The only substitute that I found for the Littelfuse was the Cooper Bussman equivalent. Those are two of the big players in the specialized fuse market.

Since it is a 20 amp fuse it may be the strongest link in your system. Is this on a 20 amp 120 volt circuit? Does the power supply have a NEMA 5-15 plug or a 5-20 plug? It seems to me that since this is a time delay fuse the circuit breaker may be just as important. After breakers get old the thermo-magnetic properties can deteriorate and cause fatigue. I don't know if this is audible.

Is the line from the breaker box 10 gauge or 12? (assuming 120 volt) I found that there was a definite improvement using dedicated ten gauge lines. (My theory is that there is less voltage drop as current increases.)

Since you have a nice power supply you could try experimenting with different power cords. I think that a standard 15 amp locking female connector with a 15/20 amp straight plug adapter may work to convert the locking function to straight. This would make trying out other power cables easier.
