   You say 0.5F, which is 0.5 Farad, which would be a very large cap.   
   What amount of capacitance do you really have? Is it 0.5uF, or 0.5   
   nF???????????   
      
   Polypropylene or Polyester will be fine as a replacement as long as   
   the capacitance value is the same and the voltage rating is the same,   
   but only if the original cap's capacitance and V ratings were correct.
