When will the FA type breaker be obsolete, and what replaces it?

Product Line:

In June 2017, obsolescence for all remaining legacy F-frame circuit breakers and switches was announced.
In June 2019 all legacy F-frame circuit breakers and switches will be obsolete and unavailable for sale.  Affected products include any circuit breaker or switch with the prefixes FA/FH/FG/FJ/FK/FY.
Note that the FA Mag-Gard motor circuit protectors are already obsolete.

The F frame is being replaced by the Powerpact B frame and Powerpact H frame.  Dimensions for all of these frames are different and none are direct replacements for others, except in I-Line panels and swbds.
Dimension pages from catalogs are attached.
