Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5361-DZZ is determined by the following critical parameters:

• Resolution and Sampling Rate: Both the main part and substitute must support 24-bit resolution at 192 kHz sampling rate
• Channel Configuration: Dual-channel (2-channel) audio ADC architecture
• Package Compatibility: 24-TSSOP surface mount package with identical physical dimensions
• Operating Temperature Range: -40°C to 85°C operational window
• Supply Voltage Compatibility: Support for the required voltage supply range
• Data Interface: Serial communication protocol compatibility
• Compliance Standards: ROHS3 compliance and equivalent moisture sensitivity rating

The CS5361K-DZZ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while maintaining the same package footprint and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The CS5361K-DZZ is the manufacturer-recommended substitute for the obsolete CS5361-DZZ. Both components maintain identical mechanical compatibility through the 24-TSSOP package specification and equivalent thermal operating ranges. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts satisfy ROHS3 compliance requirements and equivalent moisture sensitivity classifications, supporting deployment in regulated environments. The voltage supply specifications of the CS5361K-DZZ provide extended operating ranges while maintaining compatibility with the original part's supply voltage requirements.

The primary design consideration involves the data interface specification: the CS5361-DZZ implements a Serial interface, while the CS5361K-DZZ implements I2S (Integrated Interchip Sound) protocol. System-level integration must account for this interface difference during component substitution.

Frequently Asked Questions (FAQ)

Q: Can the CS5361K-DZZ directly replace the CS5361-DZZ without PCB modifications?

A: The CS5361K-DZZ maintains identical package dimensions and pinout compatibility with the CS5361-DZZ, allowing direct physical replacement on the PCB. However, the data interface difference (Serial vs. I2S) requires firmware or signal processing adjustments to accommodate the protocol change.

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

A: Both parts operate with dual analog and digital supply voltages. The CS5361K-DZZ specifies 4.75V ~ 5.25V and 3.1V ~ 5.25V ranges, which encompass the 3.3V and 5V nominal supplies of the original CS5361-DZZ. Existing power distribution designs require verification to confirm compliance with the substitute part's specified voltage ranges.

Q: What is the significance of the Active product status for the CS5361K-DZZ?

A: Active product status indicates that the CS5361K-DZZ remains in current production with ongoing manufacturer support, component availability, and technical documentation updates. This contrasts with the Obsolete status of the CS5361-DZZ, which has reached end-of-life.

Q: Do both parts meet the same compliance and environmental standards?

A: Both the CS5361-DZZ and CS5361K-DZZ are ROHS3 compliant and carry identical Moisture Sensitivity Level 3 ratings (168 Hours). Both operate across the -40°C to 85°C temperature range, supporting equivalent environmental and regulatory requirements.

Q: What is the primary difference between these audio ADC variants?

A: The primary electrical difference is the data interface protocol: the CS5361-DZZ uses Serial communication, while the CS5361K-DZZ implements I2S protocol. Both maintain 24-bit resolution, 192 kHz sampling rate, and dual-channel architecture. The interface difference requires system-level protocol adaptation during substitution.
