It's a board-to-wire interconnect — the header solders to the PCB and mates with a crimp-style receptacle housing (the matching half carries the wires). The 3.00 mm pitch gives enough room between contacts for the 600 V rating without blowing up the board footprint, and the 8 A per-circuit rating puts it in the power-interconnect class, not signal. Typical applications include automotive, industrial, medical, and telecom harness assemblies where vibration resistance and a positive lock matter. ## Key Features That Drive the Fit The 15.0 µin gold plating on the mating contacts handles repeated mating cycles without the fretting corrosion you'd get from tin-on-tin in a high-vibration environment. The solder tails get a thick 100.0 µin tin finish — standard for reflow, no surprises. The 4-wall shrouding protects the pins during handling and guides the receptacle into alignment; the locking ramp on the shroud gives an audible click when fully mated, which matters when the connector is buried in a harness bundle. Board lock features on the SMT feet hold the header in place during reflow and resist the shear force from the cable strain on the mated assembly. ## Mounting and Termination Reality This is a surface-mount header — it reflows onto the PCB, no through-hole. The 0.118\" (3.00 mm) row spacing matches the pitch, so the footprint is a straightforward dual-row pad array. The LCP (Liquid Crystal Polymer) housing with glass fill handles the reflow profile without warping and carries a UL94 V-0 flammability rating, which is the standard for equipment inside an enclosure. The operating temperature range of -40°C to 105°C covers automotive underhood and industrial cabinet environments.","metaTitle":"Molex Micro-Fit 3.0 430450616, 6-Pos SMT Header, 3mm Pitch","metaDescription":"Molex 430450616 Micro-Fit 3.0 SMT header, 6 circuits dual-row, 0.118\" (3.00mm) pitch, 8A per circuit, 600V, gold mating contacts, board lock, active","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":"430450616","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 6POS 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":"6","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":"$3.8","priceTiers":[{"qty":1,"price":"$3.80000","currency":"USD"},{"qty":10,"price":"$3.34500","currency":"USD"},{"qty":100,"price":"$2.66080","currency":"USD"},{"qty":200,"price":"$2.66080","currency":"USD"},{"qty":1000,"price":"$2.20466","currency":"USD"},{"qty":2000,"price":"$2.12864","currency":"USD"},{"qty":5000,"price":"$1.97659","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430450616/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for Molex 430450616?","answer":"The 430450616 is a male pin header that mates with a Micro-Fit 3.0 receptacle housing (the female, crimp-terminal side). The receptacle housing carries the matching crimp terminals and wires; the header solders to the PCB. The locking ramp on the header shroud engages the receptacle latch for a vibration-resistant connection."},{"question":"Is Molex 430450616 RoHS compliant?","answer":"Yes, the 430450616 is ROHS3 compliant per the listing."},{"question":"What is the current rating of Molex 430450616?","answer":"The header is rated 8 A per circuit at 600 V. That 8 A per contact is the headline figure — it's a power-class rating for a 3.00 mm pitch SMT connector, so the limiting factor in practice is the PCB trace width and the ambient temperature inside the enclosure."},{"question":"What is the board lock feature on Molex 430450616?","answer":"The board lock is a pair of metal retention features on the SMT feet that hold the header in place during reflow soldering and resist shear forces from the cable strain on the mated assembly.
