    Question about capacitor size with same rating

    If the capacitor rating is identical but if the replacement capacitor is smaller in size, does it matter?

    Re: Question about capacitor size with same rating

    If by "rating" you mean capacitance and voltage, it often does matter, because the temperature, impedance, and ripple current rating often matter a lot.

    On the other hand, if you are comparing a 30 year old capacitor and a 2021 manufactured capacitor of the same capacitance, voltage, temperature, impedance, and ripple current ratings, the newer part might be smaller, due to technology progress.

      I'm looking to replace Rubycon 2700uf 6.3v MFZ series and 1500uf 16v MCZ series on an old xbox 360. I couldn't find a datasheet for either rubycon series. Which capacitor brand and series is appropriate for a game console? Would a capacitor labeled for general purpose and with low impendence work?
