Replacement verdict
Compatible functional replacement candidate
The 5CEFA2U19A7N is a viable functional replacement candidate for the 5CEFA2F23C8N, sharing the same Cyclone V FPGA family, logic density, and core architecture. However, the differing package footprint and speed grade require careful validation before committing to a drop-in substitution in existing designs.

Frequently asked questions
What are the key differences between the 5CEFA2F23C8N and the 5CEFA2U19A7N?
The primary differences are package type, pin count, and speed grade. The 5CEFA2F23C8N uses a 484-pin FBGA package (F23) with a speed grade of 8, while the 5CEFA2U19A7N uses a 484-pin UBGA package (U19) with a speed grade of 7. Both are Intel (formerly Altera) Cyclone V FPGA devices with 25,000 logic elements and belong to the same 5CEFA2 device family.
Are the 5CEFA2F23C8N and 5CEFA2U19A7N functionally interchangeable?
No. Although both are Cyclone V 5CEFA2 devices with identical logic density, they differ in package construction (FBGA vs. UBGA), physical footprint, and speed grade. The 5CEFA2F23C8N is faster (speed grade 8) than the 5CEFA2U19A7N (speed grade 7). A direct drop-in replacement is not possible without verifying pinout, PCB land pattern, thermal characteristics, and timing closure against the respective datasheets.
Do the 5CEFA2F23C8N and 5CEFA2U19A7N have the same number of logic elements?
Yes. Both devices are part of the Cyclone V 5CEFA2 family and feature 25,000 logic elements (LEs). They also share the same adaptive logic module (ALM) count of approximately 9,430 ALMs, as documented in the Intel Cyclone V device overview.
What package types do the 5CEFA2F23C8N and 5CEFA2U19A7N use?
The 5CEFA2F23C8N uses a 484-pin FineLine BGA (FBGA) package, designated by the "F23" code. The 5CEFA2U19A7N uses a 484-pin Ultra FineLine BGA (UBGA) package, designated by the "U19" code. These packages have different ball pitches and physical dimensions, which affects PCB layout and assembly.
What do the speed grade suffixes C8 and A7 indicate on these devices?
The "C8" suffix on the 5CEFA2F23C8N indicates a commercial temperature grade with speed grade 8. The "A7" suffix on the 5CEFA2U19A7N indicates an automotive temperature grade with speed grade 7. Speed grade 8 is faster than speed grade 7, meaning the 5CEFA2F23C8N supports higher maximum operating frequencies for the same logic paths.
Can the 5CEFA2F23C8N be used as a substitute for the 5CEFA2U19A7N in an existing design?
Not directly. The 5CEFA2F23C8N is a commercial-grade FBGA device, while the 5CEFA2U19A7N is an automotive-grade UBGA device. Substitution requires verifying that the target application accepts a commercial temperature grade, that the PCB can accommodate the FBGA package footprint, and that timing margins are revalidated for the speed grade difference. Intel documentation should be consulted before any substitution.
Are both the 5CEFA2F23C8N and 5CEFA2U19A7N RoHS compliant?
Yes. Both devices are offered in lead-free, RoHS-compliant package options as stated in Intel's Cyclone V device documentation and distributor product pages. However, specific ordering codes and packaging variants should be confirmed with the manufacturer or authorized distributor for the exact compliance status of a given lot.
What configuration and transceiver resources do the 5CEFA2F23C8N and 5CEFA2U19A7N offer?
Both devices are Cyclone V 5CEFA2 FPGAs and offer the same core configuration memory and logic resources for their density. However, the 5CEFA2F23C8N and 5CEFA2U19A7N differ in available user I/O pins due to their different package types (FBGA vs. UBGA), and neither device in the 5CEFA2 family includes high-speed transceivers, as transceivers are reserved for other Cyclone V variants. Exact I/O counts must be verified from the respective device pinout files.
