It carries an 8 A per contact current rating at a 600 V voltage rating, making it suitable for distributing power in automotive, industrial, medical, and telecommunications equipment. The 3.00 mm pitch provides adequate creepage for the voltage rating without forcing an oversized board footprint. The 30.0 µinch gold plating on the mating contacts supports repeated mating cycles in corrosive or field-service environments, while the tin-plated solder tails (100.0 µinch) ensure reliable wave-solder wetting. The shrouded 4-wall design with a locking ramp provides positive retention and protects pins from damage during handling and mating. Board locks on the through-hole version hold the header in place during wave solder and resist shear forces from cable strain. The UL94 V-0 liquid crystal polymer housing meets the flame rating required for equipment inside enclosures. ## Mating Half and Termination This header mates with the matching Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) that accepts the crimp terminals. The locking ramp on the header engages the latch on the receptacle for a vibration-resistant connection. The through-hole termination with kinked pins provides secure mechanical retention on the PCB before soldering. ## Sourcing and Lifecycle The 430451426 carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"Molex Micro-Fit 3.0 430451426 Header, 14 Pos, 3mm, 8A","metaDescription":"Molex 430451426 Micro-Fit 3.0 header, 14-position dual-row, 3.00 mm pitch, 8 A per contact, 600 V, gold-plated mating contacts, shrouded 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":"430451426","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide, Board Lock","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","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.54","priceTiers":[{"qty":1,"price":"$6.54000","currency":"USD"},{"qty":10,"price":"$5.72700","currency":"USD"},{"qty":80,"price":"$4.63588","currency":"USD"},{"qty":945,"price":"$3.81780","currency":"USD"},{"qty":2400,"price":"$3.62691","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/955975b21a3e7e0c1f6da7f32573f210.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451426/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 430451426?","answer":"The 430451426 mates with the matching Micro-Fit 3.0 receptacle housing (43025 series) that accepts the crimp terminals.
