Confused on choosing the correct replacement electrolytic capacitor.
For example, on an Atari AR I board (built in the early 1980s), the parts list calls for two (2) 3300 uf Aluminum Electrolytic Fixed Axial-Lead 35V. The original capacitor PHYSICAL size are relatively large. When you go on modern parts suppliers, you can find capacitors that fit the capacitance and voltage specs, but their physical size can be significantly smaller.
I've read somewhere that you should choose a replacement that is exactly the same size, or very close, because the design is calling for the capacitor to support a high and constant ripple. A smaller physical size will get stressed out quicker and fail.
Is there another specification characteristics that I should be looking at on the datasheets that need to match to the original part?
