5R4 MAY be OK, depending on circuit values. Peak current limit is lower for 5R4. Peak current depends on (1)transformer voltage (2) transformer winding resistance plus any other limiting resistance (3) load current (4) value of input capacitor. Voltage drop depends on load, and may not be that different, depending on current draw. Peak current is difficult to measure, but can be modeled using Duncan Amps' free PSU Designer program.
