Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFEC10E-4FN484C is determined by the following critical parameters:

Electrical Compatibility: Supply voltage range (1.14V – 1.26V) and operating temperature range (0°C – 85°C) must match or exceed the original specification.

Mechanical Compatibility: Package type must be 484-BBGA with identical pin count and footprint (23×23 mm) to ensure PCB-level compatibility without redesign.

I/O Pin Count: Minimum 288 I/O pins required to maintain signal routing equivalence.

Logic Capacity: Minimum 10,200 logic elements to support functional parity.

The LFE2-12E-5FN484C meets all substitution criteria through identical electrical specifications, matching package geometry, and enhanced logic capacity (12,000 elements) with compatible I/O count (297 pins).
