Hello,
The link provided does show what the voltage code is. I would say if the JZA is on the bottom. The voltage would be the 6.3v like this link: SMT Electrolytic Capacitor with no Voltage Rating - Passives / Capacitors - Electronic Component and Engineering Solution Forum - TechForum │ Digi-Key (digikey.com)
This was in the link that Nathan provided. Though I also agree with Hutch. You know the 47uf. You can look through the list of options with tha value . You can narrow down by the smd 47uf . Click in stock and apply filters. Then measure what you have and narrow down by size. Hopefully this new link helps.
