Hi, in general, when replacing capacitors, which values (be it capacitance, voltage, ripple current, leak current, ESR, e.t.c.) must be followed and which ones are ok to be different? This mostly depends on the particular circuit. However, if the part will fit physically, a higher voltage rating will be ok. and lower leakage is ok.
When choosing a decoupling capacitor, several factors come into play:. Operating Frequency: Higher frequencies require capacitors with lower ESR and ESL (Equivalent Series Inductance). Required Capacitance:
I''m replacing the foam surrounds of the woofers in a vintage pair of speakers - Sound Dynamics 300ti. While I''m at it I thought I''d replace the crossover capacitors: Do I need to pay attention to the orientation / polarization (not sure of the correct term) when I install the new ones? Should...
Before replacing a capacitor, make sure that it has a higher voltage rating than the original one. A lower voltage rating can lead to poor performance and even component failure over time due to the increased stress.

This mostly depends on the particular circuit. However, if the part will fit physically, a higher voltage rating will be ok. and lower leakage is ok.
A drop in capacitance value is another sign of a deteriorating capacitor. This usually happens due to age, but can also be caused by excessive heat or current. In this situation, replacing the capacitor with one that has the same voltage rating and a higher capacitance value is usually the best course of action.
Use an insulated screwdriver to short-circuit the terminals of the bad capacitor. This discharges any stored electrical energy and reduces the risk of electric shock. Remove Access Panel or Casing: If necessary, remove the access panel or casing covering the capacitor.
No, it is not necessary to replace a capacitor with an exact replacement. In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw.
