Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LFECP6E-3FN484C is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 484-BBGA package with identical physical dimensions (23x23 mm) to ensure PCB footprint compatibility and assembly process alignment.

Electrical Specifications: Supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C) must be maintained or exceeded to ensure functional equivalence in the target application.

I/O Pin Count: The substitute part must provide equal or greater I/O capacity (minimum 224 pins) to support existing circuit connections without redesign.

Logic Resources: The substitute must offer equal or greater logic element count (minimum 6100 cells) and RAM capacity (minimum 94208 bits) to accommodate the original design's computational and storage requirements.

Regulatory Compliance: REACH status and ECCN classification must remain consistent to maintain compliance with applicable regulations and export controls.

The LFE2-12E-5FN484C meets all substitution criteria as an active product from the same manufacturer family with enhanced specifications across all key parameters.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-12E-5FN484C is the qualified substitute for the obsolete LFECP6E-3FN484C. Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Regulatory Compliance: Both parts share identical REACH status (REACH Unaffected) and ECCN classification (3A991D), maintaining compliance with export control and environmental regulations without modification to procurement or documentation procedures.

Package and Electrical Compatibility: Identical package specifications (484-BBGA, 23x23 mm) and supply voltage range (1.14V ~ 1.26V) ensure direct PCB compatibility and power delivery system alignment.

Enhanced Specifications: The substitute provides increased logic element capacity (12000 vs. 6100), expanded RAM (226304 vs. 94208 bits), and additional I/O pins (297 vs. 224), offering design headroom for future enhancements without PCB redesign.

Moisture Sensitivity: Matching MSL rating (3, 168 Hours) ensures equivalent handling, storage, and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484C directly replace the LFECP6E-3FN484C on existing PCBs?

A: Yes. Both parts use the identical 484-BBGA package with matching physical dimensions (23x23 mm), pinout compatibility, and supply voltage specifications (1.14V ~ 1.26V). No PCB redesign is required.

Q: What are the key differences between these two parts?

A: The substitute (LFE2-12E-5FN484C) is from the newer ECP2 series and provides double the logic elements (12000 vs. 6100), more than double the RAM capacity (226304 vs. 94208 bits), and 73 additional I/O pins (297 vs. 224). The main part is obsolete; the substitute is in active production.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS codes (8542.39.0001). Regulatory documentation and export procedures remain unchanged.

Q: Does the substitute require different handling or storage procedures?

A: No. Both parts share the same Moisture Sensitivity Level (MSL 3, 168 Hours), so handling, storage, and assembly process requirements are identical.

Q: Why is the substitute part more expensive if it has the same package?

A: The LFE2-12E-5FN484C offers significantly enhanced specifications (double the logic elements and RAM, additional I/O capacity) within the same physical package. The price difference reflects the increased silicon capability and active production status versus the obsolete main part.

Q: Can I use the substitute in a new design?

A: Yes. The substitute is the recommended choice for new designs, offering superior specifications, active production status, and long-term availability compared to the obsolete main part.
