Renesas 7152M-02LF Spread Spectrum Clock Generator - Equivalent & Substitute Parts

Part Overview

The Renesas 7152M-02LF is a Spread Spectrum Clock Generator IC designed for applications requiring precise clock signal generation with spread spectrum capability. This Surface Mount device operates at a maximum frequency of 134MHz and is housed in an 8-SOIC package. The part is currently in Active product status with 754 units available in stock.

Equivalent and substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing batches. The 7152M-02LF has one identified parametric equivalent that maintains core functional compatibility while offering alternative frequency specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7152M-02LF is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supply Voltage Range: 3V to 3.6V
• Operating Temperature Range: 0°C to 70°C
• Output Type: CMOS
• PLL Support: Yes
• Input Type: Clock
• Number of Circuits: 1
• Input:Output Ratio: 1:1
• Multiplier Function: Yes
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The 7152M-01LF qualifies as a parametric equivalent because it maintains all critical electrical and mechanical parameters. The primary difference is the maximum frequency specification: 67MHz versus 134MHz. This frequency variance does not affect substitution eligibility when the application circuit operates within the lower frequency range.

Engineering Selection Recommendations

Primary Part Selection (7152M-02LF): The 7152M-02LF is the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturing support. It is ROHS3 compliant and carries unlimited moisture sensitivity classification, suitable for standard industrial and commercial applications.

Substitute Part Selection (7152M-01LF): The 7152M-01LF is classified as Obsolete and should be used only when the application circuit operates exclusively within the 67MHz frequency range. While this part is currently in stock (938 units), its obsolete status indicates limited future availability. Selection of this substitute is appropriate only when frequency requirements do not exceed 67MHz and inventory constraints on the primary part necessitate alternative sourcing.

Both parts share identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification) and packaging specifications, ensuring mechanical and electrical compatibility within their respective frequency operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 7152M-01LF be used as a direct replacement for the 7152M-02LF in all applications?

A: The 7152M-01LF is a parametric equivalent only when the application circuit operates at frequencies not exceeding 67MHz. The substitute part has a maximum frequency specification of 67MHz compared to the main part's 134MHz. If your circuit requires operation above 67MHz, the 7152M-01LF is not suitable.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the 7152M-02LF and 7152M-01LF use the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints and assembly processes are identical.

Q: What is the significance of the Obsolete product status for the 7152M-01LF?

A: Obsolete status indicates that Renesas Electronics Corporation has discontinued active manufacturing and support for this part. While current inventory exists (938 units), future availability cannot be guaranteed. New designs should not incorporate obsolete parts.

Q: Do both parts require identical supply voltage?

A: Yes. Both parts operate with a supply voltage range of 3V to 3.6V. Power supply design and decoupling requirements are identical.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the 0°C to 70°C temperature range. Thermal management and derating considerations are equivalent.

Q: What does the 1:1 Input:Output Ratio mean for substitution purposes?

A: The 1:1 ratio indicates that both parts accept a clock input and generate a clock output at the same frequency (no frequency multiplication or division at the 1:1 setting). This functional characteristic is identical between the main part and substitute, ensuring compatible circuit behavior.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance certifications are identical.
