The right-angle, through-hole mounting orientation places the mated board parallel to the carrier board, which is the typical arrangement for mezzanine or expansion card connections where height clearance is tight. ## Key Electrical and Mechanical Ratings Each tin-plated phosphor bronze contact is rated for 5 A. ## Tin-Plated Contacts and Mating Cycles Tin is the workhorse plating for connectors that mate a few times in their service life — it forms a hard, self-cleaning oxide layer that breaks through on wipe during insertion. ## Mechanical Fit and Board Layout The base product number is 86840, which covers the dual-row, 0.100\" pitch BergStik II header family.","metaTitle":"Amphenol 86840-466HLF BergStik II Header, 66 Pos","metaDescription":"Amphenol BergStik® II 86840-466HLF unshrouded header, 66 positions, 2 rows, 0.100\" (2.54mm) pitch, right-angle through-hole, tin-plated contacts, 5A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK® II","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","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)","Product Status":"Active","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"86840","Insulation Material":"-","Number of Positions":"66","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.230\\\" (5.84mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","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 - Post":"-","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8543","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/86840-466HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 86840-466HLF?","answer":"Each contact is rated for 5 A.
