WM8962ECS/R Equivalent & Substitute Parts

Part Overview

The WM8962ECS/R is a stereo audio codec interface manufactured by Cirrus Logic Inc., designed for applications requiring high-fidelity audio processing with dual ADC/DAC channels. This component integrates 24-bit resolution audio conversion with I2C and SPI digital interfaces in a compact 49-WLCSP package. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, redesigns, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8962ECS/R is determined by the following critical parameters:

• Stereo Audio Codec Architecture: Both ADC and DAC channels must support dual-channel stereo processing
• Resolution Compatibility: Minimum 24-bit resolution to maintain audio fidelity equivalent to the original design
• Digital Interface Support: I2C and/or SPI compatibility for system integration
• Dual ADC/DAC Configuration: 2 ADCs and 2 DACs required for stereo audio processing
• Supply Voltage Ranges: Analog and digital supply voltages must accommodate system power architecture
• Operating Temperature Range: -40°C to 85°C industrial temperature specification
• Surface Mount Packaging: BGA-based packages suitable for high-density PCB layouts
• Moisture Sensitivity: MSL 1 classification for unlimited shelf life

Two substitute parts meet these criteria:

MAX98090AEWJ+T (Analog Devices Inc./Maxim Integrated): Active product with 24-bit stereo audio codec, I2C interface, 2/2 ADC/DAC configuration, and compatible supply voltage ranges.

TLV320AIC3262IYZFR (Texas Instruments): Active product with 32-bit stereo audio codec, I2C/SPI interface, 2/2 ADC/DAC configuration, and compatible supply voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

MAX98090AEWJ+T is suitable for applications requiring direct 24-bit resolution equivalence with the WM8962ECS/R. This part maintains identical bit resolution and dual ADC/DAC architecture. The product is active with ROHS3 compliance and unlimited moisture sensitivity rating. The I2C interface is supported; however, SPI interface availability is limited compared to the original design. Supply voltage ranges are broader, offering greater flexibility in power architecture implementation.

TLV320AIC3262IYZFR provides enhanced resolution at 32-bit with maintained dual ADC/DAC configuration and dual interface support (I2C and SPI). This part is active with ROHS3 compliance and unlimited moisture sensitivity rating. The 32-bit resolution exceeds the original 24-bit specification, providing additional audio processing headroom. Package dimensions differ (81-DSBGA 5x5 versus 49-WLCSP 4.69x3.98), requiring PCB layout modifications. Supply voltage ranges are narrower and require careful system power design validation.

Both substitute parts are active products with current manufacturing support, REACH compliance, and MSL 1 classification. Selection between these alternatives depends on interface requirements (SPI necessity), resolution requirements (24-bit versus 32-bit), and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can MAX98090AEWJ+T directly replace WM8962ECS/R in existing designs?

A: MAX98090AEWJ+T maintains 24-bit resolution and dual ADC/DAC configuration. The primary design consideration is the absence of SPI interface support; if the original design uses SPI exclusively, alternative solutions must be evaluated. I2C interface is fully supported. Supply voltage ranges are broader, potentially simplifying power supply design.

Q: What are the package differences between substitute parts?

A: WM8962ECS/R uses 49-WLCSP (4.69x3.98mm). MAX98090AEWJ+T uses 49-WLP (3.15x3.15mm), offering similar footprint compatibility. TLV320AIC3262IYZFR uses 81-DSBGA (5x5mm), requiring significant PCB layout redesign due to increased pin count and package size.

Q: Does TLV320AIC3262IYZFR's 32-bit resolution provide backward compatibility?

A: 32-bit resolution is a superset of 24-bit audio processing. Systems designed for 24-bit operation can utilize 32-bit codecs; however, firmware and DSP configuration must be updated to accommodate the higher resolution. This requires software validation and testing.

Q: Are both substitute parts suitable for industrial temperature applications?

A: Both MAX98090AEWJ+T and TLV320AIC3262IYZFR support the -40°C to 85°C operating temperature range, meeting industrial specifications equivalent to the WM8962ECS/R.

Q: What compliance certifications apply to substitute parts?

A: Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original WM8962ECS/R compliance status is not specified in available documentation.

Q: Which substitute part requires fewer design modifications?

A: MAX98090AEWJ+T requires minimal design modifications due to similar package footprint (49-pin BGA) and identical 24-bit resolution. TLV320AIC3262IYZFR requires PCB layout redesign due to increased pin count (81 pins) and package size (5x5mm), but provides enhanced resolution and dual interface support.
