Replacing a capacitor
The capacitor in your datasheet is a low-leakage type with 0.002CV leakage maximum. That's about 10:1 or 20:1 less than typical electrolytic caps, and really is a red flag to my eyes that this is a coupling capacitor and not some kind of power supply part. The other oddball spec is the 125°C rating, which is either specified because the part is exposed to high temperatures or to get a long life (in theory, anyway since life is supposed to double for every 10°C below rated). 

Of course we can't tell from the part datasheet whether low leakage is an actual requirement, but it would be prudent to try to find a low leakage part. Nichicon has a good range of such parts. 

For example, check out UKL1H470MPDANA, UKL1J470MPD1AA, UKL1V470MPDANA, UKL1V470KPDANA etc. Unfortunately, none of those parts has a higher rating than 105°C. So you may have to make a judgment as to whether life or high temperature operation is actually a requirement unless you can find one that is same or better in all specifications. 

Other than that, it has to physically fit, have the same capacitance, same or better tolerance and same or higher voltage rating. ESR should be similar or less.
