This is a common capacitor size and type, and broad line distributors such as Digi-Key almost certainly have an exact replacement. The lead spacing is an important dimension to limit the search. DK has 15 different models in stock.
For most standard motors, a run capacitor will have a "tolerance" specified describing how close to the rated capacitance value that the actual value may be. This will be usually +/- 5% to 10%. For most motors, as long as the actual value is is within the 10% mark of the rated value, you''re in good shape.
Power Tips: How to select ceramic capacitors to meet ripple
add an additional capacitor or capacitors to meet ripple current requirement. Since Capacitor A has the lowest I RMS-to-C ratio, the added effective capacitance, C additional, should be greater than that calculated with Equation 8: C a ddit iona l ≥ 3.615ARM S −
