Can I use a 3300uf capacitor to replace a 2200uf on my motherboard?

Question

One of the capacitors on my motherboard has gone bad. It's a 6.3V, 2200uf cap. I've got a few 6.3V, 3300uf capacitors laying around the house, can I use one of these in it's place, or am I running the risk of damaging my motherboard by doing so?

Answer 1

You could probably use them just fine - most likely - but it really depends on which ones went bad and the archetecture around their use.

In short, you are running a risk, unless you know the exact use of them. It might be it's irrelevent, as related parts in the archectecure accounts for, or is irrelevent to, the discharge and it really doesn't matter what's there and becomes a matter of cost of the manufacturer- of which the smaller capacitor is cheaper, and a larger one lacks necessity or even use.

So that's the risk, unless you can get an archecture blueprint of your mb and discover what the purpose of the specific capacitors are and the requirements and tolerances of the connected systems.


All that being said -- It'll be fine. Almost certainly. But note the risk, as it depends on the archecture and which ones, etc etc, -- if you edit your answer with a specific board and then say which specific capicators have blown their cap, can give better advice.

Answer 2

This size of capacitors use in the power lines for filtering. Larger capacitors do this better, so, use it and don't worry

Answer 3

You run the risk of damage - get the correct part, but be carefull with replacement as surface mount component replacement can be tricky.

Answer 4

Yes to both
