It's a through-hole solder-terminated male pin header with tin-plated phosphor bronze contacts rated for 5 A per circuit at 110 V. The breakaway construction means the 34-pin strip can be snapped to a shorter length if the BOM calls for fewer positions — though this variant ships fully loaded with all 34 positions. The unshrouded design leaves the pins exposed, so the mating receptacle must be aligned by the board layout rather than a keying shroud. ## What the ratings mean for the board fit The 0.100\" pitch is the classic PC-board grid — it matches standard perf-board, legacy prototype boards, and many existing footprints. The 5 A per-contact rating is typical for signal-level interconnects; the tin plating (150.0 µin on the mating surface) is cost-effective for applications with limited mating cycles, but if the design calls for frequent disconnect-reconnect cycles, a gold-plated sibling in the BERGSTIK family would be the better call. The UL94 V-0 thermoplastic housing means the header is rated for equipment inside an enclosure requiring flame retardance. ## Sourcing and lifecycle The 75844-318-34LF carries an Active lifecycle status — full production, no end-of-life notice on record. There is no official successor or cross-reference on record, so confirm the BOM position count and the mating half before committing.","metaTitle":"Amphenol BERGSTIK 75844-318-34LF, 34-Pin Breakaway Header","metaDescription":"Amphenol BERGSTIK 75844-318-34LF dual-row unshrouded breakaway header, 34 positions, 0.100\" pitch, 5 A, tin-plated contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board or Cable","title":"75844-318-34LF","Series":"BERGSTIK®","Package":"Bulk","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","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":"75844","Insulation Material":"Thermoplastic","Number of Positions":"34","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-65°C~130°C","Overall Contact Length":"0.445\\\" (11.30mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.225\\\" (5.72mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8650","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2a3c4564b83d1e0e77f2ae6802960dde.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/75844-318-34LF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 75844-318-34LF?","answer":"Contact the storefront with your BOM quantity for a same-day quote."},{"question":"What is the pitch of 75844-318-34LF?","answer":"The pitch is 0.100\" (2.54 mm) on both the row spacing and the pin-to-pin spacing."},{"question":"Is 75844-318-34LF shrouded or unshrouded?","answer":"It is an unshrouded header — there is no plastic shroud around the pins, so the mating receptacle relies on board-level alignment rather than a keying feature."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/75844-318-34LF","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/75844-318-34LF when reusing this data.
