NEC table210.21(B)(3). ============ A 15 amp duplex receptacle can be wired to a 20 amp rated circuit.

Can you use a MDL for MDA fuse?

Depends on the voltage across the fuse. For fuses rated below 9 amps, the two types are almost identical (MDL has slightly lower AC Interrupting amperages), and both are rated for use up to 250V. For fuses rated above 9 amps, the MDL fuses are rated for use up to 32V, while the MDA fuses are rated for use up to 250V. More info on Cooper Bussmann (link below).
