Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LFE2-6SE-5F256C is determined by strict equivalence across the following parameters:

• Logic element count: 6000 cells
• I/O pin count: 190 pins
• RAM capacity: 56320 bits
• Supply voltage range: 1.14V ~ 1.26V
• Package type: 256-BGA (256-FPBGA 17x17)
• Operating temperature range: 0°C ~ 85°C (TJ)
• Mounting configuration: Surface Mount

The substitute part LFE2-6SE-5FN256C meets all electrical and mechanical requirements for direct substitution. The primary distinction lies in product status and packaging format, not in functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The LFE2-6SE-5FN256C is the direct substitute for the obsolete LFE2-6SE-5F256C. Both parts are electrically and mechanically identical across all functional parameters. The substitute part offers two significant advantages: active product status from the manufacturer and ROHS3 compliance certification. The original part carries RoHS non-compliant status, which may present procurement or regulatory constraints in certain applications or regions.

Selection between these parts should be based on compliance requirements and supply chain considerations. For new designs or systems requiring RoHS compliance, the LFE2-6SE-5FN256C is the appropriate choice. For legacy system maintenance where RoHS compliance is not a requirement, either part functions identically from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Are the LFE2-6SE-5F256C and LFE2-6SE-5FN256C pin-compatible?

A: Yes. Both parts use the 256-BGA package in 17x17 configuration with 190 I/O pins. Pin assignments and electrical characteristics are identical.

Q: Can the LFE2-6SE-5FN256C replace the LFE2-6SE-5F256C in existing PCB designs?

A: Yes. The substitute part is mechanically and electrically equivalent. No PCB redesign is required.

Q: What is the difference between the tube and tray packaging formats?

A: Packaging format affects handling, storage, and automated assembly processes. Tube packaging (original part) and tray packaging (substitute part) are both standard formats. Selection depends on manufacturing process requirements and inventory management practices.

Q: Why is the original part marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The substitute part maintains active status, ensuring continued availability and manufacturer support.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical or functional performance. Both parts operate identically within specified electrical parameters.

Q: Are the moisture sensitivity levels identical?

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