Not sure about the diode.  Depending on how it's used, you may be able to 
replace it with a generic component (1N4148 or something).  It seems to be a 
fairly obscure part (assuming the part number is correct), cross-references 
aren't turning up anything useful, but I don't think it's anything 
particularly special.
