Substitute Part Grouping Explanation

Substitution of the LFE2M20E-7F484C is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical ECP2M series designation
• Logic Capacity: Matching 19,000 logic elements and 2,375 LABs/CLBs
• Memory Configuration: Identical 1,246,208 bits of embedded RAM
• I/O Count: Matching 304 I/O pins
• Electrical Specifications: Identical supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C)
• Package Specification: Identical 484-BBGA package and 484-FPBGA (23x23) supplier device package
• Mechanical Compatibility: Surface mount mounting type with identical MSL rating

The substitute part LFE2M20E-7FN484C meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The LFE2M20E-7FN484C is the direct equivalent substitute for the obsolete LFE2M20E-7F484C. Selection of the substitute part is justified on the following basis:

• Functional Equivalence: All logic capacity, memory, I/O, electrical, and thermal specifications are identical.
• Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturer support.
• Regulatory Compliance: The substitute part is ROHS3 compliant, providing improved environmental and regulatory alignment compared to the non-compliant main part.
• Package Compatibility: Identical 484-BBGA package and MSL rating ensure direct PCB compatibility without redesign.
• Inventory Availability: The substitute part is available in significantly higher quantities (5,425 pcs vs. 926 pcs).

Frequently Asked Questions (FAQ)

Q: Can the LFE2M20E-7FN484C be used as a direct replacement for the LFE2M20E-7F484C?

A: Yes. Both parts are identical in logic architecture, capacity, memory, I/O configuration, electrical specifications, and package format. The substitute part is a direct functional equivalent.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. tray). All technical specifications are identical.

Q: Are there any PCB layout or design changes required when switching to the substitute part?

A: No. Both parts use the identical 484-BBGA package with 23x23mm dimensions and the same MSL rating. No PCB redesign is necessary.

Q: Why should I select the substitute part over the main part?

A: The main part is obsolete and has limited inventory. The substitute part is active, more readily available, and meets ROHS3 compliance requirements.

Q: Are the electrical and thermal operating ranges identical?

A: Yes. Both parts operate at 1.14V to 1.26V supply voltage and 0°C to 85°C junction temperature range.
