Replacement verdict
Compatible functional replacement candidate
The 5CEBA2F17C8N and 5CEBA2U15I7N are both Cyclone V FPGA devices from Intel (Altera) sharing the same logic density and core architecture, making them functionally related candidates. However, they differ in package type, operating temperature grade, and speed grade, so the 5CEBA2U15I7N is not a direct drop-in replacement for the 5CEBA2F17C8N. Designers must validate pinout, thermal requirements, and timing closure before substituting one for the other in an existing design.

Frequently asked questions
What are the 5CEBA2F17C8N and 5CEBA2U15I7N devices?
Both are Intel (formerly Altera) Cyclone V FPGA devices. The 5CEBA2F17C8N is a Cyclone V E FPGA in a 256-pin FBGA package (17 mm x 17 mm) with commercial temperature grade C8 speed grade. The 5CEBA2U15I7N is a Cyclone V E FPGA in a 324-pin UBGA package (15 mm x 15 mm) with industrial temperature grade I7 speed grade.
Do the 5CEBA2F17C8N and 5CEBA2U15I7N have the same logic density?
Yes. Both devices are members of the Cyclone V E A2 density tier, which provides approximately 25,000 logic elements (LEs), 9,430 adaptive logic modules (ALMs), and 1,880 Kbits of embedded memory. The primary differences between the two part numbers are package type, pin count, temperature grade, and speed grade.
Can the 5CEBA2F17C8N and 5CEBA2U15I7N be used interchangeably in the same PCB design?
No. The 5CEBA2F17C8N uses a 256-pin FBGA package with a 17 mm x 17 mm body, while the 5CEBA2U15I7N uses a 324-pin UBGA package with a 15 mm x 15 mm body. The different pin counts, ball maps, and PCB land patterns make them physically and electrically incompatible for direct drop-in replacement without a redesign.
What is the difference in temperature grade between the 5CEBA2F17C8N and 5CEBA2U15I7N?
The 5CEBA2F17C8N has a commercial temperature grade (C8), typically specified for 0°C to 85°C junction temperature operation. The 5CEBA2U15I7N has an industrial temperature grade (I7), typically specified for -40°C to 100°C junction temperature operation. The industrial-grade device is suitable for harsher environments.
What is the difference in speed grade between the 5CEBA2F17C8N and 5CEBA2U15I7N?
The 5CEBA2F17C8N is a C8 speed grade device, while the 5CEBA2U15I7N is an I7 speed grade device. In Intel FPGA nomenclature, lower numbers indicate faster speed grades. Therefore, the I7 speed grade is faster than the C8 speed grade, offering higher maximum operating frequencies and tighter timing performance.
Which device offers more user I/O pins, the 5CEBA2F17C8N or the 5CEBA2U15I7N?
The 5CEBA2U15I7N offers more user I/O pins due to its larger 324-pin UBGA package compared to the 256-pin FBGA package of the 5CEBA2F17C8N. Designers requiring higher I/O count should verify the exact available user I/O in the respective device pin-out files from Intel documentation.
Are the 5CEBA2F17C8N and 5CEBA2U15I7N both RoHS compliant?
Yes. Both the 5CEBA2F17C8N and 5CEBA2U15I7N are offered in RoHS-compliant packages as standard Intel Cyclone V FPGA products. The "N" suffix in both part numbers indicates lead-free (Pb-free) packaging, which is consistent with RoHS requirements.
Which device is more suitable for industrial applications, the 5CEBA2F17C8N or the 5CEBA2U15I7N?
The 5CEBA2U15I7N is more suitable for industrial applications because it carries an industrial temperature grade (I7), supporting operation from -40°C to 100°C junction temperature. The 5CEBA2F17C8N is rated for commercial temperature ranges (0°C to 85°C) and is better suited for consumer or office-grade environments.
