Industrial temperature range — the 'I7' suffix matters
The 'I7' suffix denotes the industrial temperature grade: -40°C to 100°C junction. This is the main differentiator from commercial-grade Cyclone IV E parts (0°C to 85°C). If your BOM calls for outdoor, under-hood, or unheated factory-floor operation, this is the grade you need. The commercial-grade sibling EP4CE40F29C8, for example, is limited to 0°C to 85°C and would not be a drop-in replacement for cold-start environments.
