It uses a 0.118\" (3.00mm) pitch on both rows, with a shrouded 4-wall housing and a locking ramp for secure mating in vibration-prone environments like automotive and industrial equipment. The gold-plated mating contacts (30.0 µin) handle repeated mating cycles without fretting corrosion, while the tin-plated posts (100.0 µin) provide a reliable solder joint through the through-hole termination. The housing is molded from glass-filled LCP rated UL94 V-0, and the operating temperature range spans -40°C to 105°C, making it suitable for under-hood automotive, industrial cabinet, and telecom equipment where flame retardance and thermal cycling are requirements. The 0.125\" (3.18mm) solder tail length is standard for through-hole PCB mounting.","metaTitle":"Molex Micro-Fit 3.0 430452029 Header, 20 Pos, 3mm Pitch, 8A","metaDescription":"Molex 430452029 Micro-Fit 3.0 header, 20-position dual-row, 3.00mm pitch, through-hole vertical, gold-plated contacts, 8A/600V, shrouded with locking ramp.","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":"430452029","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 20POS 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":"20","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":"$8.38","priceTiers":[{"qty":1,"price":"$8.38000","currency":"USD"},{"qty":10,"price":"$7.33300","currency":"USD"},{"qty":80,"price":"$5.93650","currency":"USD"},{"qty":1296,"price":"$4.88890","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430452029/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and position count of 430452029?","answer":"The 430452029 has 20 positions arranged in two rows on a 0.118\" (3.00mm) pitch, with the same 0.118\" (3.00mm) row spacing."},{"question":"Is 430452029 RoHS compliant and what is the operating temperature?","answer":"Yes, the 430452029 is ROHS3 compliant.
