Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 252M-42LF carries Obsolete status, which restricts long-term availability and manufacturer support. The 5L35021B-000NDGI maintains Active product status, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Compliance and Certification: The 5L35021B-000NDGI includes the following compliance documentation:

• REACH Status: REACH Unaffected
• ECCN Classification: EAR99
• HTSUS Code: 8542.39.0001
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Supply Chain Reliability: Current inventory levels support both components. However, the Active status of the substitute ensures replenishment capability and eliminates obsolescence risk for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Why is the 252M-42LF classified as Obsolete? A: Obsolete classification indicates the manufacturer has discontinued production and support. This is a standard lifecycle designation for components no longer in active manufacturing.

Q: Is the 5L35021B-000NDGI a direct replacement for the 252M-42LF? A: The 5L35021B-000NDGI is designated by Renesas Electronics Corporation as the manufacturer-recommended substitute for the 252M-42LF within the Clock/Timing category.
