Through-hole solder termination gives a robust mechanical anchor — the 0.140\" (3.56mm) contact tail length is standard for a 1.6 mm thick PCB. ## Current, Voltage, and Temperature Ceilings Rated 8 A per contact at 300 V under UL conditions. The 8 A figure is the per-contact current at a defined temperature rise — in practice, derate if the ambient inside the enclosure exceeds 105°C (the housing material limit). ## Mating and Cross-Reference Notes The base product number 039502 covers the series — the suffix identifies position count and orientation. No official pin-compatible alternative from Molex is listed; the closest functional match within the series would be a different position count or orientation variant.","metaTitle":"Molex 0395021020 Eurostyle ESE 39502 Header – 20 Pos, 3.50mm","metaDescription":"Molex 0395021020 Eurostyle ESE 39502 terminal block header, 20 positions, 3.50mm pitch, right-angle, through-hole, tin contacts.","metaKeywords":null},"attributes":{"series":"Eurostyle ESE 39502","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Header Plugs & Sockets"],"specifications":{"Mfr":"Molex","Type":"Header, Male Pins, Shrouded (4 Side)","Color":"Black","Pitch":"0.138\\\" (3.50mm)","Series":"Eurostyle ESE 39502","Package":"Bulk","Features":"-","Screw Size":"-","Current - UL":"8 A","Voltage - UL":"300 V","Current - IEC":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","Plug Wire Entry":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Insulation Height":"0.270\\\" (6.86mm)","Termination Style":"Solder","Wire Strip Length":"-","Header Orientation":"90°, Right Angle","Ingress Protection":"-","Base Product Number":"039502","Contact Tail Length":"0.140\\\" (3.56mm)","Number of Positions":"20","Positions Per Level":"20","Contact Mating Finish":"Tin","Operating Temperature":"-40°C ~ 105°C","Wire Gauge or Range - AWG":"-","Wire Gauge or Range - mm²":"-","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.3000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.30000","currency":"USD"},{"qty":10,"price":"$6.38400","currency":"USD"},{"qty":100,"price":"$5.16820","currency":"USD"},{"qty":1000,"price":"$4.25614","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15841be7a15fddbfba044e98cdee2083.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy Molex 0395021020?","answer":"Molex 0395021020 is available through independent distribution."},{"question":"What is the mating connector for 0395021020?","answer":"It mates with a Eurostyle ESE 39502 plug (female socket) of the same 20-position, 3.50mm pitch configuration.
