It can fit but the fit is very tight and far from ideal. Even though the 7+ is thinner it is longer and wider. It will fit in with no modification and the charge port will work. However, it is not ideal. I sanded the corners on mine down a bit to help it fit better. If it is something you want to put in the dock everyday I would recommend not getting the new tab without the new dock. However, if you are only using it once a month on trips or something, then it should work for you.
