LM139: Replacement for /883B

Part Number: LM139

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?
