It is a through-hole, right-angle male pin header designed for board-to-board interconnect applications where a low-profile, unshrouded interface is acceptable. The 0.100\" row spacing mirrors the pitch, so the footprint matches a standard 0.100\" grid — no custom pad layout needed for prototyping or production boards. The 0.160\" (4.06 mm) mating pin length provides enough engagement depth for standard BERGSTIK receptacles without bottoming out in the mating housing. The 5 A rating is typical for a 0.100\" pitch tin-plated contact; derate above 25 °C ambient per the manufacturer's curve. The tin-on-tin mating interface with 100 µ\" (2.54 µm) of tin on the mating side is a heavy-duty plating for moderate mating cycles — expect several hundred mates before wear-through, but not the thousands a gold-plated contact would deliver. Tin is cost-effective for internal connections that stay mated for the life of the assembly. The 0.120\" (3.05 mm) solder tail length is standard for a 0.062\" board thickness; for thicker boards, confirm the tail protrudes enough for a reliable solder fillet. The 0.190\" (4.83 mm) insulation height keeps the pin base above the board, allowing clearance for traces or components under the header body.","metaTitle":"Amphenol BERGSTIK II 93939-410HLF Header, 10 Pos","metaDescription":"BERGSTIK® II unshrouded header, 10 positions, 0.100\" pitch, dual-row, right-angle through-hole, tin-plated contacts rated 5 A.","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":"93939","Insulation Material":"-","Number of Positions":"10","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.160\\\" (4.06mm)","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":"$2.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-410HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 93939-410HLF?","answer":"The mating pitch is 0.100\" (2.54 mm), with the same 0.100\" row spacing — a standard 0.100\" grid footprint."},{"question":"How many rows does the 93939-410HLF have?","answer":"It is a dual-row header — 10 positions arranged in two rows of five."},{"question":"Is the 93939-410HLF shrouded or unshrouded?","answer":"It is an unshrouded header — no plastic shroud around the pins, so the mating receptacle must provide its own alignment and polarization."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-410HLF","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/93939-410HLF when reusing this data.
