For BOM positions already in production, the only sourcing path is through independent surplus channels — quantities are lot-specific and confirmed at RFQ. If you are designing a new board, a pin-compatible alternative in the same pitch and circuit count will require a review of the mating half and board footprint. Through-hole solder termination with a contact post length of 0.114\" (2.90 mm) — this sets the board thickness and solder fillet geometry. The header is loaded with all 14 positions, so no blank positions to account for in the harness design.","metaTitle":"1-1971818-4 TE Connectivity Header, 14 Pos, 2.50 mm","metaDescription":"1-1971818-4 TE Connectivity AMP Connectors header, 14 circuits, 2.50 mm pitch, through-hole, tin-plated, shrouded, glow wire compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"-","Package":"Bulk","Features":"Board Guide, Glow Wire Compliant","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Tab","Contact Shape":"Rectangular","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.098\\\" (2.50mm)","Product Status":"Obsolete","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.610\\\" (15.49mm)","Ingress Protection":"-","Base Product Number":"1971818","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"14","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.114\\\" (2.90mm)","Current Rating (Amps)":"-","Operating Temperature":"-40°C ~ 120°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-1971818-4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1-1971818-4","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/te-connectivity-amp-connectors/1-1971818-4 when reusing this data.
