Real Time Clock

Hello, we were using RTC M41T81SM6E (ST) (Soic8)
That does not see to be available any where. Does anybody have an idea of an alternative.

Hello DavidJohn,

It seems PN: M41T81SM6E is obsolete, so it will be difficult to find.
However, I do see PN: 497-4709-1-ND which looks to be a very good substitute.
Here is a side-by-side if you would like to compare.
