Different Sizes Of Electrolytic Capacitors
If the original size of an electrolytic capacitor is bigger than the one that you want to replace (smaller in size but with the same microfarad and working voltage), will the replacement capacitor work? Some may say that it will work but would not last. Okay, my answer to you is that it will work and will last depending on what brand of electrolytic capacitor you are using. I have tested many (smaller size capacitor than the original) of them and so far no problem with it.
Different manufacturers produce different sizes of electrolytic capacitor, as long as the value and the working voltage is the same then you can use it. However, i came across a case where i installed a low quality capacitor (sometimes hard to differentiate between a good and a low quality capacitor) and the moment i powered On it, the capacitor produced a “pop sound” and i could see smoke coming out from the cap. I bought quite a number of it and after replacement from the same supplier, the capacitor never blow again.
