I would have thought so. The buttons do look familiar but the dimensions may be different. I'd check e-bay regularly for donor models. The actual fitment should'nt be a problem, i think it just requires the small circlips to be removed after the module is out. Is the model number DW-8800BJ-1 or maybe an 8800MM? I reckon a few models between 1996 and 1999 may have similar buttons.
Is this the version with the Morse code generator?
