Rated for automotive, general purpose, industrial, medical, and telecommunications applications — the locking ramp and 4-wall shrouding keep the mated pair secure under vibration. ## Current Rating and Contact Design Male pins are square brass alloy with gold on the mating face and 100.0µin tin on the solder tails — the tin finish wets well during wave soldering, while the gold interface maintains low contact resistance over repeated mate cycles. ROHS3 compliant — the part meets the latest EU restriction-of-hazardous-substances directive for lead, mercury, cadmium, and other substances. No official pin-compatible alternative or successor is listed by Molex for this specific order code. The functional replacement would be another Micro-Fit 3.0 header with the same circuit count and pitch — verify the BOM position count and mating half before committing.","metaTitle":"0430452001 Molex Micro-Fit 3.0 Header, 20 Pos, Right Angle","metaDescription":"0430452001 Molex Micro-Fit 3.0 43045 series, 20-position dual-row right-angle header, 3.00mm pitch, gold-plated contacts, board lock, RoHS3 compliant.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","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)","Product Status":"Active","Voltage Rating":"600V","lifecycle_stage":"unknown","Contact Material":"Brass Alloy","Insulation Color":"Black","Insulation Height":"0.290\\\" (7.37mm)","Ingress Protection":"-","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"20","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","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":"$7.2600","priceTiers":[{"qty":1,"price":"$7.26000","currency":"USD"},{"qty":10,"price":"$6.35000","currency":"USD"},{"qty":80,"price":"$5.14075","currency":"USD"},{"qty":1296,"price":"$4.23352","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/955975b21a3e7e0c1f6da7f32573f210.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430452001/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for Molex 0430452001?","answer":"The mating half is a Micro-Fit 3.0 receptacle housing (e.g., Molex 043025 series) with crimp terminals.
