The AEC-Q100 grade is what separates this from a garden-variety CAN transceiver. If your design lives in a 0°C to 70°C office environment, you're paying for margin you don't need, but for anything that ships inside a vehicle or a factory panel, this is the right temperature bin.
The SN65HVD255DR is a pin-compatible CAN transceiver with a wider common-mode range and enhanced fault protection, including a bus-fault timeout and an active-low fault output. The SN65HVD251DR is the baseline version without these extra diagnostics. If your network runs in a clean environment with well-terminated cables, the SN65HVD251DR is sufficient. For systems that see intermittent bus shorts or ground shifts, the SN65HVD255DR adds a layer of resilience without changing the footprint.
