It's 0603 (1608 Metric) size.
0.22R isn't written correctly as the R is used sometimes instead of the decimal, so that means 0.22. which isn't a value. You just want to use the decimal or the R, so 0.22 or R22 mean the same thing, and yes that value would be fine. You could really put anything 1ohm or less there and it would still work. Can even jumper it straight thru for a test if you like before getting any parts.
