Tin-plated mating contacts, a 4-wall shrouded housing with a locking ramp, and an integral board lock provide retention during reflow and against cable strain. ## Shrouded housing and locking ramp The 4-wall shroud protects the male pins from damage during handling and mating, while the locking ramp on the housing provides audible and tactile feedback when fully seated with the matching Mini-Fit Jr receptacle. The board lock holds the header in place during wave soldering and adds mechanical retention against vibration and cable pull forces.","metaTitle":"Molex 0039299147 Mini-Fit Jr Header, 14 Pos, 4.20mm","metaDescription":"Molex Mini-Fit Jr 5566 header 0039299147: 14 positions, dual row, 4.20 mm pitch, tin-plated contacts, through-hole, shrouded with locking ramp and board lock.","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","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":"14","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":"$2.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8cc0c748195706a1092a329e7d709472.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0039299147/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/0039299147","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/molex/0039299147 when reusing this data.
