It covers RJ11, RJ12, RJ14, and RJ25 wiring schemes — the same 6p6c footprint that handles single and dual telephone lines or low-speed data links. The translucent clear polycarbonate housing lets you see the wire seating through the wall, which saves a continuity check when you're punching down a run. Rated Cat3, this plug suits voice and low-speed data in structured cabling where the cable plant is solid 26-28 AWG flat oval. Wire gauge is 26-28 AWG solid — that's the standard range for Cat3 station cable. The housing is polycarbonate (PC), translucent clear. PC holds up to the impact of a dropped handset or a boot stepping on a loose patch cable, and the clear body means you can verify the wire is fully seated before you snap the plug into the jack. Unshielded, so it's for unshielded twisted-pair (UTP) cable runs only. ## Lifecycle — Obsolete, Sourced to Order For BOM lines that still call out this exact plug, we source it through independent distribution channels against an RFQ. If you need a drop-in alternative, the closest parametric match is another 6p6c IDC plug from the same 557970 series with the same wire gauge and plating; confirm the housing colour and keying against your assembly drawing before substituting.","metaTitle":"TE Connectivity 5-557970-3 RJ11 Plug, 6p6c, IDC, Obsolete","metaDescription":"TE Connectivity 5-557970-3 RJ11/RJ12 plug, 6p6c, IDC termination for 26-28 AWG flat oval solid wire.
