The 0.165\" row spacing mirrors the pitch, keeping the two rows aligned for a clean press-fit into the housing. In a panel where the harness is routed tight to the board edge, that board lock keeps the header from lifting off the pads when the cable gets snagged. If the connector sees quarterly disconnect in a field-service application, the tin surface will wear to copper after roughly 25–50 cycles, depending on insertion force. For a one-time mate-and-forget assembly, tin is the cost-effective choice. The 100.0µinch thickness on the post means the solder joint wets reliably through the tin layer during wave soldering — no extra flux step needed for a clean fillet. ## Mating with the Receptacle 39-01-2105 This header mates directly with the Mini-Fit Jr receptacle housing 39-01-2105 (10 circuits, 2 rows). The 4-wall shroud on the header aligns the pins before the contacts touch, so the terminals don't bend on insertion.","metaTitle":"Molex 0039306107 Mini-Fit Jr Header, 10 Pos, 4.2mm, Tin","metaDescription":"Molex 0039306107 Mini-Fit Jr 5566 series header, 10 circuits, 4.20mm pitch, tin-plated contacts, board lock, shrouded 4-wall, active production.","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":"003930","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"10","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-2","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7200","priceTiers":[{"qty":1,"price":"$1.72000","currency":"USD"},{"qty":10,"price":"$1.46300","currency":"USD"},{"qty":80,"price":"$1.20900","currency":"USD"},{"qty":945,"price":"$0.95446","currency":"USD"},{"qty":4900,"price":"$0.84628","currency":"USD"},{"qty":10000,"price":"$0.82719","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4459191f5346222fed137ad5f932e40e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0039306107/alternatives.json"},"ai":{"faq":[{"question":"What is the pinout of Molex 0039306107?","answer":"This is a 10-position, 2-row header with all positions loaded.
