Can I replace capacitor with higher capacitance?
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.
Can you use a bigger capacitor?
Larger than needed microfarad values will not cause much of any problems (especially for a start capacitor). A larger than needed run capacitor will not have any real affect. Depending on the cap and motor it could improve efficiency or decease efficiency very slightly.
What kind of capacitor do I need to replace a 250 Volt Radio?
For instance, it is fine to replace a 250-volt rated capacitor with a 450-volt one. Almost all of the capacitors that I buy are rated for 450 volts. A few capacitors may require a higher voltage rating, such as 500 or 600 volts. Don’t waste money buying capacitors with voltage ratings vastly higher than the originals.
Can a 30 year old electrolytic capacitor be replaced?
While you may be able to reform your 30 to 50 year old original electrolytics, they may not perform as well as when new. There may be a partial loss of capacitance, or there may be excessive leakage (the caps get really warm), or both.

Can you change the value of a capacitor?
Actually, in many cases, you can swap significantly different value caps, especially interstage coupling caps. Capacitors usually have a 10-20% tolerance anyhow Click to expand… Second, some of the values you’re suggesting are dramatically different, .1 to .15 is 50% higher, big difference.
