Yes, Items made with parts are scrapped into 3 parts for the respective item. So you would get the 3 parts you're missing.

Unfortunately, You get 3 parts back regardless of the quality level- 3 for a Q1, and 3 for a Q5. So it's, best to only scrap lower quality items where possible.

As a side tip, rather than selling Q1 items that are made with item parts, it's actually worth more dukes to scrap them and sell the parts instead.
