content: IME purchasing anything on ali is 50/50% chance of a bargain, or fake/poor quality items.Even when using sellers that I've used before!

content: The Chinese have a love for gold color. Anything with gold color is an automatic suspect. Not sure if they realize that.

content: Quote from: Helio_Centra on October 16, 2023, 03:23:48 pmI would not have much expectations about getting genuine parts from aliexpress but your post does not explain anything or show any proof. FWIW price is about the same as from Mouserlink. So on the face value of this listing parts likely are genuine.

content: Quote from: wraper on October 16, 2023, 04:24:29 pmReal Nichicon gold caps say "Fine Gold", and they got the fonts wrong. And the Farad rating is below the negative band not above it, and the temperature rating is below the Farads. The fake ones don't even tell you the temp rating.

content: These are FW series, not FG. If you see "Fine gold" on these, they're fake.

content: The replacement series "UFW" and "UFG" are in the Mouser catalog.It looks like Nichicon are now pushing the "UKW" series for audio applications.

content: Quote from: TimFox on October 16, 2023, 07:01:10 pmThey are not replacement series. All Nichicon series now start from "U" but it's not printed on actual capacitors.

content: Clarification: I meant the series that replaced the "FW" and "FG" series when you look them up in Mouser, etc.(Reply to Bud, who couldn't find "FW" and "FG" on DigiKey.)Nichicon used to list them as "FW" and "FG" in their literature.Now, they list them as UFW and UFG, and Mouser no longer lists FW and FG.

content: Here is a photo of digikey (bottom) to ali (top):As wraper says, visually they look identical, that alone is not enough to call fake. We'd need some measurement data.
