CS4352-DZZ Equivalent & Substitute Parts

Part Overview

The CS4352-DZZ is a 24-bit audio digital-to-analog converter (DAC) manufactured by Cirrus Logic Inc., designed for high-fidelity audio applications with 192 kHz sampling rate capability. This component operates as a 2-channel DAC with SPI interface and dual supply voltage configuration (analog and digital). The CS4352-DZZ is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS4352-DZZ is based on the following critical parameters that must remain consistent:

• Resolution and Sampling Rate: Both substitute parts maintain 24-bit resolution and 192 kHz sampling rate, ensuring audio fidelity equivalence
• Package and Pinout: Both substitutes use the identical 20-TSSOP package, enabling direct PCB compatibility
• Number of Channels: Both substitutes provide 2-channel configuration matching the original design
• Mounting Type: Surface mount technology remains unchanged
• Data Interface Compatibility: The CS4352-DZZ uses SPI; substitute parts support both I2C and SPI, providing interface flexibility while maintaining SPI compatibility

The WM8523GEDT and WM8523GEDT/R are manufacturer-recommended equivalents from Cirrus Logic Inc., both classified as active products. The primary difference between these two substitutes is packaging format: WM8523GEDT is supplied in standard packaging, while WM8523GEDT/R is supplied in Cut Tape and Digi-Reel format with different moisture sensitivity specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Continuation:

The WM8523GEDT and WM8523GEDT/R are active, manufacturer-recommended substitutes for the obsolete CS4352-DZZ. Both parts maintain functional equivalence across all critical audio specifications: 24-bit resolution, 192 kHz sampling rate, 2-channel configuration, and 20-TSSOP package compatibility.

WM8523GEDT is suitable for applications where standard packaging and unlimited moisture sensitivity storage are acceptable. This variant provides the most flexible handling and storage conditions.

WM8523GEDT/R is specified for high-volume production environments utilizing automated tape-and-reel handling. The Cut Tape and Digi-Reel packaging format reduces component handling time in manufacturing. Moisture sensitivity level 3 (168 hours) requires adherence to standard moisture control protocols during storage and assembly.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The operating temperature range of -40°C to 85°C for substitute parts is narrower than the original CS4352-DZZ (-40°C to 105°C); applications requiring operation above 85°C require design review.

Frequently Asked Questions (FAQ)

Q: Can WM8523GEDT and WM8523GEDT/R be used interchangeably in the same application?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: WM8523GEDT uses standard packaging while WM8523GEDT/R uses Cut Tape and Digi-Reel format. Selection depends on manufacturing process requirements and inventory handling procedures.

Q: What is the impact of the narrower operating temperature range on substitution?

A: The substitute parts operate from -40°C to 85°C, compared to the original -40°C to 105°C. Applications requiring operation above 85°C cannot use these substitutes without design modification or thermal management review.

Q: Are the substitute parts pin-compatible with the CS4352-DZZ?

A: Yes. Both WM8523GEDT variants use the identical 20-TSSOP package with the same pinout, enabling direct PCB replacement without layout modifications.

Q: What is the difference between SPI-only and I2C/SPI interface support?

A: The CS4352-DZZ supports SPI interface only. The substitute parts support both I2C and SPI interfaces. Designs using SPI will function identically; the additional I2C capability provides design flexibility for new applications but does not affect existing SPI implementations.

Q: How do moisture sensitivity levels affect component handling?

A: CS4352-DZZ (MSL 2) allows 1 year of dry storage. WM8523GEDT (MSL 1) allows unlimited storage without moisture control. WM8523GEDT/R (MSL 3) requires moisture control for 168 hours after packaging opening. Select based on your manufacturing environment and storage capabilities.

Q: Are regulatory certifications equivalent between the original and substitute parts?

A: Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original part's compliance status is not specified in available documentation.
