The 53660-4: ROHS3 compliant.
Wire Gauge, Finish, and Foil Crimp Area
Rated for 8 AWG wire — this is a heavy-gauge terminal suited for power distribution or busbar-level connections where the foil tab carries high current. Tin contact finish on a brass body keeps the interface corrosion-resistant for indoor equipment environments. The barrel, tap terminal style accepts a foil crimp area of 0.623" x 0.625" (15.82mm x 15.88mm). That rectangular pocket is sized for a flat foil conductor — the crimp tool must match the die set to this specific width and length to achieve the rated pull-out force.
Termi-Foil Series Positioning
Part of the Termi-Foil series, which focuses on heavy-gauge foil termination for power and ground applications. Unlike standard ring or spade terminals, the barrel tap design captures a flat foil tab rather than a round wire — common in transformer windings, battery interconnects, and high-current bus bars.
Cross-Reference and Equivalent Parts
No official cross-reference or pin-compatible alternative is listed by the manufacturer for this Termi-Foil barrel tap terminal. The base product number 53660 covers the series; the -4 suffix specifies the 8 AWG, tin finish variant. A form-fit-function substitute would need to match the 0.623" x 0.625" foil crimp area and 8 AWG wire entry — verify die compatibility before substituting.
Crimp Tooling and Termination
Termination requires a crimp tool with a die set sized for the 0.623" x 0.625" foil crimp area and 8 AWG barrel. TE Connectivity offers application tooling for the Termi-Foil series — consult the tooling catalog for the specific die part number. The overall length of 1.197" (30.40mm) sets the clearance needed in the crimp nest.
