Substitute Part Grouping Explanation

The substitute part 5L35023B-000NLGI is identified as the manufacturer-recommended equivalent for the obsolete 290G-18LF. This substitution is based on the following alignment criteria:

Common Classification Parameters:

• Manufacturer: Both parts are manufactured by Renesas Electronics Corporation
• Category: Both parts function within the Clock/Timing component category
• REACH Compliance: Both parts maintain REACH Unaffected status, ensuring regulatory consistency
• Functional Purpose: Both serve clock generation and timing functions within electronic systems

The 5L35023B-000NLGI represents an active product with ongoing manufacturer support, making it the appropriate path forward for applications previously served by the 290G-18LF.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The 5L35023B-000NLGI is the designated active substitute and should be selected for all new clock/timing applications. This part carries Active product status with full manufacturer support and maintains REACH compliance. The EAR99 ECCN classification provides standard export control treatment.

For Existing Inventory Management: The 290G-18LF remains available with 882 pieces in current stock. However, transition planning to the 5L35023B-000NLGI is necessary as the obsolete part will eventually reach end-of-life for procurement. The substitute part is currently available with 919 pieces in inventory, supporting transition requirements.

Compliance Considerations: Both parts maintain REACH Unaffected status, ensuring regulatory consistency across substitution. The transition from OBSOLETE to EAR99 ECCN classification reflects the active status of the substitute part and does not introduce additional export control restrictions.

Frequently Asked Questions (FAQ)
