The "YZZA2" filter is the YZZA5. The "2" is most likely the internal (not customer sourceable) identification number. I was actually going to make a YouTube video about this after seeing a video about fake Toyota parts.
This cross-labeling mismatching problem doesn't help those of us that like to be extra sure.
...all that being said: you have the correct filter.
Usually in manufacturing, all materials have a part number, down to the solder and wires.
YZZA5 is most likely the assembly (or kit) that includes the filter, o-ring kit, plastic drain funnel, cardboard box.
