Just to add to the great answer provided by my colleague @tech_ni The component in question is reference designator C6587 which is a 33µF 16V 20% Tant-Poly capacitor in a B3-1 case. It's a bit hard to find due to the B3 case. Based on the dimension of that case, you should find a suitable replacement [https://www.aliexpress.us/item/3256803857326990.html|on here] under the B 16V 33UF 336C tab. Or, you could find a close match (not an exact match ;-) just measure the solder pads on your board and use Mouser.com or Digikey.com to find a case that will fit those dimensions.
