Substitute Part Grouping Explanation

Substitution for the EP3C40F780C7 is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical number of logic elements (39,600) and LABs/CLBs (2,475)
• I/O Configuration: Matching I/O pin count (535 pins)
• Memory Capacity: Equivalent embedded RAM (1,161,216 bits)
• Electrical Specifications: Identical supply voltage range (1.15V ~ 1.25V)
• Package Specification: Same 780-BGA package footprint (29×29 mm)
• Thermal Range: Matching operating temperature (0°C ~ 85°C)
• Series Compatibility: Same Cyclone® III product family

The substitute part EP3C40F780C7N meets all these criteria and is therefore a direct functional equivalent. Differences exist only in compliance certifications and inventory sourcing.

Parameter Comparison

Engineering Selection Recommendations

Both EP3C40F780C7 and EP3C40F780C7N are functionally identical Cyclone® III FPGAs with no differences in electrical performance, logic capacity, or thermal characteristics. Selection between these parts should be based on compliance requirements:

• EP3C40F780C7: Select when RoHS non-compliant components are acceptable or when legacy design documentation specifies this exact part number.
• EP3C40F780C7N: Select for applications requiring RoHS compliance. This variant meets environmental and hazardous substance restrictions while maintaining identical functional specifications.

Both parts carry active product status and are suitable for new designs. The choice between them is driven by regulatory and procurement requirements rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Are EP3C40F780C7 and EP3C40F780C7N pin-compatible?

A: Yes. Both parts use the 780-BGA package with identical pin assignments, footprint dimensions (29×29 mm), and electrical characteristics. No PCB redesign is required when substituting between these parts.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. EP3C40F780C7N is RoHS compliant, while EP3C40F780C7 is not. All functional specifications, including logic elements, I/O count, RAM capacity, and operating parameters, are identical.

Q: Can I use EP3C40F780C7N as a direct replacement for EP3C40F780C7?

A: Yes. EP3C40F780C7N is a direct functional substitute. It provides identical logic capacity, I/O configuration, and electrical performance. The substitution is valid for all applications where the original part was specified.

Q: Are there any thermal or electrical differences between these parts?

A: No. Both parts operate within the same voltage range (1.15V ~ 1.25V) and temperature range (0°C ~ 85°C). Thermal behavior and power characteristics are equivalent.

Q: What does the "N" suffix in EP3C40F780C7N indicate?

A: The "N" suffix typically indicates a variant with different compliance certifications. In this case, it denotes RoHS compliance status while maintaining all other specifications identical to the base part number.

Q: Are both parts suitable for new designs?

A: Yes. Both EP3C40F780C7 and EP3C40F780C7N carry active product status and are appropriate for new designs. Selection should be based on your application's compliance requirements.
