It uses a 0.100\" (2.54mm) pitch in a dual-row layout, with all 42 positions loaded. The right-angle through-hole termination places the pins parallel to the PCB, suited for edge-mount or space-constrained layouts where the mating axis runs along the board surface. Rated 5 A per contact with a 110 V voltage rating, the header carries enough current for signal and moderate power duty on a standard 0.100\" grid. The tin-on-tin contact finish (100.0 µin on the mating side) is a workhorse choice for cost-sensitive, low-mating-cycle applications — tin wipes clean on first insertion but frets under vibration if the pair is not locked. The UL94 V-0 black housing meets the flammability requirement for equipment inside an enclosure. ## Mating and Termination As an unshrouded header with push-pull fastening, this connector mates with any standard 0.100\" pitch dual-row receptacle that accepts 0.025\" square pins — no keying, no latch, so the pair relies on the receptacle's own retention (friction or a separate locking ramp). The 0.160\" (4.06mm) mating pin length gives enough wipe for a typical box-header or IDC socket. The 0.120\" (3.05mm) solder post length suits standard 0.062\" to 0.093\" PCBs. Termination is solder-only — through-hole for the pins, no press-fit option. The square pin profile (0.025\" square) is the industry-standard geometry for this pitch class, compatible with most dual-row crimp or insulation-displacement receptacles on the market. ## Sourcing and Lifecycle The 93939-442HLF carries an Active lifecycle status — full production, no end-of-life notice on record. No official replacement or cross-reference is listed, so the BOM line stays with this exact order code.","metaTitle":"FCI 93939-442HLF BERGSTIK II Header, 42 Pos, 0.100\" Pitch","metaDescription":"93939-442HLF BERGSTIK II unshrouded header, 42 positions, 0.100\" pitch, dual-row, right-angle through-hole, tin-plated, 5 A, 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, Right Angle","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":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"93939","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":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.160\\\" (4.06mm)","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/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-442HLF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 93939-442HLF?","answer":"Contact the storefront with your BOM for a same-day quote."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-442HLF","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/93939-442HLF when reusing this data.
