Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFXP15E-3FN484C is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 484-BBGA package format with identical 23x23mm dimensions to ensure PCB-level compatibility
• Voltage Supply Range: Substitute parts must operate within the 1.14V ~ 1.26V supply voltage specification
• Operating Temperature Range: Substitute parts must support the 0°C ~ 85°C (TJ) operating temperature range
• Mounting Type: Surface mount technology must be maintained
• Moisture Sensitivity Level: MSL 3 classification ensures equivalent handling and storage requirements

The LFXP2-17E-5FN484C qualifies as a substitute based on matching all critical parameters while offering enhanced logic capacity and I/O count within the same physical package footprint.

Parameter Comparison

Engineering Selection Recommendations

The LFXP2-17E-5FN484C is the qualified substitute for the obsolete LFXP15E-3FN484C based on the following factors:

• Package Equivalence: Identical 484-BBGA (23x23mm) package ensures direct PCB compatibility without layout modifications
• Electrical Compatibility: Matching supply voltage range (1.14V ~ 1.26V) and operating temperature range (0°C ~ 85°C) ensure functional interchangeability in existing designs
• Product Status: The substitute is in active production status, ensuring long-term availability and supply chain stability
• Compliance: ROHS3 compliance of the substitute part meets current environmental and regulatory requirements
• Enhanced Capacity: The substitute provides increased logic elements (17,000 vs. 15,000) and additional I/O pins (358 vs. 300), offering design headroom for future requirements

Frequently Asked Questions (FAQ)

Q: Can the LFXP2-17E-5FN484C be used as a direct replacement for the LFXP15E-3FN484C?

A: Yes. Both devices share identical package specifications (484-BBGA, 23x23mm), supply voltage range (1.14V ~ 1.26V), and operating temperature range (0°C ~ 85°C). PCB-level compatibility is maintained without design modifications.

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

A: The LFXP2-17E-5FN484C offers 17,000 logic elements compared to 15,000 in the LFXP15E-3FN484C, and provides 358 I/O pins versus 300. The substitute has lower total RAM bits (282,624 vs. 331,776). The LFXP2-17E-5FN484C is in active production status, whereas the original part is obsolete.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL) 3 classification with 168-hour reflow window, requiring equivalent handling and storage protocols.

Q: Does the LFXP2-17E-5FN484C meet current compliance standards?

A: Yes. The substitute is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What should be considered when selecting between these parts?

A: Selection should be based on design requirements for logic element count, I/O pin count, and RAM capacity. The substitute's higher logic element and I/O count may provide design flexibility, while the original part's higher RAM capacity may be required for specific applications. Product availability and supply chain considerations favor the active substitute part.
