Product details

22 AWG ring lug for a #6 stud

The 51863-2 is a PIDG-series ring terminal from TE Connectivity, sized for 22 AWG wire and a #6 stud — a common fit for barrier-strip and terminal-block connections where a ring lug under the screw is the standard. Tin-plated copper contact, 0.031" (0.79mm) thick, with an insulated polyamide barrel that accepts wire insulation from 0.038" to 0.110" (0.97mm to 2.79mm).

Same gauge, different stud size

Within the PIDG family, the 51863-2 (#6 stud) sits alongside the 2-36153-3 (#10 stud) — both use 22 AWG, share the same 0.031" (0.79mm) thickness and tin plating, but the #10 version has a wider outer edge (0.312" vs 0.250") and a longer overall length (0.909" vs 0.844").

Frequently asked questions

Will the 51863-2 drop into a panel that was specified around the 51864-9 without rewiring?

No — the 51864-9 is a #10 stud terminal for 14 AWG wire, while the 51863-2 is a #6 stud for 22 AWG. The stud size and wire gauge differ, so a direct swap is not possible without changing the mating stud or wire.
