Substitute Part Grouping Explanation

The LFE2-12E-5FN484C qualifies as a manufacturer-recommended substitute based on the following criteria:

Mechanical Compatibility:

• Identical package type: 484-BBGA
• Identical supplier device package: 484-FPBGA (23x23)
• Identical mounting type: Surface Mount
• Identical moisture sensitivity level: MSL 3 (168 Hours)

Electrical Compatibility:

• Identical supply voltage range: 1.14V ~ 1.26V
• Identical operating temperature range: 0°C ~ 85°C (TJ)
• Identical ECCN classification: 3A991D
• Identical HTSUS code: 8542.39.0001

Performance Enhancement: The substitute part provides increased logic capacity (12000 elements vs. 6100), expanded I/O capability (297 pins vs. 224), and greater RAM resources (226304 bits vs. 94208 bits), making it suitable for designs requiring additional functionality within the same physical footprint and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-12E-5FN484C is the manufacturer-recommended substitute for the obsolete LFECP6E-5FN484C. Selection of this substitute is supported by:

• Identical physical package dimensions and mounting specifications
• Matching electrical supply voltage and operating temperature ranges
• Equivalent regulatory compliance (REACH Unaffected, identical ECCN and HTSUS classifications)
• Active product status ensuring continued availability and manufacturing support
• RoHS3 compliance of the substitute part

The substitute part maintains full mechanical and electrical compatibility while providing enhanced logic capacity, I/O count, and memory resources. No design modifications to power delivery, thermal management, or PCB layout are required due to identical package specifications.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484C directly replace the LFECP6E-5FN484C in existing designs?

A: Yes. Both parts share identical package dimensions (484-FPBGA 23x23), supply voltage requirements (1.14V ~ 1.26V), operating temperature range (0°C ~ 85°C), and moisture sensitivity level (MSL 3). No PCB modifications or power supply redesign is necessary.

Q: What are the key differences between these parts?

A: The LFE2-12E-5FN484C provides doubled logic element capacity (12000 vs. 6100), increased I/O pins (297 vs. 224), and expanded RAM (226304 vs. 94208 bits). The substitute represents a newer ECP2 series device with enhanced functionality in the same physical footprint.

Q: Are there compliance or regulatory differences?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS codes (8542.39.0001). The substitute part adds RoHS3 compliance certification.

Q: Why is the original part classified as obsolete?

A: The LFECP6E-5FN484C belongs to the legacy ECP series. Lattice Semiconductor has transitioned production to the newer ECP2 series, of which the LFE2-12E-5FN484C is an active product with ongoing manufacturing support.

Q: Are there any design considerations when switching to the substitute?

A: Design considerations are limited to firmware or HDL code compatibility with the ECP2 architecture. The physical and electrical interfaces remain unchanged, eliminating hardware redesign requirements.
