Product details

PIDG Strato-Therm ring terminal for 12-14 AWG

The 1577639-1: The nickel-plated copper contact is 0.032" (0.81mm) thick, insulated with PEEK, and the serrated termination bites into the conductor for a gas-tight joint.

Stud size options in the same wire gauge

Within the 12-14 AWG PIDG Strato-Therm family, the 1577639-1 (#8 stud) sits alongside the 1577640-1 (#10 stud) — both share the same 0.343" (8.71mm) outer width, 0.905" (22.99mm) overall length, and PEEK insulation. The stud size is the selection axis: the #8 stud fits M4 or #8 screw terminals, while the #10 stud fits M5 or #10 hardware.

Frequently asked questions

Will the 1577639-1 fit a panel designed for the 1577640-1?

The 1577639-1 uses a #8 stud; the 1577640-1 uses a #10 stud. The outer width (0.343" or 8.71mm) and overall length (0.905" or 22.99mm) are identical, but the stud hole diameter differs — the #8 stud terminal will not fit a #10 screw without a bushing.

What compliance documentation does TE Connectivity provide for this terminal?

The 1577639-1 is RoHS Compliant. Additional compliance documentation (REACH, UL, IEC) is available from TE Connectivity upon request.
