Capacitor question??

(1/2) > >>

wadmancpu:
When choosing a replacement capacitors I have found caps that match capacity, voltage, ect but are sometimes physically smaller or larger. My question is: is there any other factors regarding physical size to consider other than fitting the board or if all the specs are the same can a physically smaller or larger cap be used? Thanks.

stmdude:
Pitch would be the most important physical factor. Pitch is the distance between the legs of the component.

ebclr:
Capacitors must be chosen according to the application, same capacitance and same voltage  means very little, Have a lot of another points that needs to be evaluated, Capacitors are more complex than womans

wadmancpu:
Yes, I understand your point about pitch. Maybe I should reword my question. Does the physical size of a cap make any difference in performance or function all other things being equal? I understand there's a lot to this stuff but as far as swapping a cap on a board if everything but the physical size were the same, and it fit on the board, will a different physical have any impact?

Kirkhaan:
I would be a little supprised if everything is the same at smaller size.
What about the rated ripple current and basic lifetime for example?
