Capacitance in AC Circuits

The capacitance value of 50uF is exactly the same and the 450VAC rated capacitor has a better tolerance. 330VAC implies its a "Starting" capacitor, 450VAC implies its a "Run" capacitor. As the nominal voltage of 450V is higher than 330V, you can use a 450V rated capacitor inplace of a 330V rated one, although the physical size may be different.
