Engineering Selection Recommendations

For Obsolete Part Replacement:

The 5L35021B-000NDGI8 is the qualified substitute for the obsolete 252M-64LFT. Selection of this substitute is supported by:

1. Manufacturer Continuity: Both parts originate from Renesas Electronics Corporation, ensuring consistent design philosophy, quality standards, and technical support infrastructure.

2. Product Status: The substitute maintains Active product status with current manufacturing and distribution support, eliminating supply chain risk associated with obsolete components.

3. Regulatory Compliance: The substitute carries REACH Unaffected status and EAR99 ECCN classification, confirming compliance with international trade and environmental regulations.

4. Packaging Specification: The substitute is supplied in Tape & Reel (TR) format with 20QFN package configuration, enabling automated assembly processes.

5. Moisture Sensitivity: MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Why is the 252M-64LFT classified as obsolete?

A: The 252M-64LFT has reached end-of-life status within Renesas Electronics Corporation's product portfolio. Obsolete classification indicates that the manufacturer no longer produces this component and will not provide ongoing technical support or inventory replenishment.

Q: Is the 5L35021B-000NDGI8 a direct pin-for-pin replacement?

A: Substitution compatibility is determined by functional equivalence within the Clock/Timing category and manufacturer alignment. Pin configuration details are not provided in the available technical parameters. Circuit-level integration requirements must be evaluated against specific application schematics.

Q: What does the 20QFN package designation mean?

A: QFN (Quad Flat No-Lead) is a surface-mount package format. The "20" indicates 20 lead positions. This package type is standard for modern integrated circuits and supports automated pick-and-place assembly.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 represents the lowest moisture sensitivity level. Components with this rating do not require special moisture-controlled storage or baking procedures prior to soldering, simplifying manufacturing logistics.

Q: Are there any export restrictions on the 5L35021B-000NDGI8?

A: The part carries EAR99 ECCN classification, which is the most permissive export control category. This classification permits standard commercial distribution without additional export licensing requirements for most destinations.

Q: What is the difference between the base part number 5L35021 and the full part number 5L35021B-000NDGI8?

A: The base part number 5L35021 identifies the core product family. The extended suffix (B-000NDGI8) specifies particular configuration, speed grade, and packaging options within that family. The full part number ensures precise component selection.
