The shrouded 4-wall housing with locking ramp provides polarization and positive retention during mating. Tin-plated brass contacts are rated for through-hole solder termination. ## Selection notes for the Mini-Fit Jr 5566 series The 0.165\" (4.20 mm) pitch and dual-row layout define the board footprint across the series. The 6-circuit 0039293066 is the smallest position count in the 5566 header family; larger siblings (e.g. 8-, 10-, 12-circuit) share the same pitch, row spacing, and contact plating, so the footprint scales with position count. The locking ramp and 4-wall shrouding reduce the risk of mis-mating in high-vibration environments. The UL94 V-2 polyamide housing meets the flammability rating required for most industrial and telecom enclosures.","metaTitle":"0039293066 Molex Mini-Fit Jr 5566 Header, 6-Pos 4.20mm","metaDescription":"Molex Mini-Fit Jr 5566 header 0039293066: 6 positions, dual row, 0.165\" (4.20 mm) pitch, tin-plated contacts, through-hole solder, shrouded 4-wall with locking","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Mini-Fit Jr 5566","Features":"-","Packaging":"Bulk","Shrouding":"Shrouded - 4 Wall","Part Status":"Active","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)","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":"6","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":"35.0µin (0.90µm)","Contact Finish Thickness - Mating":"35.4µin (0.90µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the listed style of 0039293066?","answer":"The connector style is Board to Cable/Wire, a male pin header that mates with a Mini-Fit Jr receptacle housing."},{"question":"What compliance documentation is available for 0039293066?","answer":"The housing carries a UL94 V-2 flammability rating.
