Substitute Part Grouping Explanation

Substitution of the 252MLFT with the 5L35021B-000NDGI8 is based on the following criteria:

Manufacturer Alignment: Both components are manufactured by Renesas Electronics Corporation, ensuring consistency in design philosophy, quality standards, and technical support protocols.

Functional Category: Both parts operate within the Clock/Timing functional category, indicating they serve equivalent timing and clock generation purposes within electronic systems.

Component Classification: Both are classified as integrated circuits (IC), confirming functional equivalence at the component level.

Manufacturer Recommendation: The 5L35021B-000NDGI8 is explicitly designated as the manufacturer-recommended substitute, indicating Renesas Electronics Corporation has validated this replacement for the obsolete 252MLFT.

Active Product Status: The substitute part maintains active product status with ongoing manufacturer support, ensuring long-term availability and technical documentation access.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The 5L35021B-000NDGI8 is the appropriate selection. This part carries active product status, ensuring manufacturer support, technical documentation availability, and long-term supply chain reliability. The active status eliminates obsolescence risk inherent in the 252MLFT.

For Maintenance and Repair: Original 252MLFT units remain available (1108 pieces in stock). However, for applications requiring extended operational life or future component replenishment, transition to the 5L35021B-000NDGI8 is recommended to avoid future obsolescence constraints.

Compliance Considerations: The 5L35021B-000NDGI8 carries verified REACH compliance (REACH Unaffected) and EAR99 export classification, meeting regulatory requirements for commercial and industrial applications. Moisture Sensitivity Level 1 (Unlimited) indicates minimal handling restrictions during assembly and storage.

Packaging Transition: The substitute part is supplied in Tape & Reel (TR) format with 20QFN package configuration. Design and assembly processes must accommodate this packaging specification.

Frequently Asked Questions (FAQ)

Q: Can the 5L35021B-000NDGI8 directly replace the 252MLFT in existing designs?

A: The 5L35021B-000NDGI8 is the manufacturer-recommended substitute for the obsolete 252MLFT. Both components are Clock/Timing ICs from Renesas Electronics Corporation. However, the substitute part features a 20QFN package in Tape & Reel format, which may differ from the original packaging. PCB layout and assembly process compatibility must be verified before implementation.

Q: What is the significance of the obsolete status for the 252MLFT?

A: Obsolete status indicates the 252MLFT is no longer manufactured or actively supported by Renesas Electronics Corporation. While current inventory exists (1108 pieces), future availability cannot be guaranteed. For applications requiring long-term component availability, the active-status 5L35021B-000NDGI8 is the appropriate choice.

Q: Are there any regulatory or compliance differences between these parts?

A: The 5L35021B-000NDGI8 carries documented REACH compliance status (REACH Unaffected) and EAR99 export classification. The original 252MLFT compliance documentation is not provided in this reference. For applications subject to regulatory requirements, the substitute part's verified compliance status provides assurance.

Q: What does Moisture Sensitivity Level 1 mean for the 5L35021B-000NDGI8?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control measures during storage or handling. This classification simplifies inventory management and assembly logistics compared to higher MSL ratings.

Q: How should the packaging transition from the original part to the substitute be managed?

A: The 5L35021B-000NDGI8 is supplied in Tape & Reel (TR) format with 20QFN package configuration. Assembly equipment must be compatible with this package type. Design files, pick-and-place programs, and reflow profiles may require adjustment to accommodate the new package specification.
