It's a board-to-cable/wire interconnect — the male pin header solders to the PCB and mates with the corresponding Micro-Fit 3.0 receptacle housing (sold separately) to complete a wire harness. The 3.00 mm pitch and 0.118\" row spacing give enough room for 600 V creepage without forcing an oversized board footprint, and the 8 A per-circuit rating handles moderate power — think an internal DC distribution rail or a multi-wire sensor harness in an automotive or industrial cabinet. ## Key Design Features for the Board and Harness This header mates with the Micro-Fit 3.0 receptacle housing — a 4-circuit, 2-row version like the 430250400 (sold as a housing only; terminals ordered separately). The receptacle accepts 20-24 AWG wire with the matching crimp terminal (Molex 430300001 for 20-24 AWG). For a complete build-to-print BOM, you need the header, the receptacle housing, and the crimp terminals — all three are separate line items.","metaTitle":"Molex Micro-Fit 3.0 430450407, 4-Pin SMT Right-Angle Header","metaDescription":"Molex Micro-Fit 3.0 430450407 4-position SMT right-angle header, 3.00mm pitch, 8A, 600V, gold-plated contacts, board lock.","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":"430450407","Series":"Micro-Fit 3.0 43045","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER SMD R/A 4POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount, Right Angle","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":"0.290\\\" (7.37mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"4","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Current Rating (Amps)":"8A","Operating Temperature":"-40°C ~ 105°C","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.57","priceTiers":[{"qty":1,"price":"$3.57000","currency":"USD"},{"qty":10,"price":"$3.14300","currency":"USD"},{"qty":100,"price":"$2.50010","currency":"USD"},{"qty":200,"price":"$2.50015","currency":"USD"},{"qty":1000,"price":"$2.07154","currency":"USD"},{"qty":2000,"price":"$2.00011","currency":"USD"},{"qty":5000,"price":"$1.85724","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/89423caeaeb58205556b34a0af818760.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430450407/alternatives.json"},"ai":{"faq":[{"question":"Is Molex 430450407 polarized?","answer":"Yes.
