the board footprint: each pin lands on a 0.100\" grid, and the dual-row layout with 0.100\" row spacing means the through-hole pattern occupies a 0.100\" × 0.100\" matrix. That's a standard footprint shared across the BergStik II family, so a layout drawn for a 40-position header in the same series takes the same pad pattern — just shorter. Right-angle through-hole termination: the pins exit the body and bend 90°, so the connector sits flush against the board edge with the pin tips extending 0.230\" (5.84mm) past the board underside. The mating pin length is 0.318\" (8.08mm) — long enough to engage a standard box-header or IDC receptacle with a 0.190\" (4.83mm) insulation height.","metaTitle":"Amphenol FCI 86840-142HLF BergStik II Header, 42 Pos","metaDescription":"Amphenol FCI BergStik II 86840-142HLF unshrouded male header, 42 positions, 0.100\" pitch, right-angle through-hole, 5A, 110V, gold plating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"86840-142HLF","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":"86840","Number of Positions":"42","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.230\\\" (5.84mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.318\\\" (8.08mm)","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":"$4.1883","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/86840-142HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 86840-142HLF?","answer":"No official cross-reference or direct replacement is listed.
