CS8416-DZZ Equivalent & Substitute Parts

Part Overview

The CS8416-DZZ is an audio receiver IC manufactured by Cirrus Logic Inc., designed for digital audio interfacing applications. This 8-channel audio receiver operates across a supply voltage range of 3.3V to 5V and supports sampling frequencies from 32kHz to 192kHz. The device is housed in a 28-TSSOP surface mount package and features I2C and SPI interface options.

The CS8416-DZZ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS8416-DZZ is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 28-TSSOP surface mount package to ensure PCB layout compatibility without redesign.
• Interface Protocol: Both parts must support I2C and SPI interfaces to maintain firmware and hardware communication compatibility.
• Operating Temperature Range: The substitute must cover the full operating temperature range of -40°C to 85°C.
• Compliance Standards: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity ratings.
• Manufacturer: Parts from Cirrus Logic Inc. ensure design continuity and technical support consistency.

The CS8416K-DZZ qualifies as a manufacturer-recommended substitute based on these parameters. However, differences in channel count, supply voltage range, and product status require careful evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The CS8416K-DZZ is the manufacturer-recommended substitute for the CS8416-DZZ. The primary advantage of this substitute is its active product status, ensuring ongoing availability and technical support from Cirrus Logic Inc.

Both parts maintain identical compliance certifications: ROHS3 compliance, equivalent moisture sensitivity levels (MSL 3, 168 Hours), and identical REACH and ECCN classifications. Both are housed in the same 28-TSSOP package with matching physical dimensions, supporting direct PCB compatibility.

The substitute maintains the same operating temperature range (-40°C to 85°C) and identical interface protocols (I2C and SPI), ensuring firmware compatibility.

Critical differences exist in channel count and supply voltage range. The CS8416K-DZZ operates as a single-channel receiver with a narrower supply voltage window (3.13V to 3.46V) compared to the main part's 8-channel configuration and broader supply range (3.3V to 5V). Applications requiring 8-channel audio reception or operating outside the 3.13V to 3.46V supply window must evaluate alternative solutions or design modifications.

Frequently Asked Questions (FAQ)

Q: Can the CS8416K-DZZ be used as a direct replacement for the CS8416-DZZ?

A: The CS8416K-DZZ shares the same package, interface protocols, and operating temperature range. However, it operates as a single-channel receiver versus the 8-channel configuration of the main part, and its supply voltage range (3.13V to 3.46V) is narrower. Direct substitution is possible only if your application requires single-channel operation and operates within the specified supply voltage window.

Q: What is the significance of the product status difference?

A: The CS8416-DZZ is classified as obsolete, indicating discontinued manufacturing and limited future availability. The CS8416K-DZZ maintains active product status, ensuring continued manufacturing, inventory availability, and technical support from Cirrus Logic Inc.

Q: Are there any PCB layout considerations when substituting these parts?

A: Both parts use the identical 28-TSSOP package with matching pin configurations and physical dimensions. No PCB layout modifications are required for package compatibility. However, the reduced channel count of the substitute may require firmware or signal routing adjustments depending on your application architecture.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the CS8416-DZZ and CS8416K-DZZ are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8542.39.0001) codes. Both maintain identical moisture sensitivity levels (MSL 3, 168 Hours).

Q: What supply voltage considerations apply to substitution?

A: The main part operates across 3.3V to 5V, while the substitute operates across 3.13V to 3.46V. If your design operates at 5V or below 3.13V, the substitute cannot be used without power supply modifications. Verify your application's supply voltage requirements before selecting the substitute.
