It is. I can guarantee it. I replaced the one in my 91 with a bulb out of my old 94 soft button EATC.

Finally am back in the shop with time to play around and, yes the shorter hardbutton lamps will work fine in the 92 clock. I have a couple pics on my phone comparing them. Will post if anyone is interested...
The bulbs that I took out of a 94 EATC were the exact same as the bulbs in my 92 clock.
There was tomfoolery going around that the clocks took the short bulbs lately. Now there is no question.
