Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFECP10E-4FN484C is determined by the following critical parameters:

Electrical Compatibility: Supply voltage range (1.14V ~ 1.26V), operating temperature range (0°C ~ 85°C), and logic element count must meet or exceed the original specification.

Mechanical Compatibility: Package type (484-BBGA), physical dimensions (23x23), and mounting type (Surface Mount) must be identical to ensure PCB-level compatibility without redesign.

I/O Pin Count: The substitute must provide a minimum of 288 I/O pins to maintain signal routing equivalence.

Regulatory Compliance: REACH status and ECCN classification must remain consistent for supply chain and export compliance.

The LFE2-12E-5FN484C qualifies as a direct substitute based on matching package specifications, identical supply voltage range, identical operating temperature range, identical mounting type, and superior logic element capacity (12,000 vs. 10,200), while maintaining the same 484-BBGA footprint and MSL rating.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-12E-5FN484C is the qualified substitute for the obsolete LFECP10E-4FN484C based on the following engineering criteria:

Package Compatibility: Both devices use the 484-BBGA package with identical 23x23mm physical dimensions, enabling direct PCB-level replacement without layout modifications.

Electrical Equivalence: Identical supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C) ensure compatibility with existing power delivery and thermal management infrastructure.

Pin Count Sufficiency: The substitute provides 297 I/O pins compared to the original 288 I/O pins, maintaining signal routing capability with additional I/O availability.

Product Status: The LFE2-12E-5FN484C is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Regulatory Alignment: Both devices share identical REACH status, ECCN classification, and HTSUS codes, maintaining compliance requirements for procurement and export.

Logic Element Enhancement: The substitute provides 12,000 logic elements versus 10,200 in the original, offering increased design capacity for future enhancements or feature additions.

Frequently Asked Questions (FAQ)

Q: Can the LFE2-12E-5FN484C be used as a direct replacement for the LFECP10E-4FN484C?

A: Yes. Both devices share identical package specifications (484-BBGA, 23x23mm), supply voltage range (1.14V ~ 1.26V), operating temperature range (0°C ~ 85°C), and mounting type (Surface Mount). The substitute provides additional I/O pins (297 vs. 288) and logic elements (12,000 vs. 10,200), making it functionally compatible without PCB redesign.

Q: What are the key differences between these two FPGA devices?

A: The primary differences are series generation (ECP vs. ECP2), logic element count (10,200 vs. 12,000), I/O pin count (288 vs. 297), total RAM bits (282,624 vs. 226,304), and product status (Obsolete vs. Active). The substitute offers more logic capacity and current availability, while the original provided more embedded RAM.

Q: Are the package dimensions identical?

A: Yes. Both devices use the 484-FPBGA package with identical 23x23mm dimensions. No PCB layout modifications are required for substitution.

Q: Does the substitute maintain the same moisture sensitivity level?

A: Yes. Both devices have MSL rating 3 (168 Hours), requiring identical handling and storage protocols.

Q: Are regulatory certifications equivalent?

A: Yes. Both devices share identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS code (8542.39.0001), maintaining compliance for procurement and export requirements.

Q: Why is the original part obsolete?

A: The LFECP10E-4FN484C belongs to the ECP series, which has been superseded by the ECP2 series. The LFE2-12E-5FN484C represents the current-generation equivalent with enhanced logic capacity and active production status.
