EP3C40F484C8 Equivalent & Substitute Parts

Part Overview

The EP3C40F484C8 is a Cyclone® III Field Programmable Gate Array (FPGA) from Intel, featuring 39,600 logic elements, 331 I/O pins, and 1,161,216 bits of embedded RAM. This device is housed in a 484-BGA package and operates at 1.15V to 1.25V supply voltage across a 0°C to 85°C temperature range. The part is currently active in production and available in tray packaging. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable or when procurement requires alternative sourcing options that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the EP3C40F484C8 are determined by strict equivalence across the following critical parameters:

• Identical logic element count (39,600)
• Identical I/O pin count (331)
• Identical embedded RAM capacity (1,161,216 bits)
• Identical package type and footprint (484-BGA, 23x23mm)
• Identical supply voltage range (1.15V ~ 1.25V)
• Identical operating temperature range (0°C ~ 85°C)
• Same manufacturer (Intel) and series (Cyclone® III)
• Same mounting technology (Surface Mount)

The EP3C40F484C8N meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts relates to compliance certifications rather than functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the EP3C40F484C8 and EP3C40F484C8N are functionally and electrically identical Cyclone® III FPGAs with active product status. The EP3C40F484C8N is the preferred selection for applications requiring RoHS compliance, as it meets RoHS standards while the EP3C40F484C8 does not. Both parts maintain REACH Unaffected status and identical export control classifications (ECCN 3A991D). Selection between these parts should be based on regulatory and compliance requirements specific to the end application and target market. No functional performance differences exist between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can EP3C40F484C8N be used as a direct replacement for EP3C40F484C8?

A: Yes. Both parts are electrically and functionally identical with matching logic element counts, I/O configurations, RAM capacity, package type, voltage specifications, and temperature ratings. The primary difference is RoHS compliance status.

Q: What is the significance of the "N" suffix in EP3C40F484C8N?

A: The "N" suffix indicates RoHS compliance. The EP3C40F484C8N meets RoHS standards, while the EP3C40F484C8 does not. All other specifications remain identical.

Q: Are the package footprints identical between these parts?

A: Yes. Both parts use the 484-BGA package with 23x23mm dimensions. PCB layout and assembly requirements are identical.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts have identical Moisture Sensitivity Level (MSL) ratings of 3 with a 168-hour floor life.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, use EP3C40F484C8N. For applications without RoHS requirements, either part is suitable based on availability and procurement considerations.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical performance across all electrical and functional parameters.
