Replacement verdict
Compatible functional replacement candidate
The 5CEFA4F23I7N and 5CEFA2U19C6N are both Intel Cyclone V FPGAs sharing the same core architecture and logic cell technology, making them functionally related candidates. However, they differ significantly in logic density, package footprint, and operating temperature grade, so a direct drop-in replacement is not possible without design and PCB revisions. The 5CEFA4F23I7N offers higher logic capacity and industrial temperature support, while the 5CEFA2U19C6N provides a smaller footprint with commercial temperature rating. Validation of resource utilization, pinout compatibility, and thermal requirements is strongly recommended before substitution.

Frequently asked questions
What are the key differences between the 5CEFA4F23I7N and the 5CEFA2U19C6N?
The 5CEFA4F23I7N is a Cyclone V FPGA with 49,000 logic elements (LEs) in a 484-pin FBGA package, rated for industrial temperature range (I7). The 5CEFA2U19C6N is a Cyclone V FPGA with 25,000 LEs in a 484-pin UBGA package, rated for commercial temperature range (C6). The 5CEFA4F23I7N offers higher logic density and industrial temperature support, while the 5CEFA2U19C6N provides lower logic density in a smaller UBGA package with commercial temperature rating.
Are the 5CEFA4F23I7N and 5CEFA2U19C6N pin-to-pin compatible?
No. The 5CEFA4F23I7N uses a 484-pin FBGA package (F23), while the 5CEFA2U19C6N uses a 484-pin UBGA package (U19). Although both have 484 pins, the package types and ball maps differ, so they are not pin-to-pin compatible. PCB land patterns and signal assignments must be verified against the respective device pinout documents.
Can the 5CEFA2U19C6N be used as a direct substitute for the 5CEFA4F23I7N?
No. The two devices differ in logic density (25,000 LEs vs. 49,000 LEs), package type (UBGA vs. FBGA), and temperature grade (commercial vs. industrial). A direct substitution is not possible without redesigning the PCB and verifying that the lower logic density and commercial temperature range meet the application requirements.
What are the operating temperature ranges for these two devices?
The 5CEFA4F23I7N is rated for the industrial temperature range, typically -40°C to +100°C junction temperature (I7 speed grade). The 5CEFA2U19C6N is rated for the commercial temperature range, typically 0°C to +85°C junction temperature (C6 speed grade). The industrial-grade device is suitable for harsher environments, while the commercial-grade device is intended for controlled environments.
Do both devices belong to the same FPGA family?
Yes. Both the 5CEFA4F23I7N and the 5CEFA2U19C6N are members of the Intel (formerly Altera) Cyclone V FPGA family. They share the same architecture, IP support, and development tools, but differ in logic density, package, and temperature grade.
What logic density does each device offer?
The 5CEFA4F23I7N provides 49,000 logic elements (LEs). The 5CEFA2U19C6N provides 25,000 logic elements (LEs). The higher LE count of the 5CEFA4F23I7N allows for more complex logic implementations, while the 5CEFA2U19C6N is suited for lower-density applications.
Which device is more suitable for industrial applications?
The 5CEFA4F23I7N is more suitable for industrial applications because it is rated for the industrial temperature range (-40°C to +100°C junction temperature) and offers higher logic density. The 5CEFA2U19C6N, with its commercial temperature range (0°C to +85°C junction temperature), is better suited for consumer or office-grade environments.
Are the speed grades of these two devices different?
Yes. The 5CEFA4F23I7N has a speed grade of 7 (I7), while the 5CEFA2U19C6N has a speed grade of 6 (C6). In the Cyclone V family, a lower speed grade number generally indicates a faster device. Therefore, the 5CEFA2U19C6N (speed grade 6) is faster than the 5CEFA4F23I7N (speed grade 7), but the 5CEFA4F23I7N offers higher logic density and industrial temperature support.
