1. Mouser's prices and availability suck. Their transistor prices look
good, but everything else there is usually much more than Digikey or
Questlink. They don't give any useful information on their parts on the
web or in their catalog. On the web, the part numbers you mentioned are
listed as 'Possible stock - call for availability'... the few times I did
actually call, I got lead times of 3-6 months.
2. Both of the 3906's are listed as having a manufacturers part number of
'243906'... same for the 3904s. The 610s are listed as being General
Semiconductor parts, their data sheets are at
http://www.gensemi.com/pdfs/2n3904.pdf
http://www.gensemi.com/pdfs/2n3906.pdf
The 625s are listed as Central Semiconductor parts... they do not put
information about their non-SMT parts on the web... you have to order a
catalog from www.centralsemi.com.
