    Replacement cap help

    Hi,

    I am wanting to replace a burst cap on a dell motherboard but i'm struggling to find a replacement.

    it is a - 820uf 6.3v diameter = 8mm length = 20mm

    please does anyone know where i can get 1 from (pref UK) or can I substitute it with something else?

    Thanks

      This is from digikey

      but Panasonic FM is widely available from the big UK internet sites.

      It is 8x15mm.

      Panasonic FM is low ESR cap.

          What grade is the original cap? Are there any other markings on it that would indicate its series?

          Rubycon/Nichicon/Chemicon made custom size "extra tall" 820uF caps for many P4-era boards. The custom size 820uF cap has lower ESR and higher ripple current limits than a normal 820uF cap. If your cap is one of these custom size ones, FM would be an inadequate replacement. They don't make the custom size any more, so you're left with the option to use a poly cap on it, or find some new old stock of the custom size capacitors.

          But...let's get more info about the original before jumping to that conclusion.

              Macbook Air M2 A2681 Kernel panics after screen replacement
              by reformatt
              Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

              It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

              Unknown transformer : how to find a good replacement part ?
              by the_rem
              Hello guys,

              I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

              I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

              PS4 controller left stick potentiometer replacement issue
              by ezenia
              Hello,

              Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

              So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

              I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

              Macbook pro logic board replacement parts quesion
              by boosti45
              i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...

              klipsch kda-500 amplifier suitable power supply capacitor replacement ?
              by r2digital
              I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...
