Yeah, the PX06 moniker and that JAN code are both for the fighter kit.
Funny thing is when I translate the page @Anasazi37 linked to into English (using the 'laguage' button on the bottom of the page) all the info about the fighter kit disappears, and it just shows the Rei Ayanami, the 2 Dougram kits, And the Asuka Langley product delays -- weird !
