As long as it is a 0 angle nozzle and a 6mm pressure section diameter you are good. The part numbers have the spray angle and the pressure section diameter encoded into it.

I'm using some 12 degree Citroen/Peugeot nozzles in the om603 right now and they seem to be performing admirably. Also tried some vw nozzles which seemed to smoke a lot more under load and some other ones I can't remember.
I tried to capture some high speed video pop testing various nozzles. This is played back at 1/10th speed.

DN0SD193 VW nozzle. This one made too much smoke in the OM603

12SD290. These are the nozzles I'm using now. Other than some white smoke after cold start they seem to work very well in the 603.
