Substitute Part Grouping Explanation

The LFE2-20SE-7FN484C qualifies as a direct substitute based on the following criteria:

• Identical series designation (ECP2)
• Matching logic element count (21,000)
• Identical I/O pin count (331)
• Identical RAM capacity (282,624 bits)
• Identical supply voltage range (1.14V ~ 1.26V)
• Identical package specification (484-BBGA, 484-FPBGA 23x23)
• Identical operating temperature range (0°C ~ 85°C TJ)
• Identical mounting type (Surface Mount)
• Identical LAB/CLB count (2,625)

The substitution is valid at the functional and electrical level. The primary differentiator is packaging format (Tray vs. unspecified) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-20SE-7FN484C is the direct functional equivalent of the LFE2-20SE-7F484C. Selection between these parts should be based on the following factors:

Product Lifecycle: The LFE2-20SE-7F484C is obsolete, while the LFE2-20SE-7FN484C maintains active product status. For new designs or long-term procurement, the active part is preferred.

Regulatory Compliance: The LFE2-20SE-7FN484C is ROHS3 compliant, whereas the LFE2-20SE-7F484C is non-compliant. Applications subject to RoHS regulations require the compliant variant.

Packaging: The LFE2-20SE-7FN484C is supplied in Tray packaging, which may affect handling, storage, and assembly processes depending on production requirements.

Electrical and Functional Equivalence: Both parts are electrically and functionally identical across all specified parameters, including logic capacity, I/O count, supply voltage, temperature range, and package dimensions.

Frequently Asked Questions (FAQ)

Q: Are the LFE2-20SE-7F484C and LFE2-20SE-7FN484C pin-compatible?

A: Yes. Both devices use the 484-BBGA package with identical pin assignments, I/O count (331), and physical dimensions (484-FPBGA 23x23).

Q: Can the LFE2-20SE-7FN484C replace the LFE2-20SE-7F484C in existing designs?

A: Yes, at the functional and electrical level. The substitute maintains identical logic element count, RAM capacity, supply voltage range, and operating temperature specifications. Verify packaging format compatibility with your assembly process.

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). Electrical and functional specifications are identical.

Q: Does the LFE2-20SE-7FN484C require different PCB layout or assembly procedures?

A: No. Both parts share identical package specifications (484-BBGA, 23x23mm), supply voltage requirements (1.14V ~ 1.26V), and operating temperature range (0°C ~ 85°C). PCB layout and assembly procedures remain unchanged.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the LFE2-20SE-7F484C and LFE2-20SE-7FN484C have MSL 3 with a 168-hour floor life. Identical moisture handling and storage protocols apply.

Q: Are there any export or regulatory restrictions?

A: Both parts share identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications. REACH status is unaffected for both variants.
