Are these capacitors interchangeable?

I want to repair a PS3 Phat that has 8 times NEC / TOKIN 0E128 capacitors. According to the Internet, these should be replaced with tantalum capacitors with 470 µF and 6.3 volts, unfortunately these capacitors are terribly expensive and the PS3 is probably no longer worth it.

However, I have found electrolytic capacitors that I believe have the same values. Can I take these electrolytic capacitors:

To replace the tantalum capacitors? I have enough space in the case, if not, I just pull a cable to a place where I have space. I just need to know if I can take it.

Since it is unknown here what these capacitors are used for, I can't answer that.

Electrolytic capacitors are polarized, so they can only be used for DC voltage, with NF quality also suffers.

Tantalum capacitors are bipolar and also better for NF.

Fr

So the capacitors are probably responsible for the CPU and GPU voltage. Does that help?

Oh yes, what is NF?

Pe

If they are only used for smoothing, then yes. However, it should also be clarified why these capacitors failed and why exactly these high-quality capacitors are used there. Electrolytic capacitors are normally used for smoothing.

NF is low frequency, i.e. For sound and music.

Tantalum capacitors are bipolar

Not necessarily. There are also tantalum capacitors

bl

You can't say that exactly. Tantalum electrolytic capacitors A. The advantage of higher temperature stability. Could be that this is important here.

Fr

Ok, sorry, was wrong information. I have now been told that it is a PS3. There are 8 of them on it, they will probably just break over time. Tantalum capacitors are probably already installed in the Superslim models, instead of these NEC / Tolkien things.

The capacitors probably the "filtering and providing the necessary current" (filtre and provide the necessary current).

Fr

Or should I simply replace them with NEC 0E128 capacitors again? You can also get them from china…

Pe

Well then, there are also electrolytic capacitors - pay attention to the polarity!

Fr

For real? Cool! This now saves me a lot of time and money.

Isn't it a problem if I put the electrolytic capacitors somewhere else and then connect them with a cage? Because there's not enough space for electrolytic capacitors on the PS3, but elsewhere.

PS: Are the capacitors shown sufficient? Especially the ESR etc? I can also take something like this:

Hi, this is a PS3, it has 8 of the things for CPU and GPU, for filtering and providing power. I have the following capacitors in mind:

https://www.conrad.de/de/p/yageo-sy006m0470b3f-0811-elektrolyt-kondensator-radial-bedrahtet-5-mm-470-f-6-3-v-20-x-h-8-mm-x-11-mm-1-st-442662.html

Pe

Yes, the capacity and voltage should be the same. Sure, they used this NEC 0E128e because they are so small.
Can also be installed with not too thin wire and lock these electrolytic capacitors!

Fr

Ok, thank you very much for the help. I would then probably take the cables that are normally used for jumper cables / Dupont cables. I don't know the cross-section right now.

I think it's not a problem that I now have 6.3 volts instead of 2.5 volts?

Pe

The tension just must not be less.

Fr

All right. One last question: the SMD electrolytic capacitors have a height of 7.7 mm. This is less than a cm, and would probably even fit where the old ones were. Or is that just the height of the black part?

Ok, one more question, sorry, would you rather take the SMD or the others?

Pe

If you have space, the normal electrolytic capacitors are easier to solder - but you have to decide, good luck.
The height is given without the connections (as installation height).

Fr

Ok, I'll have a look at the place.

Fr

@AlterLeipziger Sorry, one more thing: Can I also use an electrolytic capacitor with 16V and 470 µF? Are these in stock at Conrad? Or is that too far from the 2.5V?

bl

Are you sure they fit? Tantalum capacitors are mostly found in SMD form - which would make sense in a PS3.

bl

That in turn doesn't matter. The specified voltage reflects the dielectric strength. That means that the manufacturer does not guarantee that. More that the tension doesn't break through. You can also use 63V or 250V types as long as the design fits. It just can't be lower.

Fr

That's why I'm asking. Tantalum capacitors with 470 µF are really expensive…

Fr

Ok, perfect.

Ch

First question, are the original capacitors in the SMD design, or are they the wired standard spheres of smaller dimensions?

Tantalum elk are mostly used because of their smaller size and lower ESR. You could also use normal electrolytic capacitors with the lowest possible ESR.

Fr

The originals are probably SMD, such strange things, look like memory chips
