Replacing Capacitors With Different Values Guide
Can I use a 450v capacitor instead of 400v? Yes, you can use a 450v capacitor instead of 400v as long as the other characteristics (such as capacitance and temperature rating) are identical. Increasing the voltage rating may help protect your circuit from higher voltages, but it also means that it can be more expensive. Can I replace a 370v ...

It'' s not only size and cost. There are properties that are different for each capacitor type, so in short : no, you can''t replace any capacitor with other kind ( if size and budget weren''t a problem). You probably won''t find an electrolytic when high precision is needed or very high freqs are involved.
Capacitor sizing for power supply
You only answered half my questions. 27Vac means that the capacitor will charge to a peak value of 1.414*27 - 2*Vf (forward drop of the rectifiers). Vf is about 1V for most large silicon rectifiers. So unloaded voltage will be ~ 38 - 2 = 36V. Under load, the capacitor will charge to a value less than the 36V, mostly due to the impedance of the transformer (caused …

What is the formula for how long a capacitor can power a circuit
For example, a lead-acid battery charges up to a maximum of 13.8V and is considered dead (can''t provide current anymore) when it''s 11.4V. If you are using a capacitor to power something, then you must treat it similarly: It doesn''t matter if your capacitor is truly dead when it''s 0V if whatever you''re powering requires at least 3V. $endgroup$
