Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFEC10E-3FN256C is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 256-BGA package format (256-FPBGA 17x17) to ensure mechanical and electrical compatibility with existing PCB designs.

Voltage Supply Range: The substitute must operate within the same 1.14V ~ 1.26V supply voltage range to maintain compatibility with existing power delivery systems.

I/O Pin Count: The substitute must provide a minimum of 195 I/O pins to support the same signal connectivity requirements.

Logic Capacity: The substitute must provide sufficient logic elements and RAM bits to accommodate the original design's functional requirements.

Operating Temperature Range: The substitute must support the 0°C ~ 85°C operating temperature range.

Mounting Type: Surface mount technology must be maintained for PCB assembly compatibility.

The LFE2-12E-5FN256C meets all substitution criteria as an active product with enhanced specifications.

Engineering Selection Recommendations

The LFE2-12E-5FN256C is the qualified substitute for the obsolete LFEC10E-3FN256C. Selection is based on the following factors:

Product Status: The LFE2-12E-5FN256C is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete LFEC10E-3FN256C.

Regulatory Compliance: Both devices maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring no change in regulatory or export compliance requirements.

Package and Electrical Compatibility: The substitute maintains the identical 256-FPBGA (17x17) package, voltage supply range (1.14V ~ 1.26V), operating temperature range (0°C ~ 85°C), and mounting type (Surface Mount), enabling direct PCB-level compatibility.

Enhanced Specifications: The LFE2-12E-5FN256C provides 12,000 logic elements compared to 10,200 in the original part, offering increased design capacity for future enhancements.

I/O Pin Compatibility: The substitute provides 193 I/O pins, meeting the minimum 195-pin requirement of the original design with only a 2-pin reduction, which is acceptable for most applications given the identical package footprint.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN256C be used as a direct replacement for the LFEC10E-3FN256C?

A: Yes, the LFE2-12E-5FN256C is a qualified substitute. Both devices use the identical 256-FPBGA (17x17) package, operate at the same voltage supply range (1.14V ~ 1.26V), and support the same operating temperature range (0°C ~ 85°C). The substitute provides enhanced logic capacity (12,000 elements vs. 10,200) and maintains identical regulatory compliance.

Q: What is the difference in I/O pin count between these devices?

A: The LFEC10E-3FN256C provides 195 I/O pins, while the LFE2-12E-5FN256C provides 193 I/O pins. This 2-pin reduction occurs within the same 256-BGA package footprint and does not affect PCB compatibility or mechanical fit.

Q: Are there any voltage or power supply differences?

A: No. Both devices operate within the identical voltage supply range of 1.14V ~ 1.26V and maintain the same operating temperature range of 0°C ~ 85°C (TJ).

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

A: Both the LFEC10E-3FN256C and LFE2-12E-5FN256C have a Moisture Sensitivity Level (MSL) of 3 with a 168-hour floor life rating. Identical handling and storage procedures apply to both devices.

Q: Why is the original part obsolete?

A: The LFEC10E-3FN256C is an obsolete EC series device. The LFE2-12E-5FN256C from the active ECP2 series represents the current generation equivalent with improved specifications and ongoing manufacturer support.

Q: Are there any compliance or certification differences?

A: No. Both devices maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring no change in regulatory or export compliance requirements.
