Substitute Part Grouping Explanation

The LFE2M20SE-5FN484C qualifies as a direct substitute based on the following criteria:

• Identical base product number (LFE2M20)
• Matching logic element count (19,000)
• Matching RAM capacity (1,246,208 bits)
• Matching I/O pin count (304)
• Identical supply voltage range (1.14V ~ 1.26V)
• Identical operating temperature range (0°C ~ 85°C)
• Identical package specification (484-BBGA / 484-FPBGA 23x23)
• Identical mounting type (Surface Mount)
• Identical MSL rating (3 / 168 Hours)

The primary distinction between the main part and substitute is product status and compliance certification, not functional or electrical parameters.

Engineering Selection Recommendations

The LFE2M20SE-5FN484C is the direct equivalent substitute for the LFE2M20SE-5F484C. Selection between these parts should be based on the following factors:

• The LFE2M20SE-5F484C is classified as obsolete and carries RoHS non-compliant status, limiting its suitability for new designs or production environments with regulatory compliance requirements.
• The LFE2M20SE-5FN484C maintains active product status and achieves ROHS3 compliance, making it the preferred choice for applications requiring current manufacturing support and environmental regulation adherence.
• Both parts are electrically and mechanically identical across all functional parameters, ensuring direct substitution without design modification.
• The LFE2M20SE-5FN484C is supplied in Tray packaging, whereas the main part packaging type is not specified.

Frequently Asked Questions (FAQ)

Q: Can the LFE2M20SE-5FN484C be used as a direct replacement for the LFE2M20SE-5F484C?

A: Yes. Both parts share identical electrical specifications, logic element count, RAM capacity, I/O configuration, supply voltage, operating temperature range, and package dimensions. No design modifications are required for substitution.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. Tray). Functional and electrical parameters are identical.

Q: Are there any compatibility concerns with the 484-BBGA package?

A: No. Both parts use the identical 484-BBGA package specification (484-FPBGA 23x23) with surface mount mounting type. PCB layout and assembly processes remain unchanged.

Q: Does the substitute part require different handling or storage conditions?

A: Both parts carry identical Moisture Sensitivity Level (MSL) ratings of 3 with 168-hour exposure limits. Storage and handling procedures are equivalent.

Q: Why is the LFE2M20SE-5F484C marked as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The LFE2M20SE-5FN484C provides continued access to equivalent ECP2M FPGA functionality with active manufacturing support.
