Through-hole solder tails give it a solid mechanical anchor through wave solder, and the integrated board lock holds the body down during the process so the jack doesn't float off the pads. ## Cat3 Rating — What It Means for Cable Compatibility This jack carries a Cat3 performance rating, which caps its usable frequency at 16 MHz. That's fine for POTS voice lines and 10BASE-T Ethernet, but it is not rated for Cat5e (100 MHz) or Cat6 (250 MHz) applications. The 6p4c contact arrangement also means only the centre four positions are wired; the outer two positions are unpopulated, so a standard 6p6c plug will mate but only the centre four contacts will connect. ## Gold Contacts and Board Lock — Fit for a Panel-Mount Life The housing is polybutylene terephthalate (PBT), a common jack material that holds up to wave-solder temperatures and resists flux residue. For a wall-plate or desk phone, that's the right level of retention.","metaTitle":"TE 1-1705950-2 Modular Jack, 6p4c R/A Cat3","metaDescription":"TE Connectivity 1-1705950-2 modular jack, 6p4c (RJ11/RJ14), right-angle, through-hole, unshielded, Cat3 rated, gold contacts, board lock.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Modular / RJ Connectors","Modular Jacks (RJ)"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Tray","Ratings":"Cat3","Features":"Board Lock","LED Color":"Does Not Contain LED","Shielding":"Unshielded","Orientation":"90° Angle (Right)","Termination":"Solder","Mounting Type":"Through Hole","Tab Direction":"Down","Connector Type":"Jack","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Active","Number of Ports":"1","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polybutylene Terephthalate (PBT)","Ingress Protection":"-","Base Product Number":"1705950","Operating Temperature":"-","Contact Finish Thickness":"6.00µin (0.152µm)","Number of Positions/Contacts":"6p4c (RJ11, RJ14)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0500","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.05000","currency":"USD"},{"qty":10,"price":"$0.98100","currency":"USD"},{"qty":25,"price":"$0.94480","currency":"USD"},{"qty":80,"price":"$0.93575","currency":"USD"},{"qty":230,"price":"$0.84439","currency":"USD"},{"qty":440,"price":"$0.81702","currency":"USD"},{"qty":1440,"price":"$0.66640","currency":"USD"},{"qty":2880,"price":"$0.62076","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d6f2da0b47a5b8e034c1a8b427833739.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy TE 1-1705950-2 and what is the lead time?","answer":"Availability and current lead time are confirmed at quote time — submit an RFQ for your quantity and we'll source it from the channel."},{"question":"Is 1-1705950-2 compatible with Cat5e or Cat6 cables?","answer":"No. The 1-1705950-2 is rated Cat3, which limits it to 16 MHz operation.
