The chances of that are very low.  This isn't an especially popular part, compared to the other things you find in TO-92 packages.  I think you'd have to wade through seas of transistors, lakes of regulators, rivers of references, and even ponds of thermosensors before you find a TLE2426 droplet.
 
To answer your question, though, yes, that second line is what you'd need to be looking for.  The last letter can be different for different temperature grades of the same part.

Where are you ordering from that you can't find a source? They're on Mouser for a buck seventy.
