Gold-plated mating contacts (15.0 µin) handle repeated mating cycles in harness service without fretting corrosion. The 3.00 mm pitch and 0.118\" row spacing set the board footprint — two rows of 8 positions each, requiring a 16-pad SMT layout with a 3.00 mm staggered grid. Termination is SMT — the header is placed on the PCB and reflow-soldered; the solder retention features hold it in position during the process.","metaTitle":"Molex Micro-Fit 3.0 430451619, 16-Pos SMT Header, 3.00mm, 8A","metaDescription":"Molex 430451619 Micro-Fit 3.0 SMT header, 16 circuits, dual-row, 3.00mm pitch, gold-plated contacts, 8A, 600V, locking ramp, active production, sourced to","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":"430451619","Series":"Micro-Fit 3.0 43045","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER SMD 16POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","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","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":"$6.89","priceTiers":[{"qty":1,"price":"$6.89000","currency":"USD"},{"qty":10,"price":"$6.02800","currency":"USD"},{"qty":100,"price":"$4.87990","currency":"USD"},{"qty":200,"price":"$4.87990","currency":"USD"},{"qty":1000,"price":"$4.01873","currency":"USD"},{"qty":2000,"price":"$3.93262","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/00ca37772e7543c28ce45f816c4f34a6.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451619/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for Molex 430451619?","answer":"The 430451619 mates with a Micro-Fit 3.0 receptacle housing that accepts crimp terminals for 20-24 AWG wire.
