No. If you used the elongated oval holes in the J-Stik plate, you might be able to use the same for the T-Stik. However, the 'main' round holes in the J-Stik do not line up with the T-Stik holes.
My 'test' control panel has J-Stiks in it...I had to drill some extra holes in order to try out the T-Stik.
