It uses a standard 0.100\" (2.54 mm) pitch in a dual-row layout, with all positions loaded. The through-hole, right-angle mounting orients the pins parallel to the PCB, suiting board-edge or space-constrained layouts where the mating axis runs along the board surface. Rated 5 A per contact with a 110 V voltage rating, it handles signal-level and moderate power duty. The mating contacts carry 30.0 µin (0.76 µm) gold or Gold GXT™ plating, which provides corrosion resistance and supports repeated mating cycles in field-service or industrial environments. ## Key Specs & What They Mean for Your Build The 0.100\" pitch is a de facto standard for prototyping and production boards — it matches the grid of most perfboards and the pad layout of many IDC receptacles. The 66 positions give you a high-density connection for parallel data or address buses, or for grouping multiple I/O signals into one connector. The right-angle orientation means the header sits flush against the board edge, so the mating receptacle plugs in parallel to the PCB — useful when vertical clearance is tight. The 30.0 µin gold on the mating surface is a robust plating grade: it handles hundreds of mating cycles without oxidation, making this header a good fit for modules that get swapped during testing or field maintenance. The UL94 V-0 housing is standard for equipment inside an enclosure where flame rating is required.","metaTitle":"68405-166HLF Amphenol BERGSTIK II Header, 66 Pos","metaDescription":"68405-166HLF Amphenol BERGSTIK II unshrouded header, 66 positions, 0.100\" pitch, 5 A, gold/GXT plating, through-hole right-angle.","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":"68405","Insulation Material":"-","Number of Positions":"66","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"-","Contact Length - Post":"0.095\\\" (2.41mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","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/68405-166HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 68405-166HLF?","answer":"The mating pitch is 0.100\" (2.54 mm), which is the standard 0.100-inch grid for through-hole headers."},{"question":"What is the mounting type of 68405-166HLF?","answer":"It is a through-hole, right-angle mount header — the pins are soldered into plated through-holes and the connector body sits at a right angle to the PCB."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/68405-166HLF","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/68405-166HLF when reusing this data.
