TX2 (900-83310-0001-000) BS -> BV

I noticed in the nomenclature of 2 different TX2 modules that were purchased last year a difference in the 2 letters that appear after the part number (900-83310-0001-000)

One TX2 states BS, and another module states BV.
This appears to change the way our software interacts with the module.

What is the difference between the modules with BV and BS?

Alternate source has been used for some passive components. No change expected in module behavior. Could you provide further details as what change you are observing?

Thanks for the reply. I am waiting more details from our engineering team on the exact software issue, but our software is certainly not working with the same with the BV revision.
Can you clarify what alternate source was used for what components? This may help us.

We do not provide further details as the discrete passive components are functional equivalents and do not affect the module specifications/performance.
