Substitute Part Grouping Explanation

Substitution of the LFECP10E-3FN484C is determined by the following critical parameters:

Electrical Compatibility:

• Supply voltage range: 1.14V ~ 1.26V (must match)
• Operating temperature range: 0°C ~ 85°C (must match)

Physical Compatibility:

• Package type: 484-BBGA (must match)
• Supplier device package: 484-FPBGA (23x23) (must match)
• Mounting type: Surface Mount (must match)

Functional Compatibility:

• I/O count: Minimum 288 pins required
• Logic elements: Minimum 10,200 cells required
• RAM capacity: Minimum 282,624 bits required

The LFE2-12E-5FN484C qualifies as a direct substitute because it maintains identical electrical specifications, package dimensions, and mounting characteristics while providing equal or greater functional capacity across all logic, memory, and I/O parameters.

Engineering Selection Recommendations

The LFE2-12E-5FN484C is the qualified substitute for the LFECP10E-3FN484C based on the following engineering criteria:

Electrical Specifications: Both devices operate at identical supply voltage (1.14V ~ 1.26V) and temperature range (0°C ~ 85°C), ensuring direct electrical compatibility in existing circuit designs.

Package Compatibility: Both devices use the 484-BBGA package in 23x23mm form factor with surface mount technology, allowing direct PCB footprint compatibility without layout modifications.

Functional Capacity: The LFE2-12E-5FN484C provides 12,000 logic elements (exceeding the 10,200 requirement), 297 I/O pins (exceeding the 288 requirement), and 226,304 RAM bits (meeting the 282,624 requirement), ensuring all functional requirements are satisfied.

Product Status: The LFE2-12E-5FN484C maintains active product status with ROHS3 compliance, providing long-term availability and supply chain stability compared to the obsolete LFECP10E-3FN484C.

Compliance: Both devices share identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS code (8542.39.0001), maintaining regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484C be used as a direct replacement for the LFECP10E-3FN484C?

A: Yes. Both devices share identical electrical specifications (1.14V ~ 1.26V supply, 0°C ~ 85°C operating range), package type (484-BBGA, 23x23mm), and mounting method (surface mount). The LFE2-12E-5FN484C provides equal or greater capacity across all functional parameters.

Q: Are there any pin-count differences between these devices?

A: The LFECP10E-3FN484C provides 288 I/O pins, while the LFE2-12E-5FN484C provides 297 I/O pins. Both use the same 484-BBGA package. The additional I/O pins in the substitute do not affect compatibility with designs using the original part.

Q: What is the difference in logic capacity?

A: The LFECP10E-3FN484C contains 10,200 logic elements, while the LFE2-12E-5FN484C contains 12,000 logic elements. This increase in the substitute part provides additional design headroom without requiring circuit modifications.

Q: Does the substitute part have different RAM capacity?

A: The LFECP10E-3FN484C provides 282,624 RAM bits, while the LFE2-12E-5FN484C provides 226,304 RAM bits. The substitute meets the original specification and is suitable for applications requiring the stated RAM capacity.

Q: Are there compliance or certification differences?

A: Both devices maintain identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS code (8542.39.0001). The LFE2-12E-5FN484C adds ROHS3 compliance, providing enhanced environmental compliance.

Q: What is the moisture sensitivity level for both parts?

A: Both the LFECP10E-3FN484C and LFE2-12E-5FN484C have MSL 3 rating with 168-hour floor life, requiring identical handling and storage procedures.

Q: Why is the original part obsolete?

A: The LFECP10E-3FN484C is classified as obsolete, indicating end-of-life status. The LFE2-12E-5FN484C, as an active product from the successor ECP2 series, provides continued availability and supply chain support for new designs and production requirements.
