Whoops! I think you caught one. It should be this:
660-MF1/4CC2490F
Not sure what happened there. Good catch.
Now I'm remembering...we were concerned about the .6 watt rating and the
original part that we ordered really didn't fit the pcb.
Then Andy determined 1/4 watt worked fine.
If you wanted you could try the 1/2 watt:
660-MF1/2DC2490F
Anyway, yes, you were right. I've updated the file online.
