Electronics, replacing an 8 pin DIP with a 9 pin DIP

[littlepigboy5]

I have a design I want to make here, http://www.instructables.com/id/Frameless-Laser-Harp/step4/Wiring-it-all-together/ , if you go to the first page(i linked you to page 4 because that is where the diagram is), you can see that the dip needed is a uln2003a.  would it work if I used a uln2803 instead?  I don't really know how dips work, so I am looking for somebody who knows that answer.

Thanks,

According to they datasheets, they seem to essentially be the same thing, but the second one has one more transistor for one more signal. Just make sure that it is wired up correctly.

I would have checked the datasheets, I just didn't know what to look for.  The motor I am using has 4 wires not 6, so just to give me an idea, would I hook up the four wires in the same way the four colored wires on the diagram or wired, but there will just be 1 extra pin on the end of the dip?
