Hello,
Below a simple difference between them.
Mean time between failures – MTBF (hours)
C9300-24U 238,410
C9300-24UB 354,300

But there is other difference, they have small difference.

Hi there,

The B in the product name denotes Buffer. In particular deep buffers:

Deep buffer Technology

Cisco Catalyst 9300 higher scale models have a deeper buffer to address the requirements of rich multi-media lossless content delivery and large routing tables in a fixed access solution with a wide range of uplink choices for deployment flexibility.

cheers,

Seb,
