601M-02ILFT Clock/Frequency Synthesizer Equivalent & Substitute Parts

Part Overview

The 601M-02ILFT is a Clock/Frequency Synthesizer and Clock Generator IC manufactured by Renesas Electronics Corporation, designed for 170MHz maximum frequency operation in 16-SOIC surface mount packaging. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and production continuity. Substitute parts must maintain compatibility across electrical specifications, output characteristics, and physical form factors to ensure seamless integration into existing or redesigned applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 601M-02ILFT is determined by the following critical parameters:

• Functional Type: Clock/Frequency Synthesizer with integrated PLL and divider/multiplier capability
• Output Specification: CMOS output logic
• Input Compatibility: Clock or Crystal input support
• Frequency Range: Maximum operating frequency of 170MHz or higher
• Supply Voltage: 3V to 5.5V operating range
• Temperature Range: -40°C to 85°C minimum operating window
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

The substitute part 5P35023B-000NLGI8 maintains functional equivalence through matching clock generation architecture, PLL integration, and regulatory compliance. While packaging differs (24-QFN versus 16-SOIC), the electrical specifications and performance characteristics align with the original component's operational requirements.

Engineering Selection Recommendations

The 5P35023B-000NLGI8 is designated as the manufacturer-recommended substitute for the obsolete 601M-02ILFT. Selection of this alternative is supported by:

• Active Product Status: The substitute maintains current production and availability through Renesas Electronics Corporation, ensuring long-term supply chain reliability compared to the obsolete original component.
• Regulatory Compliance: Both components maintain REACH unaffected status and equivalent compliance posture for industrial and commercial applications.
• Moisture Sensitivity Improvement: The substitute features MSL 1 (Unlimited) versus MSL 3 (168 Hours), providing enhanced reliability in storage and handling environments with reduced moisture sensitivity constraints.
• Manufacturer Continuity: Both components originate from Renesas Electronics Corporation, ensuring design consistency and technical support alignment.

Frequently Asked Questions (FAQ)

Q: Can the 5P35023B-000NLGI8 directly replace the 601M-02ILFT in existing PCB designs?

A: Direct PCB replacement is not possible due to package differences. The 601M-02ILFT uses 16-SOIC (0.154", 3.90mm Width) packaging, while the 5P35023B-000NLGI8 uses 24-QFN packaging. PCB layout redesign and footprint modification are required. Electrical compatibility must be verified against detailed datasheets for both components.

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

A: Substitution compatibility is determined by matching clock generation functionality, PLL integration, CMOS output logic, supply voltage range (3V to 5.5V), operating temperature range (-40°C to 85°C), and maximum frequency capability (170MHz or higher). Input type (Clock or Crystal) must also align with system requirements.

Q: Why is the substitute part's MSL rating lower (MSL 1 versus MSL 3)?

A: MSL 1 (Unlimited) indicates superior moisture resistance compared to MSL 3 (168 Hours). This represents an improvement in component reliability and reduces handling constraints during storage and assembly processes.

Q: Is the substitute part currently available for procurement?

A: Yes. The 5P35023B-000NLGI8 maintains Active product status with current manufacturing and distribution through Renesas Electronics Corporation and authorized distributors, unlike the obsolete 601M-02ILFT.

Q: What documentation is required before implementing the substitute part?

A: Complete electrical datasheets for both the 601M-02ILFT and 5P35023B-000NLGI8 must be reviewed to confirm functional equivalence across all operating parameters, pin configuration, and application-specific requirements. Package footprint and PCB layout modifications must be validated through design review and prototype testing.
