Parameter Comparison

Engineering Selection Recommendations

The LFE3-70EA-6FN672C is the direct substitute for the LFE3-70E-6FN672C. Both devices share identical electrical and mechanical specifications, including logic capacity, I/O configuration, memory architecture, voltage requirements, and package dimensions. The primary distinction is product lifecycle status: the original part is obsolete, while the substitute is in active production.

The substitute part offers ROHS3 compliance, providing enhanced environmental and regulatory alignment for new designs and production continuity. The identical parameter set ensures pin-for-pin and functional compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are the LFE3-70E-6FN672C and LFE3-70EA-6FN672C pin-compatible?

A: Yes. Both devices use the 672-BBGA package with identical pin assignments, voltage levels, and I/O configuration. No PCB redesign is required for substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and compliance certification. The LFE3-70E-6FN672C is obsolete, while the LFE3-70EA-6FN672C is actively produced and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use the LFE3-70EA-6FN672C as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical logic capacity (67,000 elements), I/O count (380 pins), memory configuration (4,526,080 bits), voltage supply range (1.14V ~ 1.26V), and operating temperature range (0°C ~ 85°C). No firmware or design changes are necessary.

Q: What is the package footprint for both parts?

A: Both parts use a 672-FPBGA package with 27x27mm dimensions. The 672-BBGA designation indicates the ball grid array configuration with 672 contact points.

Q: Are there any compliance differences between these parts?

A: The LFE3-70EA-6FN672C includes ROHS3 compliance certification, while the obsolete LFE3-70E-6FN672C does not specify this status. Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications.
