It's a TO-202 package. A 7810 isn't directly 
compatible. AIR, the pinout is reversed, and a 
7810 should have additional capacitance for 
stability (depending of the specific part, it may 
even be required). Also, on at least some of the 
clusters, the tab is used for ground, so you need 
to accommodate that (if you mount a 7810 upside 
down to fix the pinout, then the tab isn't against the foil).
