Key Parameters

Substitute Part Grouping Explanation

Substitution of the WM8962ECSN/R is determined by the following critical parameters:

• Stereo Audio Codec Functionality: Both main and substitute parts must provide dual ADC and dual DAC channels for stereo audio processing
• Data Interface Compatibility: I2C and SPI control interfaces are required for system integration
• Resolution and Signal Quality: Minimum 24-bit resolution with comparable signal-to-noise ratios
• Supply Voltage Ranges: Analog and digital supply voltage compatibility within system design constraints
• Operating Temperature Range: -40°C to 85°C industrial temperature specification
• Surface Mount Packaging: Both parts utilize surface mount technology for PCB integration
• Regulatory Compliance: RoHS and REACH compliance status for manufacturing and distribution

The TLV320AIC3262IYZFR from Texas Instruments meets these substitution criteria while offering enhanced specifications in resolution (32-bit) and signal-to-noise performance.

Parameter Comparison

Engineering Selection Recommendations

The TLV320AIC3262IYZFR is suitable as a substitute for the obsolete WM8962ECSN/R based on the following factors:

• Active Product Status: The TLV320AIC3262IYZFR maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components meet RoHS and REACH compliance requirements, with the substitute offering ROHS3 certification
• Functional Equivalence: Dual stereo audio codec architecture with I2C and SPI interfaces provides direct functional compatibility
• Enhanced Specifications: The substitute offers 32-bit resolution and superior DAC signal-to-noise ratio (101 dB vs. 98 dB), providing performance headroom
• Temperature Range Alignment: Identical -40°C to 85°C operating range supports industrial applications
• Package Consideration: The TLV320AIC3262IYZFR uses an 81-pin DSBGA package versus the 49-pin WLCSP of the original part, requiring PCB layout modification

Frequently Asked Questions (FAQ)

Q: Can the TLV320AIC3262IYZFR directly replace the WM8962ECSN/R without firmware changes?

A: Both components support I2C and SPI control interfaces with identical operating temperature ranges. However, register maps and control sequences differ between manufacturers. Firmware modifications are required to accommodate the Texas Instruments device architecture.

Q: What are the package compatibility implications?

A: The WM8962ECSN/R uses a 49-pin WLCSP (4.69x3.98 mm) package, while the TLV320AIC3262IYZFR uses an 81-pin DSBGA (5x5 mm) package. PCB redesign is necessary to accommodate the larger footprint and increased pin count.

Q: Are the supply voltage ranges compatible with existing power distribution networks?

A: The TLV320AIC3262IYZFR operates at lower minimum supply voltages (1.5V analog, 1.26V digital) compared to the WM8962ECSN/R (1.7V analog, 1.62V digital). Existing power supplies designed for the original part will support the substitute. Verify that system regulators can maintain stable output within the substitute's specified ranges.

Q: How do the audio performance specifications compare?

A: The TLV320AIC3262IYZFR provides superior DAC signal-to-noise ratio (101 dB vs. 98 dB) and higher resolution (32-bit vs. 24-bit). ADC signal-to-noise performance is comparable (93 dB vs. 94 dB). Both components employ Sigma-Delta conversion architecture.

Q: What is the inventory status for each component?

A: The WM8962ECSN/R has 4,453 pieces available as new original stock. The TLV320AIC3262IYZFR has 1,341 pieces available as new original stock in tape and reel packaging.
