CS8415A-CSZ Equivalent & Substitute Parts

Part Overview

The CS8415A-CSZ is a 7-channel audio receiver IC manufactured by Cirrus Logic Inc., designed for digital audio interfacing applications. This component operates across a supply voltage range of 3.3V to 5V and supports audio sampling frequencies from 8kHz to 96kHz. The device is mounted in a 28-SOIC package and features I2C and SPI interface capabilities.

The CS8415A-CSZ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term product maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS8415A-CSZ is determined by the following critical parameters:

• Package Compatibility: Physical form factor must accommodate the 28-SOIC footprint or equivalent surface-mount package
• Functional Classification: Audio receiver or audio transceiver capability for digital audio interfacing
• Interface Protocol: Support for I2C, SPI, or I2S communication standards
• Supply Voltage Range: Operating voltage must overlap or encompass the 3.3V to 5V requirement
• Operating Temperature Range: Must support the -10°C to 70°C operating window
• Audio Frequency Specification: Minimum support for 8kHz to 96kHz sampling rates
• Regulatory Compliance: RoHS and REACH compliance status

Two substitute parts meet these criteria: the CS8416-CSZ (manufacturer-recommended substitute) and the WM8805GEDS/V (alternative substitute). Both are Cirrus Logic audio components with compatible package types and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

CS8416-CSZ is the manufacturer-recommended substitute for the CS8415A-CSZ. Both devices share identical package geometry (28-SOIC), matching supply voltage range (3.3V ~ 5V), and equivalent operating temperature specifications (-10°C ~ 70°C). The CS8416-CSZ provides enhanced audio frequency support (32kHz ~ 192kHz versus 8kHz ~ 96kHz) and increased channel count (8 versus 7 channels). Both components maintain RoHS3 compliance and identical moisture sensitivity ratings. This substitute requires no PCB redesign and provides direct functional replacement with expanded capability.

WM8805GEDS/V is an alternative substitute with different package geometry (28-SSOP versus 28-SOIC) and interface protocol (I2S versus I2C/SPI). This component operates at a lower supply voltage range (2.7V ~ 3.6V) and supports an extended operating temperature range (-40°C ~ 85°C). The WM8805GEDS/V is classified as Last Time Buy. Selection of this substitute requires PCB layout modification to accommodate the different package footprint and circuit redesign to implement I2S communication protocol. This option is suitable only when the lower supply voltage and extended temperature range provide specific design advantages.

Frequently Asked Questions (FAQ)

Q: Can the CS8416-CSZ directly replace the CS8415A-CSZ without PCB modification?

A: Yes. The CS8416-CSZ uses the identical 28-SOIC package footprint and pin configuration as the CS8415A-CSZ. No PCB redesign is required. Both devices support the same supply voltage range and operating temperature specifications.

Q: What are the functional differences between the CS8415A-CSZ and CS8416-CSZ?

A: The CS8416-CSZ provides 8 audio channels compared to 7 channels in the CS8415A-CSZ. The CS8416-CSZ also supports higher audio sampling frequencies (32kHz ~ 192kHz versus 8kHz ~ 96kHz). Both devices maintain I2C and SPI interface compatibility.

Q: Is the WM8805GEDS/V a direct replacement for the CS8415A-CSZ?

A: No. The WM8805GEDS/V uses a different package type (28-SSOP versus 28-SOIC), requiring PCB layout modification. The interface protocol differs (I2S versus I2C/SPI), necessitating circuit redesign. The supply voltage range is narrower (2.7V ~ 3.6V versus 3.3V ~ 5V). This substitute is suitable only when design requirements specifically accommodate these differences.

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

A: All three components (CS8415A-CSZ, CS8416-CSZ, and WM8805GEDS/V) have a Moisture Sensitivity Level (MSL) rating of 3, indicating a maximum floor life of 168 hours at 60% relative humidity and 30°C before baking is required.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CS8415A-CSZ is RoHS Compliant. Both substitute parts (CS8416-CSZ and WM8805GEDS/V) are ROHS3 Compliant. All components are REACH Unaffected.

Q: What is the product status of the substitute parts?

A: The CS8416-CSZ is classified as Obsolete. The WM8805GEDS/V is classified as Last Time Buy, indicating limited availability and imminent discontinuation.
