Questions about sizes and voltage

[ebaygeek]

I'm gonna recap my ol' xbox 360 mobo however i'm a bit curious about the caps in your store.

These are the caps i need..

Rubycon 1500uF 16v MCZ
Rubycon 820uF 6.3v MFZ
Nichicon 220uF 10v HE(M)

Well i see you got the 1500uF one, however the 820uF you got is 'MCZ' while i need 'MFZ', is there any difference between them? I am by no means an expert in the field and the only difference i could find is that the 'MCZ' is 12mm in height and 'MFZ' is 24mm in height..

I'm also curious if it would be safe (would it even work?) to use a Rubycon 220uF 16v YXA instead of a Nichicon 220uF 10v HE(M)?

Thanks in advance!

The Rubycon MFZ series is an ultra low ESR series and also a 105 degree cap. Yes it should be ok to use the MCZ series in place of the MFZ. The main thing is that the size fits, both physically and in specs to where it will be placed. It is OK to replace one with a different cap that is say a little smaller or longer or wider or thinner as long as it does not interfer with the other components in the device. Both MFZ and MCZ are low ESR caps so they can be interchanged.

I have tried looking up the series and it seems to be hard to find info on. I have found very few sizes in the MFZ series so it might be a custom order size.

Yes it is OK. The 220uF is what is really important. The 10v part is kinda like a circuit breaker. that is the max amount of load it can handle before it blows. So it is safe to put in a 12 or 14 or 16 volt in place of a 10v, but you should try never to go down to say a 6.3v cap. It is best to try to always try to stay at the same volt or a little higher.

Seeing as everything is fine I'm going to place my order right away then, thanks for your answer!

Re: Questions about sizes and voltage

Nichicon HE is a low ESR cap.

HE Specs for 10V 220uF:
Impendence (ESR): .22 ohms
Ripple Current: 340 mA

When looking for a replacement, you want to find another cap with similar or better specs. Lower ESR is better, Higher ripple is better.

Rubycon YXA is a good cap, but it is not a low ESR cap. So, it may not be reliable in the application you will use it. Rubycon YXA has a ripple current of 220 (worse than the HE). ESR is not even listed in the YXA data sheet as it is not a low ESR cap.

Going from 10V to 16V is not an issue, as this is a voltage limit if you will. However, going from a Low ESR cap to a standard cap may be a problem. For the replacement for the HE, I would be looking at Rubycon YXG, ZL; Panasonic FC; Samxon GT.

I found a local retailer that sells Sanyo 10ME220WX with the specs
Voltage: 10 V dc
Capacity: 220 uF
Ripple Current: 0.405 A @ 100 kHz 105°C
ESR/Impedance: 0.13 Ω @ 100 kHz

Would it be better going with those rather than the Rubycon YXA then?

Based on my basic knowledge, yes, I'd be more comfortable using the Sanyo WX caps than the YXA. The WX is even lower ESR and higher ripple than HE, so it will be an upgrade.

Re: Questions about sizes and voltage

sorry, missed that about the YXA part.. yyonline is right.. those are regular caps. like he said best to go with low esr and higher ripple ones. cant believe i missed that..

Very well then, thank you!

No problem, no damage done and everyone makes mistakes so it's ok.

Anyway thank you both for your help, much appreciated!
