Lifecycle & Sourcing Reality
The FR-A720-7.5K: If your BOM specifies this exact order code, replacement is not straightforward — Mitsubishi's current A740 series (FR-A740-05470-NA, FR-A740-00570-NA, FR-A740-00040-NA) is a different platform, not a direct plug-in swap. Panel re-engineering, parameter transfer, and possibly bus re-termination are required.
