I'd like to know how I could identify original nippon (japonese) electrolytic capacitors, like this one in the picture, from Chinese sellers in websites like aliexpress.



Here's an example: https://aliexpress.com/item/3289865...lgo_pvid=4dee33a7-ce0e-4b7b-b477-71464b7ca118

I need them for fixing a Sony Wega TV (CRT), but locally they're very expensive, so expensive that price is equivalente to dozens of general electrolytic capacitors. Also I'm not in the US, so I couldn't find any store in the US that would have a cheap international shipping. In shortly, I just need to know how to identify if they're fake or original.

 

Hard to identify is they are "real" or fakes. That is the problem with Chinese sellers. Even on Aliexpress, many are third party unknown suppliers. Some caps may actually be from the "original" factory, but failed quality tests and "fell off the back of the truck" on the way to scrap.
The most reliable way to get original vendor parts is to order from a reputable supplier, which does cost more of course.
If you have a known good "original", you can try to compare these ones to the original via testing, including things like leakage (self discharge) and the ESR.
The problem with fakes is that they don't meet the specifications, and may deteriorate quicker. Initial use the fakes may seem ok, but they may start to fail soon
