The 3.00 mm pitch and 8 A per circuit rating place it in the power interconnect class, not signal-level, so the wire gauge and trace width on the PCB need to be sized accordingly. ## Key Features for the Build and the Board Gold plating on the mating contacts (30.0 µin) supports repeated mating cycles in corrosive or humid environments, while the tin-plated solder tails (100.0 µin) are standard for reliable through-hole soldering. The UL94 V-0 LCP insulator handles the -40°C to 105°C operating range without issue.","metaTitle":"Molex Micro-Fit 3.0 430451623","metaDescription":"Molex Micro-Fit 3.0 430451623, 16-position dual-row right-angle header, 3.00mm pitch, 8A per circuit, 600V, gold mating contacts, board lock.","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":"430451623","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER R/A 16POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, 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":"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":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.31","priceTiers":[{"qty":1,"price":"$7.31000","currency":"USD"},{"qty":10,"price":"$6.39400","currency":"USD"},{"qty":80,"price":"$5.17625","currency":"USD"},{"qty":1584,"price":"$4.17144","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451623/alternatives.json"},"ai":{"faq":[{"question":"Is 430451623 compatible with Micro-Fit 3.0 receptacles?","answer":"Yes, the 430451623 is a Micro-Fit 3.0 header and mates with the standard Micro-Fit 3.0 receptacle housings (e.g., 43025 series) and their matching crimp terminals.
