TI and DSCC seem to have a number of variations for obtaining a LM139J with MIL-STD-883 screening.
My company has legacy BOMs with part number LM139J/883B. That's an old school part number. I'm trying to determine best replacement, with continuing support for device, from the available variations
Seems 883B is replaced by LM139J/883 (which drops the Rev. B from 883B) . Or by DSCC 7700801CA. Or even LM139JB (that I not sure of). What would be the better choice to ensure I have MIL-STD-883, at best cost, and greatest chance of continuing product production?
