Substitute Part Grouping Explanation
Substitution eligibility for the CS4360-KZZ is determined by strict equivalence across the following critical parameters:
- Functional Specification: 24-bit resolution, 6-channel audio DAC architecture
- Digital Interface: I2S protocol compatibility
- Sampling Rate Capability: 200 kHz minimum support
- Package Compatibility: 28-TSSOP surface mount form factor with identical pin configuration
- Voltage Supply Range: Minimum 2.25V to 5.5V operational envelope
- Manufacturer: Cirrus Logic Inc. (same product family)
- Base Product Number: CS4360 series designation
The CS4360-DZZ qualifies as a direct substitute based on matching all functional and physical parameters. Differences in operating temperature range and packaging format (Tube vs. standard) do not affect electrical substitutability for applications within the CS4360-KZZ's specified temperature range.

Engineering Selection Recommendations
The CS4360-DZZ is a direct functional equivalent to the CS4360-KZZ. Both components share identical electrical specifications, pin configuration, and package geometry. The CS4360-DZZ operates across an extended temperature range (-40°C to 85°C) compared to the CS4360-KZZ (-10°C to 70°C), providing broader environmental tolerance without compromising performance within the original part's specified operating window.
Both parts carry Obsolete product status and maintain identical regulatory compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001). Selection between these variants should be based on application-specific temperature requirements and packaging format availability (Tube packaging for CS4360-DZZ).
Frequently Asked Questions (FAQ)
Q: Can the CS4360-DZZ replace the CS4360-KZZ in existing designs?
A: Yes. The CS4360-DZZ is electrically and mechanically equivalent. Both components feature identical 24-bit resolution, 6-channel architecture, I2S interface, 200 kHz sampling rate capability, and 28-TSSOP package geometry. Pin-for-pin compatibility is maintained.
Q: What is the difference between CS4360-KZZ and CS4360-DZZ?
A: The primary differences are operating temperature range (CS4360-KZZ: -10°C to 70°C; CS4360-DZZ: -40°C to 85°C) and packaging format. The CS4360-DZZ is supplied in Tube packaging. All electrical specifications and functional parameters are identical.
Q: Are there any supply voltage compatibility concerns?
A: No. Both parts operate across the identical voltage supply range of 2.25V to 5.5V, supporting both analog and digital supply configurations.
Q: What is the significance of the 28-TSSOP package specification?
A: The 28-TSSOP (Thin Shrink Small Outline Package) is a surface mount package with 0.173" width and 4.40mm body width. This specification ensures mechanical compatibility with existing PCB layouts and assembly equipment. Both substitute parts maintain this identical package geometry.
Q: Does the extended temperature range of CS4360-DZZ affect performance?
A: The CS4360-DZZ's extended operating range (-40°C to 85°C) does not degrade performance within the CS4360-KZZ's original specification window (-10°C to 70°C). Applications operating within the original temperature range experience no functional differences.
Q: Are regulatory certifications identical between these parts?
A: Yes. Both the CS4360-KZZ and CS4360-DZZ carry identical regulatory status: REACH Unaffected, ECCN EAR99, and HTSUS classification 8542.39.0001.
