Likely an old wives tale.  The majority of semiconductors used in 
simple circuitry like an alternator regulator are perfectly happy 
cooking right along at temps as high as 400 degrees or more without 
any problems.   Capacitors likely don't much care for temps over 300 
degrees if they're electrolytics but how often does anything in an 
engine bay get hot enough to flash-boil water unless something was on 
fire?    ;)   Besides, the caps in those regulators weren't usually 
electrolytics anyway.


Stick that internal reg alt in the 'Vair and head out.   No problems.
