Alternative for a M48Z128Y-120

In a SONY CRT G70 there is a NOVSRAM M48Z128Y-120.
It appears this Dallas chip is no longer available.
In an AVS Forum there is a thread dedicated to replacing the Dallas chip in the G90 (the model after the G70), and there is a side discussion where one user has posted that DALLAS/MAXIM DS1245Y-120+ is a suitable alternative to the M48Z128Y-120. This is what I would like to confirm.

Hello MJH,
Welcome to the DigiKey TechForum.
I was able to find the datasheet for the M48Z128Y-120, linked HERE.
It does appear to confirm that DS1245Y-120±ND would work as a suitable alternative for the obsolete part.

thanks Nick
