Does any brand 2 pole 15 amp circuit breaker fit a Square D or Cutler
Hammer circuit breaker panel box (each about 6 years old)?

If you mean are all circuit breakers interchangeable, the answer is
"no", even all amongst the same vendor.

If you mean are there at least some non-OEM-manufactured breakers to fit
at least some panels, the answer is "yes".

The panel will list the series of breaker(s) approved for it; look for
one that is on that list.
