Lifecycle reality — it's end-of-life
The FR-A740-00380-EC: Mitsubishi has flagged this drive as eol_hot, meaning the plug is being pulled. There's no official successor listed in our records, so once the last-time-buy window closes, the only way in is the surplus or broker channel. If you're filling a BOM line for an existing panel, move now or start qualifying a replacement frame.
