Recplace axial capacitor by radial cap?
« on: February 13, 2021, 11:20:52 pm »
As a newbie to repairing old stuff I am in the progress to make some homework before I will in the next weeks plan to recap some old equipment.
Here I have some stuff that originally uses axial electrolytic caps, but my favorite supplier does not carry exact replacements for them.

Question is here: What are the drawbacks of replacing some old capacitor with a new radial one?

I could think of vibration (may be fixed with some glue or goop or similar stuff) and issues to get the wires right because of the space the former axial cap has used...

Are there other issues like heat dissipation, different ESR or other things I would have to be on the lookout?

(My supplier carries Panasonic caps that I would like to use, and a DER EE DE-5000 is just ordered to check for good components)

I think the capacitors are the same, or so close that you don't have to worry.  Of course the radial is a cantilever and needs support to avoid fatigue of the leads.  Cementing it down ought to be okay.  Use silicon rubber or a clamp if it's heavy.

It looks a bit sloppy and often one of the leads won't be long enough but if you can make the thing fit and mechanically secure it there is no problem.
