ROHS3 compliance is confirmed. For a production BOM, this part presents no imminent obsolescence risk; the supply channel is stable through standard distribution and independent sourcing.
This 256 Mbit density with Quad I/O at 133 MHz is a common choice for code storage in industrial controllers, networking gear, and FPGA configuration memories. If your design requires operation up to 105°C, the S25FL256SAGMFV000 (same density and speed, 105°C rated, Tray package) or the S25FL256SDSMFV013 (80 MHz, 105°C, Tape & Reel) are the temperature-upgraded alternatives within the same FL-S family. The S25FL256SAGBHI300 is a Tray-packaged sibling with otherwise identical ratings — the only difference is the shipping medium, not the silicon.
