FZ83 6.3v 1500 replace with 6.3 2700uF

[LinsonChan]

can I use a 6.3v 2700uF from an Xbox360 and replace a 6.3v 1500 from a vga?

Re: FZ83 6.3v 1500 replace with 6.3 2700uF

what series is the 2700?
it will be a bit tall.

He wants to use Rubycon MFZ to replace Sacon FZ.

No.

so it wont work?

There's no guarantees when you change capacitance that much. It might work, it might not work, it might damage other components, etc. It's also not a good idea to reuse capacitors unless you know the voltage of the circuit it was on, as capacitors reform to a lower voltage if used on a lower voltage circuit.

Your best bet is to use the correct replacement. Here is one option:

There are other options from other vendors as well. When selecting your replacement, make sure that it has at least 1800 mA of ripple handling ability and 22 mOhms or less ESR. Those are the specifications of the original capacitor, and you want your replacement to meet or exceed them.

MCZ is not the correct replacement, MBZ is closer to it. Samxon GD will also work.

I wouldn't use much more then a 6.3 1800.

No, it will probably work just fine.
It all comes down to how you want to do it.
If this card is important to you and you definitely want to get it working properly, then buy the right caps.
Otherwise, if you don't really give a crap about the video card that much and just want see some results, put those MFZ caps and let it rip. As yyonline said, though - there's no guarantees. Most likely it will work fine, though. Almost anything should be better than those Sacon FZ caps.

MCZ is not the correct replacement, MBZ is closer to it. Samxon GD will also work.

MBZ works as a replacement for 8mm FZ. 10mm FZ is another story.

6.3V 1500uF MBZ does not have enough ripple handling ability to replace 10x12.5mm FZ (1540mA for MBZ, 1800mA for FZ). Besides that, they don't really exist anymore in new stock.

GD still exist, but are identical in specs to MBZ...so not enough ripple there either.

Samxon GC is between MBZ and MCZ spec-wise, and is a near perfect match in 10x12.5 (1760mA...2% off from 10x12.5 FZ). But...Topcat carries 6.3 1500uF GC in 10x16, which is tall enough that it may cause interference with cards in adjacent slots if they're populated. The larger GCs specs are even further off than the MCZ is to FZ due to the larger can size (2280mA for the taller GC vs. 1800mA for FZ)...

I use MCZ to replace FZ all the time. MCZ is rated slightly better than FZ (1960mA for MCZ, 1800mA for FZ), but the 9% difference certainly isn't drastic enough to cause any issues.

Re: FZ83 6.3v 1500 replace with 6.3 2700uF

Hmmm... But that particular Rubycon is also at least 16mm tall, so the 16mm GC should fit.

I guess he can mismatch the ESR if it is going to give him better ripple suppression.

What the heck, local electronics shop told me that they could not get 6.3v 1800ufs, Discontinued. Wow, I get lots of them that are bad.

Re: FZ83 6.3v 1500 replace with 6.3 2700uF

The choices now are Samxon, Nichicon, and Suncon[Sanyo].
err,,,, at least in the commonly seen brands.
Suncons best series is WG which is a match to MBZ.
To get lower ESR you are stuck with Nichicon and Samxon.

NIC Components might have something but I've never seen their products for sale except on eBay from dealers I don't trust.

Re: FZ83 6.3v 1500 replace with 6.3 2700uF

I'm sorry but to say there is any resemblance of Sacon FZ and their datasheets numbers is just pulling a long one.
In any ordinary case, then yes, it would be important to choose appropriate caps

But in the case where a card has a Sacon FZ, and works anything at all as it should. Then it for sure means this card is not picky about ESR, Ripple or Capacitance

Let's just say for a "normal" capcitor I would stay within 20% of most values, and certainly only in the "better" direction (i.e. higher capacitance & ripple, lower ESR)
But when it comes to Sacon and the total utter crap they produce I think a ripe orange fruit would offer better specifications!

Sacon FZ never came in 1800uF...

1800uF are still available from badcaps.net store and mouser.com in the USA.

@PCBONEZ, you missed panny. These would work too to replace 1500uF FZ caps (I know this seller, they ARE genuine).

He may have sent you genuine merchandise, but there is such a thing as a selective scammer. I would not buy caps from China period. Except from Big Joe.

Also I want to point out that I have seen Panasonic FC fakes that were very difficult to tell apart from the genuine.

You're probably right however the caps are chosen for an application based on their advertised specs.
If you want to ensure the device works as the designer intended it to it is best to choose caps that have specs at least as good as the specs for what you found there, even if the quality is crap..
.
Some of the FZ have specs better than MBZ.

Yes I did... - Thanks.
