Hi, im building speeduino board and was wondering if i can swap BOM with electrolytic capcatior because it is hard to get tantalum one. uf rating does match but voltage rating is almost twice larger than one in BOMs.

As well i wanted to ask is it wrong if i replace diodes? i have 1n4004 and instead i would install 1n4007? would that be okay?
The voltage rating isn't too much of a problem but the capacitor on the output of the regulator must have the correct ESR rating, that is given in the datasheet.
1N4004 is OK, its a 400V diode rather than a 1000V diode and is more than adequate.
