Is there a direct replacement for the XA3S400-4FGG456Q?

No. The manufacturer's discontinuation notice states there is no direct replacement for the XA3S400-4FGG456Q. Either the remaining supply is used, or the board is revised around a current device.

What package is the XA3S400-4FGG456Q?

The XA3S400-4FGG456Q comes in the FGG456 package (456 pins).

Which versions of the XA3S400 come in industrial temperature?

The XA3S400-4FGG456Q is an automotive-temperature part, a wider range than industrial. 3 XA3S400 parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design. XA3S400-4FGG456I XA3S400-4FTG256I XA3S400-4PQG208I
