I agree with Morgana~

Basically there are no standards such as one finds with desktops. Please look here:

Now, you can probably get a generic component that is not made BY Toshiba, but you have to be sure that it is made FOR Toshiba. Not only that, but for the exact model that you have, as manufacturers aren't even consistent within their own product ranges.

Basically the problem is that the component is integral, rather than a peripheral. Unfortunately this results in greatly reduced production quantities and a much higher price.

Good luck
