Rated 5 A per circuit at 110 V, with 30.0 µ\" gold or GXT plating on the mating surface — a plating grade that handles repeated mating cycles without the contact resistance drift you get from thin flash or tin. The 0.100\" (2.54mm) pitch is the key footprint match — it aligns with standard perfboard, prototyping grids, and the matching IDC socket or crimp receptacle. The 21-position count is the BOM line; single row keeps the board footprint narrow. If your application sees frequent board swaps or field service, this plating holds up.","metaTitle":"Amphenol FCI 87916-121HLF BERGSTIK II Header, 21 Pos","metaDescription":"Amphenol FCI 87916-121HLF BERGSTIK II unshrouded male header, 21 positions, single row, 0.100\" pitch, 5 A, 110 V, 30 µ\" gold.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"87916-121HLF","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":"87916","Number of Positions":"21","Contact Length - Post":"0.128\\\" (3.25mm)","Current Rating (Amps)":"5A","Overall Contact Length":"1.058\\\" (26.87mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.830\\\" (21.08mm)","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":"$2.1406","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87916-121HLF/alternatives.json"},"ai":{"faq":[{"question":"How many pins does 87916-121HLF have and what is the pitch?","answer":"The 87916-121HLF has 21 positions in a single row at a 0.100\" (2.54mm) pitch."},{"question":"Is the 87916-121HLF shrouded or unshrouded?","answer":"The 87916-121HLF is an unshrouded header — no polarization keying, so the mating receptacle requires manual alignment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/87916-121HLF","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/87916-121HLF when reusing this data.
