Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484I be used as a direct replacement for the LFEC6E-3FN484I?

A: Yes. Both devices share identical package dimensions (484-FPBGA 23x23), supply voltage range (1.14V ~ 1.26V), operating temperature range (-40°C ~ 100°C), and MSL rating (3). The LFE2-12E-5FN484I provides additional logic resources and I/O capacity within the same physical footprint.

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

A: The LFE2-12E-5FN484I offers doubled logic element count (12000 vs. 6100), increased I/O capacity (297 vs. 224), and expanded RAM (226304 vs. 94208 bits). The LFE2-12E-5FN484I belongs to the active ECP2 series, while the LFEC6E-3FN484I is an obsolete EC series device.

Q: Are there any voltage or thermal considerations when substituting?

A: No. Both devices operate within identical voltage ranges (1.14V ~ 1.26V) and temperature ranges (-40°C ~ 100°C TJ), eliminating the need for power supply or thermal management modifications.

Q: Does the substitute part require different handling or storage conditions?

A: No. Both devices share identical MSL ratings (3, 168 Hours), requiring the same moisture control and storage protocols.

Q: What compliance certifications apply to the substitute part?

A: The LFE2-12E-5FN484I is RoHS3 compliant and maintains REACH Unaffected status. Both devices carry identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications.
