It carries a 0.118\" (3.00 mm) pitch on both the mating interface and the row spacing, with a 4-wall shrouded housing and a locking ramp for secure mating. Rated 8 A per circuit at 600 V, with tin-plated brass contacts (60.0 µin on the mating surface), it operates from -40°C to 105°C and carries a UL94 V-0 flammability rating. Typical applications include automotive harnesses, industrial control cabinets, medical equipment, and telecom infrastructure. This through-hole header mates with Micro-Fit 3.0 receptacle housings loaded with matching crimp terminals. Against the 12-circuit 430451212, the 430451027 shares the same 3.00 mm pitch, dual-row layout, 8 A rating, and tin plating. The only decision-relevant difference is the position count: 10 circuits vs 12 circuits.","metaTitle":"Molex Micro-Fit 3.0 430451027, 10-Pin Header, 8 A, 600 V","metaDescription":"Molex 430451027 Micro-Fit 3.0 header, 10 circuits, 3.00 mm pitch, dual-row, through-hole, tin-plated contacts rated 8 A at 600 V.","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":"430451027","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 10POS 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":"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":"$2.56","priceTiers":[{"qty":1,"price":"$2.56000","currency":"USD"},{"qty":10,"price":"$2.24900","currency":"USD"},{"qty":80,"price":"$1.78925","currency":"USD"},{"qty":1224,"price":"$1.48252","currency":"USD"},{"qty":6120,"price":"$1.32915","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451027/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating and voltage rating of Molex 430451027?","answer":"The 430451027 is rated 8 A per circuit at 600 V.
