It uses the industry-standard 0.100\" (2.54mm) pitch on both rows and between rows, making it footprint-compatible with a wide range of legacy through-hole layouts and IDC ribbon-cable receptacles. Rated 5A per contact at 110V, this header carries signal-level to light-power duty — enough for logic-level distribution, GPIO bussing, or low-current peripheral power, but not a bus-bar replacement. The tin-on-tin contact finish (100.0µin on the mating side) keeps unit cost low, though it limits mating-cycle life compared to gold-plated alternatives; for a one-time board-stacking assembly or low-cycle field service, it is a cost-effective choice. The housing is molded from UL94 V-0 rated material, satisfying the flammability requirement for equipment installed inside an enclosure. The push-pull fastening type and unshrouded design mean the header relies on the mating receptacle's retention features — no secondary locking latch on this half. ## Mating and Termination This is the male pin header half of a board-to-board interconnect. It mates with a 42-position, 0.100\" pitch dual-row receptacle housing (such as the BERGSTIK II socket strip series). Termination is through-hole solder — the 0.120\" (3.05mm) solder tail length suits standard 0.062\" to 0.093\" PCB thickness. The 0.770\" (19.56mm) mating pin length provides ample wipe for reliable contact in stacked-board assemblies.","metaTitle":"87052-442HLF BERGSTIK II Header, 42 Pos, 0.100\" Pitch, 5A","metaDescription":"Amphenol/FCI BERGSTIK® II unshrouded header, 42 positions, 2 rows, 0.100\" (2.54mm) pitch, through-hole solder, tin finish, 5A, UL94 V-0.","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":"42","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":"$4.1883","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87052-442HLF/alternatives.json"},"ai":{"faq":[{"question":"What connector mates with 87052-442HLF?","answer":"This unshrouded male pin header mates with a 42-position, 0.100\" pitch dual-row receptacle socket strip — typically another BERGSTIK II series part with matching position count and pitch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/87052-442HLF","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/87052-442HLF when reusing this data.
