It's actually "O", not "0" (zero). The "O" indicates the use of high temperature wax for potting the block. Otherwise, 3903-DG and 3903-ODG are the same part, using the same .01 uF capacitors inside.
On the blocks themselves, they may be embossed "3903-ODG" or stamped "3903ODG". Again, same part.
Incidentally, these bakelite blocks which have terminals connected across the incoming AC line should always be restuffed with X1/Y2 safety capacitors.
