The user must qualify these alternates independently against their application requirements.
- 6ES79720BB520XA0 shares identical specs with the seed; the title variant indicates a programming port (PG) angled configuration.
- 6ES79720BB120XA0 also mirrors seed specs but lists a different mechanical variant in its title.
- 6ES79720BA420XA0 uses the BA prefix (vs BB on seed) and titles suggest a variant without PG port.
- 6ES79720BA120XA0 carries the BA prefix and is RoHS non-compliant (critical distinction for new designs).
- 6ES79720BA520XA0 shares BA prefix with the last two alternates; angled variant without PG per title.
Engineering verification checklist
- Confirm connector gender (male pins) matches PROFIBUS device port
- Verify mechanical orientation (angled/90° vs straight) fits panel layout
- Check PG port requirement—some variants omit it
- Validate RoHS compliance status if applicable to end market
- Confirm stock availability for required quantity (seed: 3 total)
- Verify bulk packaging meets procurement quantity needs
