Comparison

3 numbers are listed with 12257 in the makers' documents. Each pair is read against the substitution rules: same duty, same section count, capacitance within the run band or the same start range, and a voltage rating equal to or above the original's. Each listing is its maker's and the reading is this site's. Neither is a guarantee that the two fit the same place.
