Substitute Part Grouping Explanation

Substitution of the EP3C40F324C8 is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical number of logic elements (39,600) and LABs/CLBs (2,475)
• Memory Configuration: Identical total RAM bits (1,161,216)
• I/O Count: Identical number of I/O pins (195)
• Electrical Specifications: Identical supply voltage range (1.15V ~ 1.25V)
• Package Specification: Identical 324-BGA package and 324-FBGA (19x19) supplier device package
• Thermal Characteristics: Identical operating temperature range (0°C ~ 85°C TJ)
• Series Designation: Identical Cyclone® III series classification

The substitute part EP3C40F324C8N meets all these criteria and differs only in RoHS compliance status, making it functionally and mechanically interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both EP3C40F324C8 and EP3C40F324C8N are active production parts with identical functional and electrical specifications. Selection between these parts should be based on regulatory and compliance requirements:

• EP3C40F324C8: Select this part number when RoHS non-compliant components are acceptable or required by design specifications.
• EP3C40F324C8N: Select this part number when RoHS compliance is mandated by end-product regulations, customer requirements, or supply chain policies. This variant maintains full functional equivalence while meeting environmental compliance standards.

Both parts carry REACH Unaffected status and are suitable for the same circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Are EP3C40F324C8 and EP3C40F324C8N pin-compatible?
