Substitute Part Grouping Explanation

Substitution eligibility for the EP3C55F484C7 is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must be Intel Cyclone® III devices
• Base Product Number: EP3C55 designation ensures identical logic element count (55,856), RAM capacity (2,396,160 bits), and I/O count (327)
• Package Specification: 484-BGA (484-FBGA 23x23) ensures mechanical and electrical compatibility with existing PCB designs
• Electrical Specifications: Supply voltage range (1.15V ~ 1.25V) and operating temperature range (0°C ~ 85°C) must match
• Mounting Type: Surface Mount configuration must remain consistent

The EP3C55F484C7N qualifies as a direct substitute based on identical functional specifications and package configuration. The primary distinction between the main part and its substitute relates to compliance certifications and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both EP3C55F484C7 and EP3C55F484C7N are functionally equivalent devices with identical logic density, memory capacity, I/O configuration, and electrical characteristics. Selection between these parts should be based on compliance requirements and supply availability.

The EP3C55F484C7N is RoHS Compliant, making it suitable for applications subject to RoHS directives and regulations. The EP3C55F484C7 is RoHS non-compliant and should be selected only when RoHS compliance is not a design or procurement requirement.

Both devices maintain REACH Unaffected status and identical Moisture Sensitivity Level (MSL 3, 168 Hours) specifications. Both are in active production status, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can EP3C55F484C7N be used as a direct replacement for EP3C55F484C7 in existing designs?

A: Yes. Both devices are functionally identical with matching logic element count, RAM capacity, I/O configuration, package specification, and electrical parameters. No design modifications are required for substitution.

Q: What is the primary difference between EP3C55F484C7 and EP3C55F484C7N?

A: The primary difference is RoHS compliance status. EP3C55F484C7N is RoHS Compliant, while EP3C55F484C7 is RoHS non-compliant. All functional and electrical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both devices use the 484-BGA package (484-FBGA 23x23) with identical pinout and mechanical specifications. PCB designs are fully compatible.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS compliance, specify EP3C55F484C7N. For applications without RoHS requirements, either part is acceptable based on availability and cost considerations.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both devices have Moisture Sensitivity Level (MSL) 3 with a 168-hour floor life specification. Identical handling and storage procedures apply to both parts.
