The only real difference ---apart from the obvious which doesn't really matter in this comparison is that the 2SA1695 is Lo-Sat .

In my old book both are from the Sanken Electric Company (Allergo Microsystems ) --still in business it seems .

Thank you for reply. I have already soldered 1695 and they have shorter legs than 1694. So going to order 1694 to get right look.
