The only ones we believe are affected from that list are the AF11x series. Because they have metal cases which are meant to be earthed they are particularly vulnerable.

In theory it's possible for an tin based part to grow whiskers but a large tinned area of metal case is a much bigger hazard than small soldered joints.
