The dongle is the core of the control area.DVDs are the same.
X1 = Japan, for example (tekken 4) TEF1 = Japan, (Soul Calibur II) SC21 = Japan
X2 = Export, for example (tekken 4) TEF2 = Export, (Soul Calibur II) SC22 = Export
X3 = United States, for example (tekken 4) TEF3 = United States, (Soul Calibur II) SC23 = United States
X4 = Mainland China, for example (Taiko Drum Master 11) T111004 = Mainland China/Simplified Chinese
X5 = Taiwan, Hong Kong, for example (Taiko Drum Master 11) T111005 = Taiwan/Traditional Chinese
So,
TED1=Japan
TED2=Export
TED3=United States
You should understand it this way, although this is also called Tekken, they are no longer the same game, your dongle can only be used with Tekken 5.1 and Tekken 5.0, but cannot match Tekken 5 Dark Resurgence because it is the ultimate version of Tekken 5 of the same era.
