URGENT REPAIR Are power/volume sensors and flex cables interchangeable

We use the tablets (DRAGON TOUCH MX10) as teaching tools for children due to their affordability and decent functionality for the price. unfortunately the first thing to break after the screen is the power/volume strip. Can anyone please tell us the model # for a replacement part. If not factory part, any compatible sensor would do. Our budget is extremely limited. any assistance will be welcomed. Please see pic for clarity.

ANY ASSISTANCE WILL BE APPRECIATED
