Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFXP15C-4FN484C is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 484-BBGA package format to ensure PCB footprint and mechanical fit compatibility.
• Mounting Type: Surface mount requirement must be maintained.
• Operating Temperature Range: The substitute must support the 0°C ~ 85°C operating window.
• I/O Pin Count: The substitute must provide equal or greater I/O capacity (minimum 300 pins) to support existing signal routing.
• Logic Element Capacity: The substitute must provide equal or greater logic element count to accommodate design complexity.
• Manufacturer Continuity: Lattice Semiconductor Corporation maintains design compatibility within the XP and XP2 series families.

The LFXP2-17E-5FN484C qualifies as a direct substitute based on identical package geometry, matching operating temperature range, equivalent mounting type, and superior logic element and I/O capacity within the same manufacturer ecosystem.

Engineering Selection Recommendations

The LFXP2-17E-5FN484C is the manufacturer-recommended substitute for the obsolete LFXP15C-4FN484C. Selection of this substitute is supported by the following factors:

• Active Product Status: The LFXP2-17E-5FN484C maintains active production status, ensuring long-term availability and supply chain continuity.
• Identical Package Geometry: The 484-BBGA package format is identical, eliminating PCB redesign requirements.
• Enhanced Capacity: The substitute provides 17,000 logic elements and 358 I/O pins, exceeding the original part specifications and providing design margin for future enhancements.
• Compliance Certifications: Both parts maintain identical Moisture Sensitivity Level (MSL 3) and REACH compliance status.
• Temperature Compatibility: Operating temperature range remains unchanged at 0°C ~ 85°C.

Design implementation with the LFXP2-17E-5FN484C requires verification of voltage supply requirements, as the substitute operates at 1.14V ~ 1.26V compared to the original 1.71V ~ 3.465V specification. Power supply circuitry must be evaluated and adjusted accordingly.

Frequently Asked Questions (FAQ)

Q: Can the LFXP2-17E-5FN484C be used as a direct drop-in replacement for the LFXP15C-4FN484C?

A: The LFXP2-17E-5FN484C is mechanically and electrically compatible at the package level (484-BBGA), but power supply voltage requirements differ. The substitute requires 1.14V ~ 1.26V supply voltage versus the original 1.71V ~ 3.465V. Power delivery circuitry must be redesigned to accommodate this specification change.

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

A: The primary differences are product status (obsolete versus active), logic element capacity (15,000 versus 17,000), I/O pin count (300 versus 358), and supply voltage range. The substitute provides enhanced capacity within an identical package footprint.

Q: Is PCB redesign required when switching to the LFXP2-17E-5FN484C?

A: PCB footprint redesign is not required due to identical 484-BBGA package geometry. However, power supply circuit modifications are necessary to accommodate the different voltage specification.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical Moisture Sensitivity Level (MSL 3) and REACH compliance status. The substitute includes RoHS3 compliance certification.

Q: What is the inventory status of these parts?

A: The LFXP15C-4FN484C has 3,284 units in stock as new original inventory. The LFXP2-17E-5FN484C has 1,445 units in stock as new original inventory in tray packaging.
