Question; can I substitute the 1N457 diode for a 1N4007? Or are there any specific specs to the 1N457 that makes it more suitable?

No ,use 1N457 it’s a general purpose small diode,buy them by 100 ,it’s cheap
If I have to change ,I will use a 1N4148
A 1N4007 is a big diodé often use in PSU for electric rectification,voltage up to 700V

You can find the datasheet here :

I know, but I have a whole bunch of 1N4007's on the shelf...might as well use them if they fit the PCB.
so, other than being over specced (too havy) , is there another reason for NOT using the 1N4007?

The 400x série Rectifier diode have a different threshold and voltage drop than a Signal diode like the 1N457
The 4007 could be fine in some place on the circuit but not in another.
