Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFEC10E-3FN484I is determined by the following critical parameters:

Electrical Compatibility:

• Voltage supply range: 1.14V – 1.26V (core voltage)
• Operating temperature range: -40°C to +100°C (TJ)

Mechanical Compatibility:

• Package type: 484-BBGA
• Supplier device package: 484-FPBGA (23×23)
• Mounting type: Surface Mount
• Pin count: 288 I/O minimum

Regulatory & Environmental:

• Moisture Sensitivity Level (MSL): 3 (168 Hours)
• REACH Status: REACH Unaffected
• ECCN: 3A991D
• HTSUS: 8542.39.0001

The LFE2-12E-5FN484I qualifies as a direct substitute because it maintains identical electrical supply voltage, operating temperature range, package footprint, MSL rating, and regulatory compliance. The ECP2 series enhancement provides increased logic capacity (12,000 elements vs. 10,200) and I/O count (297 vs. 288) while preserving pinout compatibility and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The LFE2-12E-5FN484I is suitable for direct substitution in applications currently using the LFEC10E-3FN484I. The substitute maintains identical electrical supply voltage (1.14V – 1.26V), operating temperature range (-40°C to +100°C), package footprint (484-FPBGA 23×23), and regulatory compliance (REACH Unaffected, ECCN 3A991D, HTSUS 8542.39.0001).

Product Status Advantage:

The LFE2-12E-5FN484I is classified as Active, ensuring ongoing availability and manufacturing support. The LFEC10E-3FN484I is Obsolete, making the substitute the appropriate choice for new designs and production continuity.

Compliance & Certification:

Both devices share identical Moisture Sensitivity Level (MSL 3, 168 Hours) and REACH compliance status, ensuring equivalent handling and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484I be used as a direct replacement for the LFEC10E-3FN484I?

A: Yes. Both devices operate at identical core voltage (1.14V – 1.26V), share the same operating temperature range (-40°C to +100°C), use the same 484-BBGA package footprint (484-FPBGA 23×23), and maintain identical MSL and regulatory compliance ratings.

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

A: The LFE2-12E-5FN484I offers increased logic capacity (12,000 elements vs. 10,200), additional I/O pins (297 vs. 288), and represents a newer technology generation (ECP2 vs. EC series). The substitute has different internal RAM architecture (226,304 bits vs. 282,624 bits). The LFE2-12E-5FN484I is in active production, while the LFEC10E-3FN484I is obsolete.

Q: Are the pin assignments identical between these parts?

A: Both devices use the 484-BBGA package with identical footprint dimensions (23×23 mm). The LFE2-12E-5FN484I provides 297 I/O pins compared to 288 on the LFEC10E-3FN484I. Pin compatibility must be verified against specific application requirements and device datasheets.

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

A: Both the LFEC10E-3FN484I and LFE2-12E-5FN484I are rated MSL 3 (168 Hours), requiring identical handling and storage conditions.

Q: Are there any regulatory or export restrictions?

A: Both devices share identical export classification (ECCN 3A991D) and tariff classification (HTSUS 8542.39.0001). Both are REACH Unaffected, indicating equivalent environmental compliance.

Q: Why is the LFEC10E-3FN484I obsolete?

A: The EC series has been superseded by the ECP2 series, which offers improved performance and logic capacity. The LFE2-12E-5FN484I represents the current-generation equivalent in the same package class.
