It uses square male pins with tin plating on both the mating surface and the solder posts — 100.0 µin (2.54 µm) on the mating side, which is a healthy thickness for a tin finish and will hold up to a reasonable number of insertion cycles in a controlled environment. Rated at 5 A per circuit with a 110 V voltage rating, this header sits in the general-purpose signal range — fine for powering logic boards, driving relays, or carrying low-current loads where the 0.100\" pitch gives enough creepage for the voltage without forcing a wide board footprint. ## What the Tin Plating Means for Your Application The 100.0 µin tin-on-phosphor-bronze contact finish is a workhorse choice for cost-sensitive, low-mating-cycle designs. Tin is softer than gold and will oxidize over time, but the thickness here is well above flash-plating levels — it will survive dozens of insertions without fretting if the connector is mated in a clean, dry environment.","metaTitle":"Amphenol BERGSTIK II 87185-418HLF, 18-pos 0.100\" header, 5 A","metaDescription":"Amphenol BERGSTIK II 87185-418HLF board-to-board header, 18 positions, 0.100\" (2.54mm) pitch, single row, 5 A, tin-plated contacts, 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":"87185-418HLF","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":"18","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":"$1.4764","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87185-418HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of the 87185-418HLF?","answer":"Rated 5 A per circuit at the stated voltage of 110 V.

The '-HLF' variant carries a tin-plated mating finish; the '-LF' variant is a lead-free (RoHS) version. Verify the specific plating and RoHS compliance against your BOM requirements before ordering."},{"question":"Is the 87185-418HLF RoHS compliant?","answer":"The product description does not explicitly state RoHS compliance, but the tin plating and phosphor bronze contact material are typical of RoHS-compliant designs.
