They are all the same diameter, if that's what you're asking.
But they come in 2 pin mono, 3 pin mono, 3 pin stereo, and 4 pin stereo. But they will all work and do the same thing for a normal guitar needing just a mono output.
Outer diameter is 11.5-11.8mm (.453-.465"). The hole in the guitar is usually 12mm or 1/2" dia. so any barrel jack will work, import or American.
