This single-row, through-hole solder header carries tin-plated phosphor bronze contacts rated 5 A per circuit at 110 V, with a 100.0 µ\" (2.54 µm) tin mating finish. The black UL94 V-0 thermoplastic housing and push-pull fastening make it a straightforward board-to-board interconnect for low-cycle, cost-sensitive applications where the mating receptacle is aligned by the PCB layout rather than a shroud. ## Deployment context The unshrouded design means the header relies entirely on the PCB layout and the mating receptacle's alignment features to prevent mis-mating — there is no polarization key or shroud wall to block a reversed or offset plug. The through-hole solder termination and UL94 V-0 housing suit it for equipment inside an enclosure where flame rating is required, such as industrial control boards, test fixtures, or low-cost peripheral interconnects. The 0.095\" (2.41mm) solder post length is short enough for standard 1.6 mm PCBs without bottom-side clearance issues.","metaTitle":"Amphenol FCI 87185-429HLF BERGSTIK II Header, 29-Pos","metaDescription":"Amphenol FCI BERGSTIK II 87185-429HLF, 29-position unshrouded male header, 0.100\" (2.54mm) pitch, 5 A at 110 V, through-hole solder, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"87185-429HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"87185","Number of Positions":"29","Contact Finish - Post":"Tin","Contact Length - Post":"0.095\\\" (2.41mm)","Current Rating (Amps)":"5A","Overall Contact Length":"1.238\\\" (31.45mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"1.043\\\" (26.49mm)","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":"$3.4774","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87185-429HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pin count of 87185-429HLF?","answer":"The 87185-429HLF has 29 positions, all loaded, in a single row."},{"question":"Does 87185-429HLF have a shroud?","answer":"No, the 87185-429HLF is an unshrouded header — there is no shroud wall or polarization key.
