Are regular DCC turnout and the #4 turnout interchangeable?

[whizamit]

I am curious to know if i can use the regular DCC turnout (with 18" radius) interchangeably with the #4 turnout.
If i had an oval of 18" curves, I am assuming i could replace one of the curves with a DCC turnout.
Can i do the same with a #4 turnout and would it still fit?

Thanks

The two turnouts are not interchangeable, and depending on your track plan, may be difficult to adapt using stock, unaltered E-Z track.
