Features:
- The replacement identity combines HIEE450964R0001 and SA9923A-E.
- The A-E suffix and physical layout are part of the selection boundary.
- The page avoids an unsupported pulse-amplifier function claim.
Using both markings reduces ambiguity when sourcing boards from legacy inventories.
Revision, connector and rack comparison determines whether a candidate belongs in the installed system.
Conservative function wording prevents a purchasing decision based on an unverified adjacent-board description.
