Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS8415A-CZZ is determined by the following critical parameters:

• Functional Compatibility: The substitute must support audio receiver or transceiver functionality for digital audio interfacing
• Channel Configuration: Minimum 7-channel capability required
• Interface Protocol: I2C and/or SPI support for control and data communication
• Supply Voltage Range: Must operate within or encompass the 3.3V to 5V range
• Operating Temperature Range: Must support the required thermal operating window
• Audio Sampling Rate: Must support frequencies within or exceeding the 8kHz to 96kHz specification
• Package Compatibility: Surface mount package with compatible pinout and form factor
• Regulatory Compliance: RoHS and REACH compliance status

The WM8805GEDS/V qualifies as a substitute based on these parameters, though with noted differences in channel count, interface protocol, and performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The WM8805GEDS/V presents a viable substitute path for the obsolete CS8415A-CZZ based on the following factors:

Compliance Status: Both components maintain RoHS compliance with REACH unaffected status. The WM8805GEDS/V carries ROHS3 certification, meeting current regulatory requirements.

Product Lifecycle: The WM8805GEDS/V is classified as Last Time Buy, providing a defined procurement window before end-of-life. This status is preferable to the obsolete classification of the CS8415A-CZZ.

Functional Capability: The WM8805GEDS/V provides enhanced channel capacity (8 channels versus 7) and extended audio sampling rate support (32kHz to 192kHz versus 8kHz to 96kHz), offering performance headroom for digital audio applications.

Design Considerations: The supply voltage range of the WM8805GEDS/V (2.7V to 3.6V) is narrower than the CS8415A-CZZ (3.3V to 5V). System designs operating at 5V supply voltage require voltage regulation or level shifting. The interface protocol differs (I2S versus I2C/SPI), necessitating firmware and control circuit modifications. Package dimensions differ slightly (28-SSOP versus 28-TSSOP), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can the WM8805GEDS/V directly replace the CS8415A-CZZ without circuit modifications?

A: Direct pin-for-pin replacement is not possible. The interface protocols differ (I2S versus I2C/SPI), and the supply voltage range is narrower. Control firmware and signal routing require redesign.

Q: What is the primary reason for substitution?

A: The CS8415A-CZZ is classified as obsolete. The WM8805GEDS/V, while Last Time Buy status, provides a defined procurement window and extended product support.

Q: Are both components RoHS compliant?

A: Yes. The CS8415A-CZZ is RoHS Compliant, and the WM8805GEDS/V is ROHS3 Compliant. Both maintain REACH unaffected status.

Q: What are the key parameter differences affecting substitution?

A: Supply voltage range (3.3V-5V versus 2.7V-3.6V), interface protocol (I2C/SPI versus I2S), channel count (7 versus 8), audio sampling rates (8kHz-96kHz versus 32kHz-192kHz), and package dimensions (28-TSSOP versus 28-SSOP).

Q: Is the WM8805GEDS/V suitable for all applications using the CS8415A-CZZ?

A: Suitability depends on specific application requirements. The narrower supply voltage range and different interface protocol require system-level evaluation. The enhanced audio sampling rate capability may benefit professional audio applications.

Q: What is the moisture sensitivity level for both components?

A: Both the CS8415A-CZZ and WM8805GEDS/V carry MSL Rating 3 (168 Hours), indicating identical moisture handling requirements during storage and assembly.
