Rubycon MBZ availability/replacement?

[Kleist]

Hi Everyone,

I have a DFI board with a bunch of blown chemicon KZGs which I would like to replace with Rubycon MBZs but I cannot find them in stock anywhere, are these still for sale?

Are there any good replacements for the Rubycon MBZs?

Thanks!

Please post pics of your board.

EDIT: Ok, you made a different thread here: https://www.badcaps.net/forum/showthread.php?t=58686

MBZ / MCZ are discontinued years ago, if you see any on sale they are past it or fakes.

replace them with polymer caps.

I am somewhat hesitant to replace them with polymer caps not knowing enough about the implications on the circuit, I would rather a direct replacement.

Are there no more good electrolyte aluminum caps being sold?

I looked into the Panasonic FM already but they are not the same size as my KZGs.

new old stock is all there is for MBZ/MCZ. what value are you looking for?

Hi Topcat,

What do you mean by value? How long do I want them to last?

This motherboard (DFI Lanparty NF4) is more than 10 years old so whatever caps I put on here will probably outlive the rest of the components. That being said I would like to convert this into a small home server so the uptime will be near 24/7 and it will accumulate a lot of hours relatively quickly.

Did you have anything in mind?

I now realize that by value you probably meant what capacitance and voltage I need...sorry it was a long day at the office

I would ultimately like to change all the chemicon caps on the board, here is my shopping list:

Visually Bad:
KZG 1500uF 6.3V (8x18mm??): 2
KZG 470uF 16V (8x11.5mm): 7

Visually OK:
KZG 1500uF 16V: 5
KY 1000 uF 6.3V: 3
KY 100uF 25V: 14
KMG 470uF 6.3V: 2

Those wont cause you any trouble.
