I have a DVR that I was replacing the fan in, and noticed one of the capacitors on the power supply board had failed (all others are fine). It was slightly domed with the bottom pushed out. It's a Rubycon 2200μF 10V MCZ - so it's ultra low ESR. Since these have been discontinued, there isn't a direct replacement. I've tried finding something with similar specs, and what I think will work is the RNL series from Nichicon - specifically this one. It's the same capacitance, slightly higher voltage rating (which I understand is fine), and the diameter is the same, slightly shorter (height isn't critical here anyway). I think the ESR rating is okay - the Rubycon is rated to 9mΩ and the Nichicon for 8mΩ. It's the ripple current rating(s) I'm not sure of, and possibly other things I'm not aware of/overlooking.
Basically is this a good substitute, or does anyone have a better recommendation?
Thanks in advance to all that respond.
