Product details

Insulated spade for 14-16 AWG circuits

The 52421-3 is the #8-stud member of TE's PIDG spade terminal family, accepting 14-16 AWG wire with a serrated crimp and tin-plated phosphor bronze contact. The blue nylon insulation covers a 0.115" to 0.170" insulation diameter range and the overall length is 0.979" (24.87 mm).

Stud-size selection within PIDG

Within the PIDG 14-16 AWG blue insulated spade line, the 52421-3 uses an 8-stud tongue (0.164" inside opening) while the 52420-3 uses a 6-stud tongue (0.140" opening) — the crimp length, wire range, and insulation are otherwise shared. The 52936-3 shares the 8-stud size but uses a wider outer-edge profile (0.375" vs 0.281") and a slightly different insulation diameter cap (0.182" vs 0.170").

Frequently asked questions

What is the closest functional second-source to 52421-3?

The 52420-3 is the same PIDG series, same wire range and insulation, but uses a #6 stud (0.140" tongue opening) instead of #8 — the crimp tooling and wire preparation are identical.

Will 52421-3 drop into a panel specified around 52420-3 without rewiring?

No — the stud size differs (#8 vs #6). The 52421-3 requires a #8 stud or screw; the 52420-3 fits a #6 stud. The wire range and insulation diameter are the same.
