Replacement verdict
Compatible functional replacement candidate
The 5CEFA5U19I7N and 5CEFA5U19C6N are functionally compatible Cyclone V FPGA devices sharing identical logic density, package, and I/O configuration, with the primary distinction being the industrial versus commercial temperature grade. The 5CEFA5U19C6N offers a faster speed grade, making it suitable for higher-performance commercial applications, while the 5CEFA5U19I7N provides extended temperature range support for industrial environments. Both devices are viable substitutes when the target application's thermal and timing requirements are properly matched.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA5U19I7N | 5CEFA5U19C6N | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -40°C to 100°C (Industrial) | 0°C to 85°C (Commercial) | Determines the environments in which the device can reliably operate; industrial-grade parts support harsher conditions than commercial-grade parts. |
| Speed Grade | 7 (faster) | 6 (slower) | Speed grade affects maximum operating frequency and timing closure; a faster grade can meet tighter timing requirements but may cost more. |
| Logic Elements (LEs) | 77,000 | 77,000 | Logic capacity determines the complexity of digital designs the FPGA can implement; identical LE counts mean equivalent logic resources. |
| Total Embedded Memory | 4,460 Kbit | 4,460 Kbit | On-chip memory is used for buffering, FIFOs, and data storage; matching memory ensures equivalent on-chip storage capability. |
| Embedded Multipliers (18x18) | 150 | 150 | Hard multipliers accelerate DSP operations such as filtering and FFTs; identical counts provide the same DSP throughput potential. |
| Package | UBGA-484 | UBGA-484 | Package type and pin count must match for board-level compatibility and footprint interchangeability. |
| Number of I/O Pins | 224 | 224 | I/O count determines how many external signals the FPGA can interface with; matching counts ensures equivalent connectivity. |
| Core Supply Voltage | 1.1 V | 1.1 V | Core voltage must match the board power design; identical values allow the same power delivery network to be used. |
| Manufacturer Part Status / Grade | Industrial grade | Commercial grade | Grade designation affects qualification, reliability screening, and suitability for automotive, industrial, or consumer applications. |

Frequently asked questions
What are the 5CEFA5U19I7N and 5CEFA5U19C6N devices?
Both are Intel (formerly Altera) Cyclone V FPGAs in the same 484-pin UBGA (U19) package with 5CEFA5 density and speed grade variants. The 5CEFA5U19I7N is the industrial temperature grade device, while the 5CEFA5U19C6N is the commercial temperature grade device.
What is the difference between the I7N and C6N suffixes?
The "I7" suffix indicates an industrial temperature grade device with a speed grade of 7, and the "C6" suffix indicates a commercial temperature grade device with a speed grade of 6. The "N" suffix in both part numbers indicates lead-free (Pb-free) packaging.
Are the 5CEFA5U19I7N and 5CEFA5U19C6N pin-compatible?
Yes. Both devices use the same 484-pin UBGA (U19) package and the same Cyclone V 5CEFA5 die, so the pinout and package footprint are identical. The difference is limited to temperature grade and speed grade.
Can the 5CEFA5U19C6N be used as a drop-in replacement for the 5CEFA5U19I7N?
Not unconditionally. The 5CEFA5U19C6N is rated for commercial temperature ranges and has a different speed grade than the 5CEFA5U19I7N. A replacement is only valid if the target design's operating temperature range and timing requirements are satisfied by the commercial-grade, speed grade 6 device.
What are the operating temperature ranges for these two devices?
The 5CEFA5U19I7N is specified for the industrial temperature range, while the 5CEFA5U19C6N is specified for the commercial temperature range. Exact junction and ambient temperature limits should be confirmed from the official Intel Cyclone V device datasheet.
Do both devices support the same configuration and transceiver features?
Yes. Since both are Cyclone V 5CEFA5 devices in the same U19 package, they share the same logic density, memory resources, DSP blocks, and transceiver capabilities. The differences are limited to speed grade and temperature grade.
Which device is preferred for industrial applications?
The 5CEFA5U19I7N is the appropriate choice for industrial applications because it is rated for the industrial temperature range. The 5CEFA5U19C6N is intended for commercial temperature environments.
Are both part numbers RoHS compliant?
Both part numbers carry the "N" suffix, which indicates lead-free (Pb-free) packaging. RoHS compliance should be verified against the specific Intel product ordering information and material declaration documentation.
