Can I use this wirewound resistor as a substitute?
Because this is the only available component near my area.

It is wise to discuss the application to ensure inductance is not going to be a problem otherwise you need to order the Non-Inductive PN . If just a supply current limiter, then ok.
FYI
Non Inductive Resistor. To specify add N, e.g.: NHS50 56R J
Worth noting that the original is almost certainly an inductive type. If you use the metal cased one you found at RS, ensure you bolt it flat to the metal surface below it and ideally, use some heat sink compound to help with heat conduction .
It is worthwhile to note that non-inductive wire-wound inductors are bi-filar wound with current in opposite direction and look the same on the outside.
The application is that to make a new eddy current dynamometer from scratch. The use of the black wirewound resistor as a voltage limiter.
The NHS50 56R J will substitute the original (black) wirewound resistor in our new eddy current dynamometer.
