Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PL602-03SC-R is determined by the following critical parameters:

Package Compatibility: The 8-SOIC (0.154", 3.90mm Width) surface mount package is the primary mechanical constraint. Substitute parts must use identical packaging to ensure PCB layout compatibility without redesign.

Electrical Interface: Both input and output configurations must support CMOS signaling. The main part accepts crystal input; substitutes may accept alternative clock input types provided output remains CMOS-compatible.

Frequency Range: The maximum operating frequency of 100MHz establishes the baseline performance requirement. Substitute parts with equal or higher maximum frequency ratings satisfy this criterion.

Supply Voltage Compatibility: Operating voltage ranges must overlap with or encompass the original 2.97V to 3.63V specification to ensure reliable operation in existing power distribution networks.

Temperature Range: The 0°C to 70°C operating temperature range must be met or exceeded by substitute components.

PLL Functionality: The presence of an integrated Phase-Locked Loop is a functional requirement for clock generation and frequency synthesis.

The identified substitute part 7152M-02LF meets all critical substitution criteria within these parameters.

Engineering Selection Recommendations

The 7152M-02LF from Renesas Electronics Corporation is the qualified substitute for the obsolete PL602-03SC-R. Selection is based on the following engineering criteria:

Package Equivalence: Both components utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package, eliminating PCB redesign requirements.

Electrical Compatibility: The substitute maintains identical CMOS output configuration, 1:1 input-to-output ratio, and single-circuit architecture. Supply voltage ranges overlap within the 3V to 3.6V window, ensuring compatibility with existing power supplies.

Performance Margin: The 7152M-02LF maximum frequency of 134MHz exceeds the original 100MHz specification, providing operational headroom for clock generation applications.

Compliance Status: Both components maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring environmental and regulatory compatibility.

Product Availability: The substitute part maintains Active product status with documented inventory availability, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 7152M-02LF directly replace the PL602-03SC-R without PCB modifications?

A: Yes. Both components use the 8-SOIC (0.154", 3.90mm Width) package with identical pin spacing and surface mount configuration. No PCB layout changes are required for mechanical and electrical integration.

Q: What is the primary difference between these two clock buffer ICs?

A: The 7152M-02LF is a Spread Spectrum Clock Generator with a maximum frequency of 134MHz, compared to the PL602-03SC-R standard clock buffer at 100MHz. Both maintain identical package, output type, and operating temperature specifications.

Q: Are the input signal requirements compatible between these parts?

A: The PL602-03SC-R accepts crystal input, while the 7152M-02LF accepts clock input. Both deliver CMOS output. System design must verify that the clock input source for the 7152M-02LF is available in the application circuit.

Q: Do supply voltage ranges present any compatibility issues?

A: The supply voltage ranges are compatible within the overlapping window of 3V to 3.6V. The PL602-03SC-R operates from 2.97V to 3.63V, while the 7152M-02LF operates from 3V to 3.6V. Verify that the system power supply operates within the 3V to 3.6V range for guaranteed compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both the PL602-03SC-R and 7152M-02LF are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), meeting environmental and regulatory requirements.

Q: What is the significance of the 134MHz maximum frequency in the substitute part?

A: The higher frequency rating of the 7152M-02LF provides operational margin above the original 100MHz specification. This allows the substitute to function reliably in applications requiring the original 100MHz performance without frequency derating.
