CS8416-CZZR Equivalent & Substitute Parts

Part Overview

The CS8416-CZZR 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-CZZR is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS8416-CZZR is evaluated based on 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: I2C and SPI interface support must be maintained for firmware and hardware integration compatibility.
• Operating Temperature Range: The substitute must support the same or wider operating temperature range (-10°C ~ 70°C) to ensure functional equivalence across environmental conditions.
• Supply Voltage Range: The substitute voltage specification must overlap with or encompass the main part's 3.3V ~ 5V range.
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status ensure regulatory equivalence for new designs and procurement.

The CS8416K-CZZR is identified as a manufacturer-recommended substitute. While it maintains the same package, interface protocols, operating temperature range, and regulatory compliance, it differs in channel count (1 channel versus 8 channels) and supply voltage specification (3.13V ~ 3.46V versus 3.3V ~ 5V). These differences require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The CS8416K-CZZR is an active product from the same manufacturer, offering continued availability and support compared to the obsolete CS8416-CZZR. Both devices maintain identical RoHS3 compliance and MSL ratings, ensuring regulatory and environmental handling equivalence.

The primary consideration for substitution is the reduction in channel count from 8 to 1. This difference necessitates application-specific evaluation. Systems requiring 8-channel audio reception cannot be directly substituted with a single-channel device without architectural modification.

The CS8416K-CZZR operates within a narrower supply voltage range (3.13V ~ 3.46V) compared to the main part (3.3V ~ 5V). Designs operating at the upper voltage boundary (4.5V ~ 5V) or lower boundary (3.3V) require verification of power supply specifications to ensure compatibility.

Both devices share identical operating temperature specifications, interface protocols, and package geometry, supporting direct PCB footprint compatibility when channel count and voltage requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the CS8416K-CZZR directly replace the CS8416-CZZR in existing designs?

A: Direct replacement is not possible without design modification. The CS8416K-CZZR provides 1 audio channel, while the CS8416-CZZR provides 8 channels. Applications requiring multi-channel audio reception must retain the original part or implement architectural changes to accommodate single-channel operation.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the CS8416-CZZR and CS8416K-CZZR use the 28-TSSOP package with identical dimensions (0.173", 4.40mm Width). PCB footprints are directly compatible.

Q: What is the voltage compatibility between these parts?

A: The CS8416-CZZR operates at 3.3V ~ 5V, while the CS8416K-CZZR operates at 3.13V ~ 3.46V. The CS8416K-CZZR's voltage range is narrower and does not fully encompass the main part's specification. Designs operating at 3.3V fall within both ranges. Designs operating above 3.46V or below 3.13V require voltage verification before substitution.

Q: Do both parts support the same interface protocols?

A: Yes. Both devices support I2C and SPI interfaces, ensuring firmware and hardware integration compatibility.

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

A: The CS8416-CZZR is obsolete, indicating discontinued manufacturing and limited availability. The CS8416K-CZZR is active, indicating ongoing production and supplier support. For new designs or long-term procurement, the active status of the CS8416K-CZZR provides supply chain advantages.

Q: Are the moisture sensitivity and RoHS compliance ratings equivalent?

A: Yes. Both parts are ROHS3 compliant and carry MSL rating 3 (168 Hours), ensuring equivalent regulatory compliance and moisture handling requirements.
