Rated at 5 A per circuit, the current capacity is typical for a 0.100\" pitch header — enough for signal-level loads and light power distribution, but not a main power rail. The mating contacts carry a gold or GXT finish at 30.0 µin (0.76 µm) thickness, which supports repeated mating cycles without the contact resistance drift you see with tin-on-tin interfaces. The square pins measure 0.160\" (4.06 mm) on the mating side and 0.120\" (3.05 mm) on the solder tail. The right-angle through-hole termination requires the board to have a matching 2-row, 66-position through-hole pattern at 0.100\" pitch. No secondary retention features; the friction of the pin-socket interface holds the mated pair.","metaTitle":"Amphenol FCI 93939-166HLF BERGSTIK II Header, 66 pos","metaDescription":"Amphenol FCI BERGSTIK II 93939-166HLF, 66-position dual-row board-to-board header, 0.100\" (2.54 mm) pitch, right-angle through-hole, 5 A, gold mating contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"93939-166HLF","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":"93939","Number of Positions":"66","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.160\\\" (4.06mm)","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":"$5.8543","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-166HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 93939-166HLF?","answer":"The pitch is 0.100\" (2.54 mm) on both the mating interface and the row spacing."},{"question":"How many pins does 93939-166HLF have?","answer":"It has 66 positions in a dual-row configuration, all loaded."},{"question":"What is the mating connector for 93939-166HLF?","answer":"This unshrouded male pin header mates with any standard 0.100\" pitch female socket strip or IDC receptacle with 66 positions in a dual-row layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-166HLF","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/93939-166HLF when reusing this data.
