The translucent-blue polycarbonate housing allows a quick visual check that the conductors are fully seated through the IDC slots, a practical aid during field termination or harness assembly. ## Termination and Cable Compatibility Termination is IDC — insulation displacement — so no stripping or soldering is needed. The plug accepts 26-28 AWG solid wires in a flat oval cable profile. ## Sourcing Reality for an Obsolete Part This part is marked Obsolete.","metaTitle":"TE 5-557972-3 RJ45 Plug, IDC, Cat5, 8p8c, Obsolete","metaDescription":"TE Connectivity 5-557972-3 RJ45 plug, IDC termination for 26-28 AWG solid flat oval cable.
