It is strange, the JAN and JANTX 2N#### series are regulated by JEDEC you might be able to compile some of what you want from the hundreds or more of "/" sheets. There is a similar body for Japanese 2SX#### (JIS) series with the same problem. from this i expect that there is a similar body for the BXX#### series parts with similar constraints. Moreover read the specifications carefully, there is no real general guarantee of interchangeability in 2NXXXX, 2SXXXX or BXX### series parts.
