Each tin-plated phosphor bronze contact is rated 5A at 110V. The 100.0µin (2.54µm) tin plating on the mating surface is standard for moderate-cycle applications — it handles assembly and occasional rework but isn't specced for frequent field disconnect. ## Mating and footprint This unshrouded header mates with any standard 0.100\" (2.54mm) pitch female socket strip or IDC receptacle — no keying or polarization, so the mating half must be oriented correctly during assembly. The 0.318\" (8.08mm) mating pin length provides good wipe length for reliable contact even with a slightly misaligned receptacle. The 0.190\" (4.83mm) insulation height above the board leaves clearance for the mating housing to seat fully. The right-angle through-hole footprint requires the PCB to have plated holes at the standard 0.100\" (2.54mm) grid. The 0.230\" (5.84mm) post length is typical for a 1.6mm board — it protrudes enough for a solid solder fillet without bottoming out against the board edge. No board locks or alignment pegs, so the header relies on the solder joints for mechanical retention.","metaTitle":"Amphenol FCI BergStik II 86840-404HLF, 4-Pin 2.54mm Header","metaDescription":"Amphenol FCI 86840-404HLF BergStik II unshrouded header, 4 positions, 0.100\" (2.54mm) pitch, right-angle through-hole, tin-plated contacts rated 5A at 110V","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"86840-404HLF","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":"4","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.230\\\" (5.84mm)","Current Rating (Amps)":"5A","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":"$0.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/86840-404HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating per pin for 86840-404HLF?","answer":"Each tin-plated contact is rated 5A at 110V.
