Substitute Part Grouping Explanation

Substitution of the EP3C40F780C8 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: Identical I/O count (535 pins)
• Memory Capacity: Identical embedded RAM (1,161,216 bits)
• Package Geometry: Identical 780-BGA footprint and 780-FBGA (29x29) physical dimensions
• Electrical Specifications: Identical supply voltage range (1.15V ~ 1.25V) and operating temperature range (0°C ~ 85°C)
• Mounting Technology: Surface mount compatibility

The substitute part EP3C40F780C8N meets all these criteria and differs only in packaging format (Tray vs. standard packaging) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both EP3C40F780C8 and EP3C40F780C8N are functionally equivalent at the silicon level and are suitable for direct substitution in circuit designs. Selection between these parts should be based on the following criteria:

EP3C40F780C8: Select this part when RoHS non-compliant components are acceptable for the application and when standard packaging is preferred.

EP3C40F780C8N: Select this part when RoHS compliance is required by design specifications, regulatory requirements, or end-market standards. This variant is supplied in Tray packaging, which may be preferred for automated assembly processes. The ECCN classification difference (3A991D vs. 3A001A7A) may affect export compliance requirements depending on destination country.

Both parts maintain identical electrical performance, logic capacity, and thermal characteristics. The choice between them is driven by compliance requirements and packaging logistics rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can EP3C40F780C8N be used as a direct replacement for EP3C40F780C8 in existing designs?

A: Yes. Both parts are functionally identical in logic elements, I/O count, memory capacity, and electrical specifications. The substitution is valid at the circuit design level. Verify that your supply chain and compliance documentation can accommodate the RoHS status and ECCN differences.

Q: What is the difference between the packaging formats?

A: EP3C40F780C8 uses standard packaging, while EP3C40F780C8N is supplied in Tray format. Both use the same 780-FBGA (29x29) physical footprint and are surface-mount compatible. Tray packaging is typically used for high-volume automated assembly operations.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical functional characteristics. Select based on your application's regulatory and compliance requirements.

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

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

Q: What does the ECCN classification difference mean?

A: ECCN (Export Control Classification Number) affects export licensing requirements. EP3C40F780C8N carries ECCN 3A991D while EP3C40F780C8 carries 3A001A7A. Verify export compliance requirements with your legal or procurement department if international shipment is planned.

Q: Can I mix these parts in the same production batch?

A: Yes, from a functional standpoint. However, verify that your quality assurance, traceability, and compliance documentation systems can accommodate parts with different RoHS and ECCN classifications in the same batch.
