Fan capacitor replacement question
As long as the cap UF rating or micro farids are within 10% and the voltage is the same or higher it will usually work fine.
This is a bit smaller but it will probably work.
Mcm 2 wire ceiling fan 5,5uf 450 vac Ccb61. would be a better match

You can go higher on the voltage but not lower than the peak to peak voltage
120v x 1.41 =170 as an absolute minimum  higher is better and will last longer.
