Servo plugs are the same. The frequency shift just describes one part of the radio signal. The receiver must match the transmitter type. After that, gyros and servos should be universally compatible.
Some have a tab on the plug to force proper polarity. If the receiver has a slot for that tab, you know that you are plugging it in the proper direction. Servos with that tab can be plugged into receivers without the slots if you cut the tab off.
