Hi. My name is*****’m a camera repair technician with over 20 years in the business and I'll be glad to help you with your question today.
Unfortunately, it is not. This part is available only with a new main circuit board and would require re-programming by the factory.
The only real source for spare parts for this camera is EBay. Most repair shops keep a stock of salvaged cameras for parts such as this. You may want to check locally for a camera repair shop in your area, or, if you need assistance finding a shop, please let me know and I'll locate one for you.
