You can almost always replace a capacitor with one of a higher voltage. This is the limiting factor of a capacitor due to dielectric breakdown voltages that the manufacturer chose. Varying capacitance gets a little trickier. If the property of capacitance is used for power supply filtering, then it is generally fine to increase the value.
Once you understand voltage and capacitance, you can replace your capacitor using tools you already have at home. There are several reasons why you may need to replace a capacitor. While most capacitors can last up to 20 years, using improper voltage can overwork the system and cause it to burn out early.
Yes, you can replace a capacitor with one of a slightly higher uF, but try to stay as close as possible to the original number and don’t go lower. Replacing a capacitor is sometimes referred to as “recapping a circuit board,” and it’s important to match the new capacitor up to the old one.
Replacing a capacitor is sometimes referred to as “recapping a circuit board,” and it’s important to match the new capacitor up to the old one. Both the capacitance (uF) and the voltage (V) should remain constant.
If your computer or electronic device is malfunctioning, you may need to replace the capacitor. You will need to match up the uF, although most capacitors have a 10 to 20% tolerance. This means that you can opt for one with a slightly higher uF, or capacitance rating, without any major consequence when replacing your capacitor.
It’s often a good idea to replace all electrolytic capacitors at once, as they degrade at similar rates. However, film and ceramic capacitors may not need replacing unless they show signs of failure. 10. Conclusion

Can I use a higher voltage rating when replacing capacitors?
Replacing a capacitor with something that has a higher voltage rating is always safe.

Sometimes it is also safe to use capacitors with a larger capacitance (Farads).
