It is a board-to-wire interconnect — a shrouded, right-angle SMT header with tin-plated square pins on a 3.00 mm pitch. The 4-wall shroud and locking ramp give it positive mating retention, and the integrated board locks hold it in place during reflow and resist shear from the cable assembly. Rated 8 A per circuit at 600 V, it is specified for automotive, industrial, medical, and telecom applications where a vibration-resistant, mid-current power connection is needed. ## What the Key Ratings Mean for Fit The 3.00 mm pitch is the standard Micro-Fit 3.0 spacing — it sets the PCB footprint and guarantees mating compatibility with the matching receptacle housing. The 8 A per circuit rating is the headline power spec; at this pitch and with tin-plated contacts, it supports moderate-current power distribution in harness assemblies, not just signal duty. The right-angle SMT orientation places the connector parallel to the board, which suits board-edge or space-constrained enclosures. The locking ramp provides a tactile lock when mated, and the board locks anchor the header to the PCB, so the assembly resists vibration and cable strain without relying solely on solder joints. ## Sourcing and Lifecycle The 430451806 carries an Active lifecycle status and is ROHS3 compliant. No official successor or cross-reference is on record — the part is the current production member for its position count in the Micro-Fit 3.0 family.","metaTitle":"Molex Micro-Fit 3.0 430451806 Header, 18 Pos, 3mm, 8A","metaDescription":"Molex 430451806 Micro-Fit 3.0 SMT right-angle header, 18 circuits dual-row, 3.00mm pitch, tin contacts, 8A, 600V, shrouded with board locks.","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":"430451806","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 18POS 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":"18","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","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":"$6.9","priceTiers":[{"qty":1,"price":"$6.90000","currency":"USD"},{"qty":10,"price":"$6.04000","currency":"USD"},{"qty":100,"price":"$4.88930","currency":"USD"},{"qty":200,"price":"$4.88935","currency":"USD"},{"qty":1000,"price":"$4.02651","currency":"USD"},{"qty":2000,"price":"$3.94023","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/955975b21a3e7e0c1f6da7f32573f210.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451806/alternatives.json"},"ai":{"faq":[{"question":"Is the 430451806 RoHS compliant?","answer":"Yes, the 430451806 is ROHS3 compliant."},{"question":"What is the pitch of the Molex 430451806?","answer":"The mating pitch is 0.118\" (3.00 mm), which is the standard Micro-Fit 3.0 spacing.
