Digikey does not carry them, nor do any of the major parts distributors. The type that are used in pinball with the plastic ramps on both sides are special order based on what Ed at Great Plains told me. He orders them factory direct and they have a long lead time.
In a pinch, you can combine a few of smaller size to build up to the number of pins you need. I have a LOT of 2-pin 0.156" pitch laying around, and I will use 3 or 4 of them for prototyping when I'm running low on larger ones. I need to buy a couple hundred myself now, and I'm patiently awaiting GPE getting them.
If you only need one or two, you can sometimes find them at other Pinball resellers for a higher price than GPE. I can't afford the price difference in the quantity I buy.
