Most of them are replaceable. As mentioned earlier, if the voltage capacity of the capacitor is close to or the same, the capacitor can be replaced. Attention should be paid to the following two situations:

1 electrolytic capacitor is replaced by tantalum capacitor: tantalum capacitor is not resistant to high temperature and easy to catch fire, so it cannot be used in industrial occasions or high temperature environment.

2 Electrolytic capacitor is replaced by ceramic capacitor: electrolytic capacitor has a certain ESR, and ceramic capacitor has a small ESR. Some special circuit designs need to ensure the use of ESR in a certain range of electrolytic capacitors, but when using ceramic capacitors, ESR may be too small to cause some oscillation; Especially in the output stage of power chips, there are certain requirements. This place must meet the requirements.
