Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5361-KZZ is based on the following critical parameters that must remain consistent across equivalent components:

• Resolution and Sampling Rate: 24-bit resolution at 192 kHz sampling rate
• Channel Configuration: 2-channel audio ADC
• Package Compatibility: 24-TSSOP surface mount package with identical physical dimensions
• Operating Temperature Range: -10°C to 70°C
• Supply Voltage Compatibility: Dual supply capability for analog and digital domains
• Compliance Standards: ROHS3 compliance and equivalent moisture sensitivity rating

The CS5361K-KZZ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the data interface protocol (I2S versus Serial) and the active product status of the substitute, which provides ongoing manufacturer support and availability.

Parameter Comparison

Engineering Selection Recommendations

The CS5361K-KZZ is the designated manufacturer substitute for the obsolete CS5361-KZZ. Both components maintain identical mechanical compatibility through the 24-TSSOP package format and equivalent electrical specifications for resolution, sampling rate, and channel configuration. The substitute part carries active product status from Cirrus Logic Inc., ensuring continued availability and manufacturer support.

Both parts satisfy ROHS3 compliance requirements and equivalent moisture sensitivity classifications, making them suitable for applications requiring environmental and regulatory adherence. The voltage supply specifications of the substitute part provide expanded operating ranges while maintaining compatibility with the original part's supply requirements.

The primary design consideration is the data interface protocol difference: the original part uses Serial interface while the substitute employs I2S protocol. System integration must account for this interface distinction during component selection and circuit design.

Frequently Asked Questions (FAQ)

Q: Can the CS5361K-KZZ directly replace the CS5361-KZZ without circuit modifications?

A: Physical and electrical compatibility is maintained through identical package format, resolution, sampling rate, and channel configuration. However, the data interface protocol differs (Serial versus I2S), requiring interface circuit adaptation.

Q: Are the supply voltage specifications compatible between these parts?

A: Both parts support dual analog and digital supply domains. The substitute part specifies expanded voltage ranges (4.75V ~ 5.25V and 3.1V ~ 5.25V) that encompass the original part's nominal supply levels (3.3V, 5V), ensuring compatibility with existing power distribution designs.

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

A: The CS5361-KZZ is classified as obsolete, indicating discontinued manufacturing and limited availability. The CS5361K-KZZ maintains active status, providing ongoing manufacturer support, documentation updates, and reliable supply chain access.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Both parts carry identical Moisture Sensitivity Level 3 (168 Hours) ratings and ROHS3 compliance certifications, ensuring equivalent handling, storage, and environmental requirements.

Q: What is the base product number relationship?

A: The CS5361 represents the base product family. Both the CS5361-KZZ and CS5361K-KZZ derive from this common platform, with variant designations indicating specific configuration and interface differences.
