Automotive grade means the temperature range and qualification
That puts it in the right bin for under-hood electronics, engine bay modules, and cabin-domain controllers where the board sees heat soak and cold cranks. The industrial-temperature sibling S25FL128LAGNFI010 tops out at 85°C and lacks the AEC-Q100 stamp — if your BOM calls for automotive-grade silicon, this is the one to lock in.
The FL-L series remains a current product line from Infineon, with no announced end-of-life. Sourcing through independent distribution is straightforward — we procure against an RFQ and confirm availability and pricing at quote time.
