It is a board-to-wire interconnect — a shrouded through-hole header that mates with the matching Micro-Fit 3.0 receptacle housing and crimp terminals. The 8 A per-circuit rating at 600 V is the headline power spec, but the real duty limit comes from the tin-plated mating surface. The through-hole kinked-pin termination locks the header into the PCB during wave solder — the kink holds the part in place before the solder joint forms, which saves a secondary retention operation. The dual-row layout with 0.118\" (3.00 mm) row spacing keeps the board footprint compact while leaving enough creepage for the 600 V rating.","metaTitle":"Molex Micro-Fit 3.0 430451412, 14-Pin Header, 3mm Pitch","metaDescription":"Molex 430451412 Micro-Fit 3.0 14-position dual-row header, 3.00mm pitch, 8A per circuit, 600V, tin-plated contacts, shrouded 4-wall with locking ramp.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Style":"Board to Cable/Wire","title":"430451412","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 14POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.118\\\" (3.00mm)","Voltage Rating":"600V","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.390\\\" (9.91mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"14","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.13","priceTiers":[{"qty":1,"price":"$3.13000","currency":"USD"},{"qty":10,"price":"$2.75200","currency":"USD"},{"qty":80,"price":"$2.18938","currency":"USD"},{"qty":1872,"price":"$1.75152","currency":"USD"},{"qty":5616,"price":"$1.62641","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/87d7da4977842b6aed6d2b05fd6ad753.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451412/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and pin count of Molex 430451412?","answer":"The 430451412 is a 14-position header on a 3.00 mm pitch, dual-row layout."},{"question":"What is the current rating of 430451412?","answer":"Rated 8 A per circuit at 600 V, with tin-plated contacts at 100.0 µin (2.54 µm) on the mating surface."},{"question":"Is 430451412 a shrouded header with locking ramp?","answer":"Yes, it is a shrouded 4-wall header with an integral locking ramp and a board guide for alignment during assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451412","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/molex/430451412 when reusing this data.
