Substitute Part Grouping Explanation

Substitute parts for the CS4352-CZZR are identified based on the following critical parameters that determine functional equivalence:

• Type and Function: Audio DAC with 2-channel output
• Resolution: 24-bit digital resolution
• Sampling Rate: 192 kHz support
• Data Interface: SPI compatibility (primary control interface)
• Package: 20-TSSOP form factor for direct PCB replacement
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Surface mount technology

The WM8523GEDT/R meets all core substitution criteria while offering enhanced features including dual interface support (I2C and SPI) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The WM8523GEDT/R is the qualified substitute for the obsolete CS4352-CZZR based on the following engineering criteria:

Functional Equivalence: Both components share identical core audio DAC specifications—24-bit resolution, 2-channel output, 192 kHz sampling rate, and 20-TSSOP packaging. The identical package footprint enables direct PCB replacement without layout modifications.

Interface Compatibility: The WM8523GEDT/R supports both I2C and SPI interfaces, providing backward compatibility with existing SPI-based designs while offering additional control flexibility. Designs utilizing only SPI control require no firmware or hardware changes.

Product Status and Supply: The WM8523GEDT/R maintains active product status with confirmed inventory availability (9450 pcs), ensuring long-term supply chain reliability compared to the obsolete CS4352-CZZR.

Compliance and Certifications: The WM8523GEDT/R is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Operating Temperature Range: Both components operate across the identical -40°C to 85°C temperature range, ensuring thermal compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the WM8523GEDT/R directly replace the CS4352-CZZR on existing PCBs?

A: Yes. Both components use the 20-TSSOP package with identical pinout and footprint dimensions (0.173", 4.40mm width). Direct PCB replacement is possible without layout modifications.

Q: What is the primary difference between these two components?

A: The WM8523GEDT/R is the active successor to the obsolete CS4352-CZZR. Both share identical audio DAC specifications (24-bit, 2-channel, 192 kHz). The WM8523GEDT/R adds I2C interface support alongside SPI, operates from a single supply voltage (2.97V ~ 3.63V), and maintains ROHS3 compliance.

Q: Are there any interface compatibility concerns when substituting?

A: No. The WM8523GEDT/R supports SPI operation identical to the CS4352-CZZR. Existing SPI control firmware and hardware require no modification. The additional I2C interface is optional and does not affect SPI-based designs.

Q: What are the voltage supply differences?

A: The CS4352-CZZR requires separate analog and digital supply sources. The WM8523GEDT/R operates from a single supply voltage between 2.97V and 3.63V. Design modifications to power distribution may be required during substitution.

Q: Are there moisture sensitivity considerations?

A: The CS4352-CZZR has MSL 2 (1 Year storage), while the WM8523GEDT/R has MSL 3 (168 Hours storage). The WM8523GEDT/R requires more stringent moisture control during storage and handling. Standard ESD and moisture management practices for surface mount components apply.

Q: Is the WM8523GEDT/R available in the same packaging options?

A: The WM8523GEDT/R is available in Cut Tape (CT) and Digi-Reel® packaging formats. Confirm packaging requirements with your procurement specifications.
