Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8960CGEFL/RV is determined by the following critical parameters:

Functional Equivalence Criteria:

• Stereo audio codec architecture with dual ADC/DAC configuration
• 24-bit resolution capability
• Sigma Delta modulation support
• Matching signal-to-noise ratio specifications (94 dB ADC / 98 dB DAC)
• Operating temperature range: -40°C ~ 85°C
• Manufacturer: Cirrus Logic Inc.

Electrical Compatibility Criteria:

• Analog supply voltage range compatibility
• Digital supply voltage range compatibility
• Data interface support (I2C, SPI)

Physical & Compliance Criteria:

• Surface mount technology
• RoHS compliance status
• REACH compliance status
• ECCN classification (EAR99)

The WM8962BECSN/R qualifies as a direct substitute based on matching core audio specifications, identical signal-to-noise ratios, overlapping supply voltage ranges, and equivalent compliance certifications. The primary design consideration is the package transition from 32-QFN to 49-CSP, which requires PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The WM8962BECSN/R is the qualified substitute for the obsolete WM8960CGEFL/RV based on the following engineering factors:

Functional Alignment: Both components deliver identical audio codec performance with 24-bit resolution, dual ADC/DAC architecture, and matching signal-to-noise specifications. The WM8962BECSN/R maintains full compatibility with the core audio processing requirements of the original design.

Compliance & Certification: The WM8962BECSN/R holds ROHS3 compliance, representing an advancement over the RoHS Compliant status of the WM8960CGEFL/RV. Both components maintain REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory continuity.

Production Status: The WM8962BECSN/R is in active production with confirmed inventory availability (6140 units), whereas the WM8960CGEFL/RV is obsolete. This transition ensures long-term supply chain stability and component availability for future production runs.

Electrical Compatibility: Supply voltage ranges overlap sufficiently for direct substitution in most applications. The WM8962BECSN/R operates at lower analog supply voltages (1.7V ~ 2V) compared to the original (2.7V ~ 3.6V), requiring verification of power supply design compatibility.

Physical Considerations: The package transition from 32-QFN to 49-CSP necessitates PCB layout redesign. The WM8962BECSN/R footprint is larger (3.6x3.9 mm vs. 5x5 mm), but the increased pin count (49 vs. 32) provides enhanced functionality and improved signal integrity through additional ground and power distribution pins.

Frequently Asked Questions (FAQ)

Q: Can the WM8962BECSN/R be used as a direct pin-for-pin replacement?

A: No. The WM8962BECSN/R uses a 49-CSP package compared to the 32-QFN package of the WM8960CGEFL/RV. Pin assignments differ, requiring schematic and PCB layout modifications. However, the functional audio codec performance is equivalent.

Q: What are the key differences in supply voltage requirements?

A: The WM8960CGEFL/RV requires analog supply voltage of 2.7V ~ 3.6V, while the WM8962BECSN/R operates at 1.7V ~ 2V. Digital supply voltage ranges overlap (1.71V ~ 3.6V vs. 1.62V ~ 3.6V). Power supply design must be adjusted to accommodate the lower analog voltage specification of the substitute.

Q: Are there any compliance or regulatory differences?

A: Both components are RoHS compliant and REACH Unaffected. The WM8962BECSN/R carries ROHS3 certification, which represents a more recent compliance standard. Both maintain EAR99 ECCN classification. No regulatory barriers exist for substitution.

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

A: The WM8960CGEFL/RV has MSL 3 (168 hours), while the WM8962BECSN/R has MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and eliminates time-based storage constraints. The substitute offers improved handling flexibility during manufacturing and storage.

Q: Are the audio specifications identical?

A: Yes. Both components deliver 24-bit resolution, dual ADC/DAC configuration, 94 dB ADC signal-to-noise ratio, and 98 dB DAC signal-to-noise ratio. Sigma Delta modulation is supported in both designs. Audio performance is functionally equivalent.

Q: What data interfaces does the WM8962BECSN/R support?

A: The WM8962BECSN/R supports I2C and SPI interfaces for digital communication. The original WM8960CGEFL/RV data interface specification was not provided in the component documentation. Verify that your application design accommodates these interface standards.

Q: Is the WM8962BECSN/R currently available?

A: Yes. The WM8962BECSN/R is in active production status with 6140 units in stock. The WM8960CGEFL/RV is obsolete with no ongoing manufacturing. The substitute ensures component availability for new production and design revisions.
