Termi-Foil double face terminal – what it is
The tin-plated copper contact gives a reliable electrical connection at a moderate mating cycle count — suitable for applications where the terminal is crimped once and left in place, like power distribution or battery interconnects inside equipment. The foil crimp area measures 1.125" x 0.505" (28.58mm x 12.83mm), which sets the foil width and thickness it can accept. Overall length is 1.625" (41.28mm). These dimensions are the key fit check: the terminal must match the foil ribbon's cross-section and the available clearance in the assembly.
Fit and cross-reference notes
This terminal belongs to the Termi-Foil series, which includes other double-face terminals with different crimp areas and overall lengths. The base product number 5194 covers the family — the full 51943 suffix specifies the exact foil crimp area and finish. No direct pin-compatible alternative is listed; the closest match would be another Termi-Foil terminal with matching foil crimp dimensions, but the buyer must verify the crimp area and overall length against the BOM.
