Replacement verdict
Compatible functional replacement candidate
The 10M50DAF256I7G and 10M50DCF256C7G are functionally compatible as both are Intel MAX 10 FPGA devices with identical 50,000 logic elements and 256-pin FBGA packaging. However, the 10M50DAF256I7G is rated for industrial temperature operation while the 10M50DCF256C7G is rated for commercial temperature operation, making the industrial-grade variant the more robust choice for demanding environments. Designers should verify that the commercial temperature range of the 10M50DCF256C7G meets their system requirements before substituting it for the industrial-grade device.

Frequently asked questions
What are the key differences between the 10M50DAF256I7G and the 10M50DCF256C7G?
The primary differences are the operating temperature grade and the speed grade. The 10M50DAF256I7G is specified for the industrial temperature range and has a speed grade of 7, while the 10M50DCF256C7G is specified for the commercial temperature range and also has a speed grade of 7. Both devices are Intel MAX 10 FPGA products in the same 256-pin FineLine BGA package with 50,000 logic elements.
Are the 10M50DAF256I7G and 10M50DCF256C7G pin-compatible?
Yes. Both devices are offered in the same 256-pin FineLine BGA (FBGA) package and belong to the same Intel MAX 10 10M50 device family, so they share the same pinout and package footprint. However, any substitution must still be validated against the specific design requirements and manufacturer documentation.
What is the difference in operating temperature range between these two devices?
The 10M50DAF256I7G is rated for the industrial temperature range, while the 10M50DCF256C7G is rated for the commercial temperature range. The industrial-grade device is intended for applications requiring operation over a wider temperature span, whereas the commercial-grade device is intended for standard commercial environments.
Do both devices have the same logic density and package?
Yes. Both the 10M50DAF256I7G and the 10M50DCF256C7G are Intel MAX 10 10M50 devices with 50,000 logic elements (LEs) and are housed in a 256-pin FineLine BGA package. The differences between them are limited to the temperature grade and the corresponding ordering code, not the logic density or package type.
Can the 10M50DCF256C7G be used as a drop-in replacement for the 10M50DAF256I7G?
Not necessarily. Although both devices share the same package and logic density, the 10M50DAF256I7G is an industrial-temperature-grade device while the 10M50DCF256C7G is a commercial-temperature-grade device. A drop-in replacement is only acceptable if the target application's operating temperature range is within the commercial grade limits and all other design parameters are verified against the manufacturer's datasheet.
What speed grade do the 10M50DAF256I7G and 10M50DCF256C7G use?
Both the 10M50DAF256I7G and the 10M50DCF256C7G use speed grade 7, as indicated by the "7" in their ordering codes. The speed grade is the same for both devices; the distinguishing characters are the temperature grade indicator ("I" for industrial in the 10M50DAF256I7G and "C" for commercial in the 10M50DCF256C7G).
Are these devices part of the Intel MAX 10 FPGA family?
Yes. Both the 10M50DAF256I7G and the 10M50DCF256C7G are Intel MAX 10 field-programmable gate array (FPGA) devices. The MAX 10 family features non-volatile instant-on configuration, integrated analog-to-digital converters, and other embedded capabilities, and both devices belong to the 10M50 density variant with 50,000 logic elements.
Which device should be selected for an industrial-temperature application?
The 10M50DAF256I7G should be selected for industrial-temperature applications because it is the industrial-grade variant. The 10M50DCF256C7G is the commercial-grade variant and is intended for commercial temperature environments. Final selection must be confirmed against the manufacturer's datasheet and the specific operating conditions of the design.
