The 2.00mm pitch matches the footprint of the mating CT header — the board-side pad spacing is fixed by that dimension. IDC termination on discrete wire means each conductor is individually pressed into an insulation-displacement slot, not mass-terminated from a ribbon cable. The 26-28 AWG range is narrow: 24 AWG is too thick to seat, 30 AWG won't be gripped by the slot. Tin contacts are rated for a modest number of mating cycles — fine for a one-time assembly or occasional field service, not for repeated disconnect under a panel.","metaTitle":"TE 6-173977-4 CT Receptacle, 4 Pos, 2.00mm Pitch, IDC","metaDescription":"TE 6-173977-4 CT series 4-position receptacle, 2.00mm pitch, IDC termination for 26-28 AWG discrete wire, tin contacts.
