SN52723 Availability or Alternative Device

Hey Jared, 

This device can no longer be ordered. For obsolete or surplus TI product Rochester Electronics https://www.rocelec.com/ is a good resource, however it doesn't appear to be orderable here either. 

Thanks,

Hi Jared,

I looked into this further and I was able to locate the modern, active equivalents for this device.  So yes, they are still active and being sold.  From the datasheet you linked:

Modern part numbers:

SN52723 = LM723
https://www.ti.com/product/LM723
https://www.ti.com/product/LM723QML
https://www.ti.com/product/LM723C-MIL
https://www.ti.com/product/LM723JAN-SP

SN72723 = UA723
https://www.ti.com/product/UA723

Please reply if you have any further questions.

Thanks,

Stephen

Hey Jared,

I looked online and could only find the 1984 TI databook, which does not list those SN part numbers.  See pages 471 and 636 (6-169)  in this link:

https://usermanual.wiki/Document/1984TILinearCircuitsDataBook.571477835/view

The 1984 databook and the 1973 datasheet you provided sure do look the same.  The only real difference I can see is the comment on the first page:

1984 databook:
"Direct Replacement for Fairchild uA723M and uA723C"

1973 datasheet:
"Designed to be Interchangeable with Fairchild uA723 and uA723C Respectively"

I glanced at the different datasheets and electrically speaking, the LM723 appears to meet the same specifications as the SN52723, but I cannot guarantee that other differences remain. If the customer has purchased the LM723 they can see the list of PCN's associated with it, if any, over the years.  

Thanks,

Stephen
