Key Parameters

Substitute Part Grouping Explanation

Substitution of the 672M-02ILFT is based on the following critical parameters:

• Functional Classification: Fanout Buffer / Clock Distribution IC
• Frequency Range: Maximum operating frequency of 135MHz or higher
• Input/Output Configuration: 1:4 distribution ratio capability
• Output Logic Family: CMOS output compatibility
• Supply Voltage Range: Support for 3.13V to 5.5V operation
• Thermal Operating Range: -40°C to 85°C minimum
• Manufacturer Continuity: Renesas Electronics Corporation

The identified substitute part 5P35023B-000NLGI8 is classified as a Clock Generator IC from the same manufacturer. While this part operates in the Clock/Timing category and maintains manufacturer continuity with Renesas Electronics Corporation, it represents a functional alternative rather than a pin-for-pin replacement due to different packaging and circuit architecture.

Parameter Comparison

Engineering Selection Recommendations

The 5P35023B-000NLGI8 is an Active product from Renesas Electronics Corporation, providing long-term availability and supply chain continuity compared to the Obsolete 672M-02ILFT. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring regulatory compliance equivalence.

The substitute part features improved moisture handling characteristics with MSL 1 (Unlimited) versus MSL 3 (168 Hours), reducing storage and handling constraints. However, the package transition from 16-SOIC to 24QFN requires PCB layout redesign and schematic modification. This substitution is suitable for new designs or system redesigns where layout flexibility exists.

For applications requiring direct form-factor compatibility without redesign, alternative 16-SOIC clock distribution solutions from Renesas or other manufacturers should be evaluated separately.

Frequently Asked Questions (FAQ)

Q: Can the 5P35023B-000NLGI8 be used as a direct replacement for the 672M-02ILFT?

A: No. While both are Renesas Clock/Timing ICs, they differ in package type (16-SOIC versus 24QFN), pin count, and internal architecture. Direct substitution requires PCB redesign and schematic modification.

Q: What are the key differences between these parts?

A: The main differences are package format (16-SOIC versus 24QFN), product status (Obsolete versus Active), and moisture sensitivity level (MSL 3 versus MSL 1). The 5P35023B-000NLGI8 offers improved availability and reduced moisture handling requirements.

Q: Are both parts RoHS compliant?

A: The 672M-02ILFT is confirmed ROHS3 Compliant. RoHS compliance status for the 5P35023B-000NLGI8 is not specified in the provided data.

Q: What is the significance of the MSL rating difference?

A: MSL 3 (168 Hours) requires component use within 168 hours of moisture exposure, while MSL 1 (Unlimited) has no time restriction. The substitute part offers greater flexibility in storage and handling procedures.

Q: Are export classifications identical?

A: Yes. Both parts are classified as EAR99 and REACH Unaffected, maintaining equivalent regulatory treatment for export and environmental compliance purposes.
