Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5361-DZZR is determined by the following critical parameters that must remain consistent:

• 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: -40°C to 85°C
• Supply Voltage Compatibility: Devices must operate within overlapping voltage ranges
• Compliance Standards: RoHS3 compliance and MSL rating

The CS5361K-DZZR qualifies as a direct substitute based on matching all critical parameters. The primary difference is the data interface specification (I2S versus Serial) and enhanced voltage supply range flexibility, which represents a functional improvement while maintaining pin-compatible packaging and core audio ADC specifications.

Parameter Comparison

Engineering Selection Recommendations

The CS5361K-DZZR is the manufacturer-recommended substitute for the obsolete CS5361-DZZR. Both devices maintain identical physical packaging, pin count, and core audio ADC specifications (24-bit resolution, 192 kHz sampling rate, 2-channel configuration). The CS5361K-DZZR offers the advantage of active product status, ensuring continued availability and manufacturing support.

The substitute part demonstrates full compliance with RoHS3 and REACH standards, matching the original part's regulatory requirements. Voltage supply specifications for the CS5361K-DZZR provide expanded operating ranges while maintaining compatibility with the original 3.3V and 5V supply requirements.

The data interface difference (I2S versus Serial) requires circuit-level evaluation to confirm compatibility with existing system designs. Both devices operate across the identical temperature range (-40°C to 85°C) and share equivalent moisture sensitivity classifications.

Frequently Asked Questions (FAQ)

Q: Can the CS5361K-DZZR be used as a direct pin-for-pin replacement?

A: The CS5361K-DZZR shares identical 24-TSSOP packaging and pin count with the CS5361-DZZR. However, the data interface specification differs (I2S versus Serial). Pin-for-pin compatibility requires verification that the receiving circuit supports I2S protocol. Physical package compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The CS5361-DZZR is classified as obsolete. The CS5361K-DZZR is the active equivalent from the same manufacturer, offering continued availability and manufacturing support while maintaining core audio ADC functionality.

Q: Are there voltage supply compatibility concerns?

A: The CS5361K-DZZR operates within expanded voltage ranges (4.75V ~ 5.25V and 3.1V ~ 5.25V) compared to the discrete 3.3V and 5V specifications of the original part. Systems supplying 3.3V or 5V fall within the substitute's operating range, ensuring supply voltage compatibility.

Q: Do both parts meet the same compliance standards?

A: Both the CS5361-DZZR and CS5361K-DZZR are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical (MSL 3, 168 Hours). Regulatory and environmental compliance requirements are equivalent.

Q: What is the critical difference between these parts?

A: The data interface protocol differs: the original part uses Serial interface, while the substitute uses I2S interface. Both maintain 24-bit resolution, 192 kHz sampling rate, and 2-channel configuration. Circuit design must accommodate the interface protocol difference.
