Hello Folks,
I am in the process of replacing some components in an ancient Video Game Console (the mattel Intellivision). Originalyl it had a UA7805UC3 voltage regulator, I did not find any reference to that particular voltage regulator, but I tend to believe that it is interchangeable with the the L7805CV; but I may be wrong. Would anyone know if it is interchangeable or not? Thanks for any input.

Yes, if they have the same package they should be interchangeable.

 

Here is a link to TI's uA7805 page:
http://www.ti.com/product/ua7805
The datasheet for the uA78xx series is downloadable from that page.

The suffixes are different for various packages and miscellaneous configuration details. There has been a considerable re-vamping of part number suffixes over the last few years due to RoHS concerns (lead-free, etc)

The 78xx series of regulators are commodity parts, which means lots of different manufacturers make them, with different prefixes and suffixes - but the base numbers (7805, 7809, etc) are the same, and the pinouts are the same for a given package, and the specifications are all very similar.
