Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EP3C5U256C6 is determined by strict equivalence across the following parameters:

• Identical logic element count (5136)
• Identical RAM capacity (423936 bits)
• Identical I/O pin count (182)
• Identical supply voltage range (1.15V ~ 1.25V)
• Identical operating temperature range (0°C ~ 85°C)
• Identical package specification (256-LFBGA, 14x14)
• Identical base product number (EP3C5)
• Same manufacturer (Intel)
• Same series (Cyclone® III)

The EP3C5U256C6N meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both EP3C5U256C6 and EP3C5U256C6N are active products with identical electrical and mechanical specifications. Selection between these parts should be based on compliance and regulatory requirements:

The EP3C5U256C6N is RoHS Compliant with ECCN 3A991D classification, making it suitable for applications subject to RoHS directives and export control compliance. The EP3C5U256C6 is RoHS non-compliant with ECCN EAR99 classification and should be selected only when RoHS compliance is not a requirement.

Both parts carry identical HTSUS code 8542.39.0001 and REACH Unaffected status. Inventory availability differs, with EP3C5U256C6N showing higher stock levels (10486 pcs) compared to EP3C5U256C6 (1034 pcs).

Frequently Asked Questions (FAQ)

Q: Are EP3C5U256C6 and EP3C5U256C6N pin-compatible?

A: Yes. Both devices feature identical 256-LFBGA (14x14) packages with 182 I/O pins in the same configuration.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, from an electrical and mechanical standpoint. However, compliance requirements must be verified. If RoHS compliance is mandated, EP3C5U256C6N must be used.

Q: What is the difference between these part numbers?

A: The primary difference is RoHS compliance status. EP3C5U256C6N is RoHS Compliant; EP3C5U256C6 is RoHS non-compliant. All functional parameters are identical.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical logic element count, RAM capacity, I/O configuration, and operating specifications.

Q: Which part should I specify for new designs?

A: Specify EP3C5U256C6N for new designs unless RoHS exemption is explicitly required and documented.
