Large electrolytic capacitors like these are virtually always used in situations where the value is not terribly critical, so going up by 50% or more in capacitance won't be a problem.
I have found that I can rarely find an exact substitute, but fortunately as technology has improved sizes have gone down so fit is usually possible, with two caveats.
1. Lead spacing is rarely the same. For wire leads this isn't too bad a problem, but tab leads are a bigger problem. You can substitute a wire lead part, or add wires to the tabs on the new part. Be sure to use large enough wire for the currents involved (use trace size as a guide if you don't know) and be sure to add mechanical support since the cap is no longer sitting on it's base.
2. Volumes have decreased but form factors change. The newer caps are often shorter and fatter than the one you are replacing. Be sure to check both dimensions for compatibility with the space you have to put them in.
Don't quit looking with the first choice you find that works. I have found 10:1 price differences for similar capacitors. Sometimes the price difference is due to a real quality difference, but often it is due to differences such as overstock, or a standard value which is produced in high volume or other difference which doesn't affect anything except your pocketbook.
