How do I make components of a part into individual, separate parts?

I received a part from a colleague that has many components and I need one specific component for my own project. How do I make components of a part into individual, separate parts? Thank you.

It really depends on if you are dealing with a single body part, a multi body part, or an assembly.
If you post a screenshot of the part with the feature tree visible, I'm sure we'd have a few good ideas.
If you can't post a photo because it is super top secret, then I'll suggest using the Split tool. It will slice the part into multiple bodies. There is a good example in the SolidWorks help, see Split and Save Bodies
