Industrial temperature range and package
The -40°C to 100°C junction temperature rating is the industrial (I) grade.
Sourcing and lifecycle reality

The -40°C to 100°C junction temperature rating is the industrial (I) grade.
Intel continues to manufacture the Cyclone IV E family.
The I7N suffix indicates industrial temperature grade (-40°C to 100°C junction), while the C8N suffix is commercial grade (0°C to 85°C). Both share the same logic density, I/O count, package, and supply voltage — the I7N is the drop-in extended-temperature version.
The closest functional equivalent is the Intel Cyclone 10 LP 10CL010YE144I7G — same 10320 logic elements, same 423936 RAM bits, same 144-EQFP package, and a similar 1.2V core supply. It is a validated second-source candidate for BOM resilience.
