Electric Random Orbital sander

Can an electric orbital sander like the one linked below be successfully used as an alternative to an air DA for using sanding discs for deeper scratches?

I wouldn't do it. Look at the speed range for that tool, 4,000-12,000 OPM. Even the lowest speed setting is roughly the equivalent to speed "5" on a D/A polisher, mush faster than you would normally use to damp-sand paint.

I did a full cut and buff on my DD a while back and used 3"/6" 3M Trizact discs paired with my PC 7424XP and it worked absolutely beautifully. I would suggest doing your final pass (3000 or 5000 grit) with a small throw finishing DA though. I used my pneumatic DeWalt palm sander for this. IMO if you're going to be paying for a sander and already have an air-DA, you should just get a PC. Capable, well-built tool and can be used for polishing to perfection as well, which the linked tool cannot.

Thanks for the advice.
I am so new to this. I thought a higher speed would be better. ��
Sadly I don't have an air compressor.
Could i use my rotary polisher or is a DA more prefereable?

I would not recommend using a rotary for any type of cutting, unless you're intending to strip to bare metal for a respray. Lol. The action of the DA is much more gentle than a rotary. If this is your first time sanding clear coat, I would highly recommend that you research THOROUGHLY how to wet sand by hand/by machine and make sure that you understand just how thin the clear coat on a factory paint job is. Wet sanding should not be taken lightly, as if you break through to the base coat, the only repair method is a full repaint of the panel. There are many great resources on AGO about this topic. Just do a search for wet sanding or machine sanding clear coats.
