Rated at 5A per contact and 110V, this header suits low-power signal or control circuits where the board-to-board distance is set by the 1.043\" (26.49mm) mating contact length. The 0.100\" (2.54mm) pitch is the key footprint parameter — it matches standard 0.1-inch grid protoboards and many legacy PCB layouts. The actual current limit in a real assembly depends on the number of adjacent pins carrying current simultaneously and the ambient temperature — derate per the manufacturer's curve if running all pins at 5A in a warm enclosure. Tin-on-tin contact interface means this header is best for one-time or occasional disconnect duty. For applications requiring frequent mating cycles or operation in corrosive environments, a gold-plated BergStik variant would be the correct choice. As an unshrouded header, the 87185-402HLF mates with standard 0.100\" pitch female socket housings or IDC receptacles that accept the 0.025\" square pin. The push-pull retention relies entirely on the contact friction of the mating half — no latch or locking ramp is present on the header itself. Termination is through-hole solder. The 0.095\" (2.41mm) post length is suited for standard 0.062\" (1.6mm) PCBs with through-hole plating. The overall contact length of 1.238\" (31.45mm) includes the 1.043\" (26.49mm) mating section and the solder tail.","metaTitle":"FCI 87185-402HLF BergStik II Header, 2-Pos, 0.100\" Pitch, 5A","metaDescription":"FCI 87185-402HLF BergStik II unshrouded header, 2 positions, 0.100\" (2.54mm) pitch, tin-plated contacts rated 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","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"87185","Insulation Material":"-","Number of Positions":"2","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.095\\\" (2.41mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","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 - Post":"-","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87185-402HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pin configuration of 87185-402HLF?","answer":"The 87185-402HLF is a single-row, 2-position unshrouded header with all positions loaded.
