It's a right-angle, through-hole solder part with gold-plated phosphor bronze contacts and a PBT housing. The board lock feature holds it down during wave solder and gives the solder joints some shear resistance if the cable gets yanked. The Cat3 rating means this jack is specced for voice and data up to 16 MHz — fine for POTS, ISDN, or 10BASE-T Ethernet, but it won't pass Cat5e or Cat6 certification. ## Last Buy — Plan Your Final Order The 1705950-2 is on Last Buy status. That means TE has stopped regular production and is accepting final orders for a limited window. The exact last-time-buy date is not published in the available documentation, so the window is closing — any stock left after the cut-off moves to surplus channels. No official replacement part number is listed for this jack. If you need a drop-in 6p4c RJ11 jack for a new design, look for a current-production Cat3 or Cat5e jack from TE's standard modular jack portfolio — but verify the footprint and board lock placement against the 1705950-2 drawing before swapping. Through-hole solder tails give a stronger mechanical anchor than an SMT part, especially when paired with the board lock. The 6p4c contact arrangement uses the centre four positions for the signal pair(s); the outer two positions are unused in a standard RJ11 plug but present for mechanical keying. Confirm your cable plug's wiring matches the PCB trace layout before committing the BOM.","metaTitle":"TE 1705950-2 RJ11 Jack, 6p4c, Right-Angle, Cat3, Last Buy","metaDescription":"TE 1705950-2 RJ11 jack, 6p4c, right-angle through-hole, Cat3 rated, gold contacts, board lock.
