I am trying to replace caps on a Dell GX270 motherboard. I ordered some but when they came in they are taller than what is on the board. The height will not interfere with anything that I can tell. But I was wondering if there is any significant difference in performance or how they are supposed to work between a 6.3v 1500uF cap that is 10mm thick or wide and is 1/2" tall and one with those same specs that is 3/4" tall? Also should I just change out the caps that I can tell are bad? Or should I change all of the ones that are the size of the ones I can tell are blown? The only ones that have popped are this 6.3v 1500uF size. Thanks for any help.

Re: Does the height of a cap make a difference in performance?
Physical size does not matter as long as they will fit on the board and not interfere with anything
Although physically larger capacitors of the same value and voltage are probably higher quality."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Does the height of a cap make a difference in performance?
The different diameter capacitors can have slightly different values for various parameters like ESR, ripple etc. However they are within the same region as the thicker diameter ones (and they could be exactly the same). The only way you will know for sure whether there is a difference is to check the datasheet for the capacitors that you have bought.
However, generally there is practically no difference.Comment
