The BC637 shares a datasheet with the BC639.
The BC639 seems to be exactly the same except for a slightly higher voltage rating, it is available.
So not a mystery that the BC637 would disappear.

but he uses a BC637 & BC640 pair. They have the BC640 at mouser but NOT the BC637. What should I use instead for the BC637?
Or do you know a reliable place to get real ones?
(Or is there another equivalent complimentary pair that would be ideal to use instead?)
