Selection notes
What must be checked before accepting BCTD instead of BCWE?
Treat the changed suffix as a change to the requested operating bin. The guide distinguishes WE from TD, so retain BCWE in the RFQ and have engineering approve the offered device against the controller’s operating point before accepting a substitution.
Does a matching 78-ball count establish E-die compatibility?
Check the F-die outline, ball assignments and system qualification directly. The guide identifies WF as a separate revision from WE; a matching organization and package ball count alone does not establish that an E-die footprint or operating profile can be reused.
