Can I replace a start capacitor with a higher uF?

An electric motor start capacitors can be replaced with a micro-farad or UF equal to or up to 20\% higher UF than the original capacitor serving the motor.

Is it OK to use higher voltage capacitor?

You can safely use 50V rated capacitors for all of them as long as they will fit. The voltage rating of a capacitor is the maximum only, they will work fine at any voltage less than or equal to this. Higher voltage capacitors have a lower ESR anyway, so you could improve the performance that way.

Can I replace a fan capacitor with a lower uF?

Can you replace a start capacitor with a lower uF? – Quora. But of course you can. It might not work, it might damage something else, but you ‘can. ‘ Replacing with a slightly higher uF should be fine however.

Does voltage matter on capacitors?

The voltage of a capacitor is proportional to the charge stored in the capacitor. For example, if your voltage source is 9 volts, you should choose a capacitor that is at least double the voltage, 18 volts or even 27 volts to be safe. AC or bipolar electrolytic capacitors have two anodes connected in reverse polarity.

Can I use a 50V capacitor instead of an 25V?

If you are using a 100uF 50V cap to replace a 100uF 25V cap, that is generally completely safe to do. Replacing a 50V capacitor with a 25V capacitor is a bad idea. The cap will probably fail, dramatically, in short order.

What happens if you oversize a capacitor?

The higher the MFD of the capacitor, the greater the stored energy and the greater the start winding amperage. This is why oversizing a capacitor can quickly cause damage to a compressor. By increasing the current on the start winding the compressor start winding will be much more prone to early failure.

Can I use 16v capacitor instead of 25V?

The maximum voltage you can deal with is what the voltage rating is. Make sure you know what you are dealing with. If you use a 25v rated cap, never exceed 25V. Don’t exceed 16v for a 16v rated cap.

Can I use a 50V capacitor instead of a 25V?

What if I connect a 3.15 ΜF capacitor instead of 2.5 in a ceiling fan?

Fan will run faster and consume more current. If the windings can not carry the increased current the fan can overheat and windings burnt.

Can I use 63v capacitor instead of 50V?

Yes, you can safely use a 63 V capacitor as a replacement for a 25 V capacitor. It is always safe to select a higher voltage rating for a capacitor (although this may be physically larger and more expensive).

Can I use 16v capacitor instead of 50V?

You can always substitute a capacitor with a higher voltage rating into a circuit designed to use a capacitor with a lower rating.

Can I use 25v capacitor instead of 16v?

Yes. The voltage rating is the naximun that the cap can handle. 25 is higher than 16 so you are ok.
