The board guide feature further aids alignment during assembly, reducing the risk of stubbing pins when the harness is mated blind. ## Voltage and temperature — insulation class Rated 250 VAC/DC, the header suits signal and low-power distribution within equipment enclosures.","metaTitle":"Molex 5016452021 iGrid 2.00 mm Header, 20-Pin, Shrouded","metaDescription":"Molex 5016452021 iGrid 501645 series, 2.00 mm pitch, 20-position dual-row shrouded header, latch holder, 250 VAC/DC, UL94 V-0.","metaKeywords":null},"attributes":{"series":"iGrid 501645","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":"iGrid 501645","Package":"Bag","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.079\\\" (2.00mm)","Product Status":"Active","Voltage Rating":"250VAC/DC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.472\\\" (12.00mm)","Ingress Protection":"-","Base Product Number":"501645","Insulation Material":"Polyamide (PA), Nylon, Glass Filled","Number of Positions":"20","Row Spacing - Mating":"0.079\\\" (2.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.126\\\" (3.20mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"39.4µin (1.00µm)","Contact Finish Thickness - Mating":"39.4µin (1.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3500","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$1.11700","currency":"USD"},{"qty":100,"price":"$0.93080","currency":"USD"},{"qty":1000,"price":"$0.74465","currency":"USD"},{"qty":2500,"price":"$0.67484","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e6635bb5d0f563e5a2f6ba7d429113d7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of Molex 5016452021?","answer":"2.00 mm (0.079 inches) on both the mating pitch and the row spacing."},{"question":"What is the mating part for 5016452021?","answer":"The mating half is a Molex iGrid 501645 series receptacle housing (e.g., 501645-xxxx) with crimp terminals.
