The through-hole solder tails with board lock anchor the header during wave solder and resist shear from the mated cable assembly. ## Board Lock and Through-Hole Termination The board lock feature is a pair of plastic pegs that snap into the PCB during placement, holding the header in position before soldering. This prevents skew during wave solder and adds mechanical retention against cable strain after the mating connector is latched. The brass square pins are rated for the full Mini-Fit Jr current range; derate above 85 °C ambient per the series derating curve.","metaTitle":"Molex 0039299207 Mini-Fit Jr Header 20POS 4.2mm Vertical","metaDescription":"Molex 0039299207 Mini-Fit Jr 5566 series vertical header, 20 circuits, 4.20mm pitch, dual-row, through-hole, locking ramp, board lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Mini-Fit Jr 5566","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":"Mini-Fit Jr 5566","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose, Industrial, 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":"0.165\\\" (4.20mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.504\\\" (12.80mm)","Ingress Protection":"-","Base Product Number":"003929","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"20","Row Spacing - Mating":"0.165\\\" (4.20mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.138\\\" (3.50mm)","Current Rating (Amps)":"-","Operating Temperature":"-","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":"35.0µin (0.90µm)","Contact Finish Thickness - Mating":"35.4µin (0.90µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3900","priceTiers":[{"qty":1,"price":"$4.39000","currency":"USD"},{"qty":10,"price":"$3.86600","currency":"USD"},{"qty":80,"price":"$3.07550","currency":"USD"},{"qty":945,"price":"$2.54823","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dda46d3eb024d416c6a4bbca1a08663c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0039299207/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for Molex 0039299207?","answer":"This vertical header mates with a Mini-Fit Jr 5566 series receptacle housing (e.g., Molex 39-01-2205 or equivalent 20-position dual-row) loaded with female crimp terminals."},{"question":"Is 0039299207 RoHS compliant?","answer":"Yes, 0039299207 is ROHS3 compliant per the manufacturer's declaration."},{"question":"Is 0039299207 available in tape and reel packaging?","answer":"No, this part is packaged in a tray.
