With a 3.00mm pitch, it mates with the corresponding Micro-Fit 3.0 receptacle housing (sold separately) using a locking ramp for positive retention. Rated 8A per circuit at 600V, this header carries enough headroom for low-to-mid power distribution inside an enclosure — think a PSU output or a motor drive interconnect. For a right-angle header, that matters — the lever arm of the mated cable puts more peel stress on the solder joints than a vertical header would.","metaTitle":"Molex Micro-Fit 3.0 430451021, 10-Pin Right-Angle Header, 8A","metaDescription":"Molex 430451021 Micro-Fit 3.0 right-angle header, 10 circuits, dual-row, 3.00mm pitch, rated 8A at 600V, tin-plated contacts, board lock, UL94 V-0.","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":"430451021","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER R/A 10POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, 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":"10","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":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.29","priceTiers":[{"qty":1,"price":"$3.29000","currency":"USD"},{"qty":10,"price":"$2.89600","currency":"USD"},{"qty":80,"price":"$2.30338","currency":"USD"},{"qty":1224,"price":"$1.90854","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dfff01b2e2ed78f9b97db4b2de03830c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451021/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for molex 430451021?","answer":"The 430451021 mates with a Micro-Fit 3.0 receptacle housing (the matching 10-circuit, dual-row, 3.00mm pitch female half).
