The 3.00 mm pitch and 0.118\" row spacing give enough creepage for the 600 V rating without forcing an oversized board footprint. The kinked solder tails (0.125\" post length) lock into the plated-through holes during wave solder and resist pull-out from cable strain. No secondary latch or screw lock, so the vibration resistance depends on the ramp engagement and the shroud walls. This header mates with any Micro-Fit 3.0 receptacle housing in the same 16-circuit, dual-row configuration — the matching crimp housings use the 43045 series female terminals (20-24 AWG). The through-hole kinked-pin termination is wave-solder friendly; the kink holds the component in place during board handling before the solder joint sets.","metaTitle":"Molex Micro-Fit 3.0 430451612 Header, 16-Pos, 8A","metaDescription":"Molex 430451612 Micro-Fit 3.0 header, 16-position dual-row, 3.00mm pitch, 8A per circuit at 600V, tin-plated contacts, locking ramp, 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":"430451612","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 16POS 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":"16","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":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.48","priceTiers":[{"qty":1,"price":"$3.48000","currency":"USD"},{"qty":10,"price":"$3.06400","currency":"USD"},{"qty":80,"price":"$2.43700","currency":"USD"},{"qty":1584,"price":"$1.94962","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/456c6c9eb33f9c5466bf6538696e309d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451612/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of Molex 430451612 per circuit?","answer":"The 430451612 is rated 8 A per circuit at 600 V, with tin-plated contacts on both the mating and solder sides."},{"question":"What is the lock type on Molex 430451612 header?","answer":"The 430451612 uses a locking ramp fastening system — the receptacle clicks into the 4-wall shroud for vibration-resistant retention."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451612","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/molex/430451612 when reusing this data.
