Unless it is a critical inductance application like a 
parasitic suppressor or a critical applications like a short 
duty transient energy absorbing resistor, a regular metal 
film or carbon film or metal oxide would work perfectly. 
They are all better than old carbon comps, except for 
inductance critical or surge critical applications.

If it is a surge or inductance critical application like a 
HV fault resistance, parasitic suppression, or RF 
termination; a metal composition like a OX or OY series 
Ohmite would be a superior replacement.
