Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C8N and 5CEFA7U19C6N are both Intel (Altera) Cyclone V FPGAs sharing the same core architecture, logic cell family, and 28 nm process technology, making them functionally related candidates. However, they differ in logic density, package type, pin count, and speed grade, so the 5CEFA7U19C6N cannot be treated as a direct drop-in replacement for the 5CEFA2F23C8N without a full design review covering resource utilization, PCB footprint, and timing closure.

Frequently asked questions
What are the key differences between the 5CEFA2F23C8N and the 5CEFA7U19C6N?
The 5CEFA2F23C8N is a Cyclone V E FPGA with 25,000 logic elements in a 484-pin FBGA package, while the 5CEFA7U19C6N is a Cyclone V E FPGA with 149,500 logic elements in a 484-pin UBGA package. They differ in logic density, package type, and speed grade.
Are the 5CEFA2F23C8N and 5CEFA7U19C6N pin-to-pin compatible?
No. The 5CEFA2F23C8N uses a 484-pin FBGA package, and the 5CEFA7U19C6N uses a 484-pin UBGA package. These are different package types with different ball maps and PCB land patterns, so they are not pin-to-pin compatible.
Can the 5CEFA2F23C8N be used as a direct replacement for the 5CEFA7U19C6N?
No. The two devices have different logic densities, package types, and speed grades. A direct replacement is not possible without redesigning the PCB and revalidating the logic design against the target device's resources and timing.
What is the logic element count for each device?
The 5CEFA2F23C8N contains 25,000 logic elements. The 5CEFA7U19C6N contains 149,500 logic elements.
What speed grade does each device use?
The 5CEFA2F23C8N is specified with speed grade C8. The 5CEFA7U19C6N is specified with speed grade C6. The C6 speed grade is faster than C8 in the Cyclone V family.
Do both devices belong to the same FPGA family?
Yes. Both the 5CEFA2F23C8N and the 5CEFA7U19C6N are members of the Intel (formerly Altera) Cyclone V E FPGA family.
What package types are used by these two devices?
The 5CEFA2F23C8N uses a 484-pin FineLine BGA (FBGA) package. The 5CEFA7U19C6N uses a 484-pin Ultra FineLine BGA (UBGA) package.
Which device offers higher logic capacity for larger designs?
The 5CEFA7U19C6N offers higher logic capacity with 149,500 logic elements, compared to 25,000 logic elements in the 5CEFA2F23C8N. The 5CEFA7U19C6N is better suited for larger, more complex designs.
