What is the difference between LM139AJ/PB and LM139J/PB? Is it only that the A version has a smaller offset voltage?

Can these parts replace M38510/11201BCA?

Hello JDJ,

Yes. The LM139AJ and LM139J differ in the offset voltage specifications. These are ex-National Semiconductor devices and are considered commercial extended temp devices (not MIL 883). The /PB was Nationals way to define the lead plating (PB solder dip).

The M38510/11201BCA is a native TI MIL- 883 grade device, similar to LM139JB (also native TI).

Aside from minor differences due to different fab and designs from different companies (at the time), they should all function similarly in the majority of the applications (when not pushed outside datasheet specs).

So as long as you can replace a MIL device with a commercial device, they can replace the M38510/11201BCA.
