What are the chances that plague capacitors are still in stock and being sold?

depends on your source - ebay probably cant be trusted.

^This, they should be well out of the inventory of major suppliers by now (DigiKey, Mouser, Newark, etc.). But I'm sure there are some still kicking around somewhere. Ebay is loaded with counterfeits as well as old inventory.
And while the true "plague era" caps should be largely gone by now (there is a good chance that most remaining would have bloated in storage by now, and if not the likely will quickly after power is applied), there are still new production sub-par caps out there that aren't reliable (particularly from the "less reputable" brands).Comment

I was hoping to hear that the manufacturers bought back all defective caps but it's more likely that they were sold.
Yes. Amazon and Ebay are bad for counterfeits, especially obsolete semiconductors, which they always have readily available.
I don't see much on Cornell Dubilier caps. I used quite a few and still recommend them. Is there a reason they aren't commonly mentioned? Quality? Price?
I deal with a lot of people (tech support) who blindly replaced capacitors (many plague caps) in their beloved collections (mainly amplifiers) and put them into storage. It's a shame that many will be damaged by leaky caps when the originals would have done no damage.Comment

I'm not aware of any such buybacks (and only the more reputable manufactures would even consider such a thing), but even if that did occur, defective/recalled products often have a way of "leaking" out into the wild (often claimed to be disposed of but smuggled out of the factory/warehouse and resold instead).
I've used them before with no issues, and they are generally regarded as a good/reputable manufacture. The main reason they aren't commonly mentioned here is likely that they aren't a major player in low-esr/computer grade caps which are the most common subject of posts on this forum.

It wasn't too long ago when I saw a bunch of (NOS) Rubycon MFZ (the 6.3V 2700 uF variety that like to bulge in storage / without use) on eBay - maybe about 3-4 months ago.
So yes, you can still find "plague" -era Japanese caps. Same with UCC KZG series. In fact, some sellers are unaware of this and even have pictures of their stock on which you can clearly see some of the caps bulging and/or leaking.
As for crap-cap brands - those are still sold everywhere and will likely continue to be sold for many many more years, if not indefinitely. Same with garbage (counterfeit) silicon parts.Comment

Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be... -
I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
