    220UF substitute with 470UF

    Hi,
    I have several Acer AL1717 monitors with blown caps; can I use 470UF, 25v, in place of the original 220UF, 25v?
    Thanks!

    No. Use the proper uF value. Doubling capacitance is likely not going to work.

    We just had one person replace the original bloated 470uF 25V caps with 1000uF 25V and the TV stopped working. He then replaced it with the proper values (i.e. 470uF) and the TV works.

    I suggest Panasonic FM for replacements.

    PS. Make sure the diameter and height fit.

        I agree with retiredcaps. - Use the original uF value.
        .
        There is no way to guess what changing uF will do unless you know that particular circuit at schematic level like the back of your hand.
        If you don't then either:
        - Use the original value.
        - Draw out the schematic and do all the math to see what the uF change will do.
        .
        Both Panasonic FM and FR are great choices for this.
        Their specs are nearly the same but the can sizes can be different for a given uF so that gives you more physical size options if space is a problem.

          I was hoping to use them, because the originals seem like junk-- but went ahead and ordered them anyways.
          Hope they last longer than the first batch! Thanks!
