You are looking for dedicated brand parts.
Did you look at the manufacturers sales representatives, distributors...?
On the manufacturer's internet site there should be a list.
But as schmitt trigger said, you need to know the working voltage.
you'll probably also want an idea of the case size and shape, temperature range, etc.
There were upwards of 1500 different voltage ratings, cases, footprints, etc etc for the 47 uF Nichicon.
Also, there are a lot of capacitor manufacturer's who make a good product.
If you know the parameters, you can get the same capacitor from a different manufacturer.
