Renesas 252PMLFT Clock/Frequency Synthesizer Equivalent & Substitute Parts

Part Overview

The Renesas 252PMLFT is a Clock/Frequency Synthesizer with Fanout Distribution and Spread Spectrum Clock Generator functionality, designed for 200MHz maximum frequency operation. This IC operates as a 1:2 input-to-output ratio device with integrated PLL and bypass capability, supporting both clock and crystal inputs with CMOS output configuration.

The 252PMLFT carries an Obsolete product status. Identifying equivalent and substitute parts is essential for system redesign, production continuation, and long-term supply chain management when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 252PMLFT is determined by the following critical parameters:

• Manufacturer: Renesas Electronics Corporation (same manufacturer ensures design continuity and support)
• Functional Type: Clock/Frequency Synthesizer with PLL and Bypass capability
• Maximum Frequency: 200MHz operation capability
• Input/Output Configuration: Clock and Crystal input support with CMOS output
• Supply Voltage Range: 3.135V ~ 3.465V compatibility
• Operating Temperature Range: 0°C ~ 70°C
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Moisture Sensitivity: MSL 1 (Unlimited)

The identified substitute part, 5L35021B-000NDGI8, is manufactured by Renesas Electronics Corporation and maintains functional equivalence within the Clock/Timing category. While packaging differs (20QFN vs. 8-SOIC), the electrical specifications and compliance certifications align with substitution requirements.

Parameter Comparison

Engineering Selection Recommendations

The 5L35021B-000NDGI8 is classified as an Active product from Renesas Electronics Corporation, providing long-term availability and manufacturing support compared to the Obsolete status of the 252PMLFT. Both parts maintain identical compliance certifications (REACH Unaffected, EAR99 classification) and moisture sensitivity ratings (MSL 1).

Selection of the substitute part requires PCB redesign due to package change from 8-SOIC to 20QFN. This footprint modification necessitates layout adjustments and electrical validation to confirm functional compatibility within the target application. Both parts originate from the same manufacturer, supporting design continuity and technical documentation alignment.

Frequently Asked Questions (FAQ)

Q: Can the 5L35021B-000NDGI8 directly replace the 252PMLFT without PCB modifications?

A: No. The package change from 8-SOIC to 20QFN requires PCB footprint redesign. Pin configuration and electrical connectivity must be validated against application schematics before implementation.

Q: What is the primary reason for seeking a substitute for the 252PMLFT?

A: The 252PMLFT carries Obsolete product status. The 5L35021B-000NDGI8 is an Active product from the same manufacturer, ensuring continued availability and manufacturing support.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both parts maintain REACH Unaffected status, EAR99 classification, and MSL 1 (Unlimited) moisture sensitivity ratings. RoHS3 compliance is confirmed for the 252PMLFT; substitute part compliance documentation should be verified through Renesas technical resources.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Functional type (Clock/Frequency Synthesizer), maximum frequency (200MHz), input configuration (Clock/Crystal), output type (CMOS), supply voltage range (3.135V ~ 3.465V), and operating temperature range (0°C ~ 70°C) are the primary criteria.

Q: Is the substitute part available in the same packaging as the original?

A: No. The 252PMLFT uses 8-SOIC packaging, while the 5L35021B-000NDGI8 uses 20QFN packaging. This difference requires circuit board redesign and layout modifications.
