English and Italian threads are close enough that they can be used interchangeably. They differ very slightly so going back and forth repeatedly isn't advisable but one change is fine.
The overwhelming majority of Sun Tour freewheels were English threaded so, unless your freewheel is VERY odd or your bike is an old French model you should be ok.
Later added info: Here is a quote from Sheldon Brown's web site about French freewheel threads.
"If your hub is made for a French-thread freewheel, a standard freewheel will fit on, but be very loose and will be unusable.
It is not possible to put a French freewheel on a standard hub without considerable violence."
So if the freewheel is French and the hub English or Italian, or vice-versa, the mis-fit will be obvious.
