I don�t know of a way to make components unusable without adding restrictions to the vehicles they are to be used in. Also if they can be made unusable that would just make for a mod doomed to failure. Ask yourself if you would really want to play a mod that clutters the ship design screen with components that you aren�t even allowed to use? What you are describing is closer to a semi-generational component. Any generational mod must, by nature, have the components removed from the list.

If you can�t imagine what I am saying start a game of SE4, give yourself all tech to start with, go to design a ship, then make sure the �Only Latest� button is not selected. Now try scanning through all that. That is an example of what I am coining as semi-generational. Keep in mind this is an example of semi-generational. Meaning the components may be outdated but you can still use them. In the example above and in your question the components aren�t usable. They are just cluttering up space, in other words almost semi-generational.
