I found a thread by Werk which references a different type of part ? link shown below :-
433Mhz Wireless Transmitter ASK DC 3-12V Perfect for Arduino/ARM/AVR | eBay
Is either fine or do i need an exact replacement for what I have ?
The one you found will work, and it have the same pinout.

You are right, the KXD10036 module somehow disappeared completely...
But the one you found on eBay has a power of "only" 15 dBm, I recommend using the H34C 433 MHz module. It should have a power of more than 25 dBm.
(Better range.)

Indeed the H34C 433 MHz module is more powerful ans stable, and it will work too, but be aware that it doesn't have the same pinout, so it isn't a direct replacement.

This suggestion from Hornichz makes all the sense for me. If I was you, before trying to replace the TX module I would try to replace the MOSFET T1 2N7000.
Ok thanks heaps for the suggestions - i will give them a try.
