DIP stands for "Dual In-line Pack", the form of most through hole integrated circuits.
2 pins "Dual In-line" is a bit impossible so you won't find them.
If you want a two pin socket, find a larger socket with pins which suit your application and cut off two pins with a sharp knife.
I do that sort of thing all the time.
The "2 pin oscillator" you refer to, I think you mean a quartz crystal.
An oscillator can be made using a crystal as its frequency determining element, but a crystal on its own is not an oscillator.
