This is the all-positions-loaded variant, so the circuit count matches the position count exactly: 50 circuits in two rows, each contact a square male pin of phosphor bronze with a 100.0 µ\" (2.54 µm) tin finish on the mating surface and tin on the solder post. The through-hole termination with a 0.120\" (3.05 mm) post length suits standard PCB thicknesses, and the 0.100\" (2.54 mm) row spacing keeps the routing density predictable. Within the BERGSTIK® II family, the 50-position 87052-450HLF sits at the higher end of the position range — a dual-row header with all 50 contacts loaded. The footprint, row spacing, and mating receptacle family are identical, so a board layout designed for a lower position count cannot simply drop in the 50-position without adding more plated through-holes. No other functional difference — same 5 A rating, same tin plating, same overall contact length of 0.990\" (25.15 mm). As an unshrouded header, the 87052-450HLF mates with any standard 0.100\" (2.54 mm) pitch dual-row receptacle — typically an IDC socket or a crimp-style housing with the matching square-pin contact geometry. For a board-to-board stack, the overall contact length of 0.990\" (25.15 mm) with a 0.770\" (19.56 mm) mating length gives the designer the mated stack height budget.","metaTitle":"Amphenol BERGSTIK II 87052-450HLF Header, 50 Pos","metaDescription":"Amphenol BERGSTIK® II 87052-450HLF unshrouded header, 50 positions, 0.100\" (2.54mm) pitch, dual-row, through-hole, 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":"2","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":"87052","Insulation Material":"-","Number of Positions":"50","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"0.990\\\" (25.15mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.770\\\" (19.56mm)","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":"$4.8974","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87052-450HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 87052-450HLF?","answer":"The 87052-450HLF has a 0.100\" (2.54 mm) mating pitch — the standard industry grid for this class of pin header, compatible with a wide range of 0.100\" pitch receptacles."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/87052-450HLF","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/87052-450HLF when reusing this data.
