Set listbox to show specific part of an equipment

[ZidonX]

Hello,
I'm trying to solve a problem with my userform.

I have a list of equipment and a list of specific parts of this equipment in the same Excel Book.

I want the "select part" listbox to show specific parts as i can modify the tag entry in the first textbox.

Here the Equipment List, the Parts List and the userform format:

I would appreciate if you can share the VBA code.

Thanks for your help.
