Rated 5A per circuit at 110V, with 30.0µin (0.76µm) gold plating on the mating surface — the gold thickness supports repeated mating cycles without the contact fretting you would see with tin on a frequently disconnected line. Within the BERGSTIK® II family, the 28-position 87901-128HLF sits between the 20-position and 36-position variants at the same 0.100\" pitch and dual-row layout. The selection decision is purely the circuit count matching the BOM — the footprint, current rating, and plating grade are consistent across the loaded-position range. Termination is through-hole solder — the 0.120\" (3.05mm) post length suits standard PCB thicknesses from 0.062\" to 0.093\".","metaTitle":"Amphenol FCI 87901-128HLF BERGSTIK II Header, 28-Pos","metaDescription":"Amphenol FCI 87901-128HLF BERGSTIK® II unshrouded header, 28 positions dual-row, 0.100\" (2.54mm) pitch, 5A, gold 30µin contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"87901-128HLF","Series":"BERGSTIK® II","Packaging":"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":"2","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":"87901","Number of Positions":"28","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Overall Contact Length":"1.040\\\" (26.42mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.820\\\" (20.83mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7387","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87901-128HLF/alternatives.json"},"ai":{"faq":[{"question":"What mates with the 87901-128HLF?","answer":"This unshrouded header mates with any 0.100\" (2.54mm) pitch dual-row female socket header or IDC receptacle that accepts 0.025\" square pins.
