The board lock feature adds extra shear-force retention during solder reflow and against cable strain after assembly. It is ROHS3 compliant.","metaTitle":"Molex 0039289168 Mini-Fit Jr 5566 Header – 16 Pos","metaDescription":"Molex 0039289168: 16-position dual-row header, 4.20mm pitch, 30µin gold mating contacts, locking ramp, through-hole solder, 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":"003928","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"16","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":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5500","priceTiers":[{"qty":1,"price":"$9.55000","currency":"USD"},{"qty":10,"price":"$8.30200","currency":"USD"},{"qty":80,"price":"$6.84938","currency":"USD"},{"qty":945,"price":"$5.68701","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0039289168/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 0039289168 in the Mini-Fit Jr 5566 family?","answer":"The Mini-Fit Jr 5566 series includes headers with different circuit counts and plating options.
