Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5344-CZZ is determined by the following critical parameters:

• Resolution: 24-bit audio ADC capability
• Channel Count: Dual-channel (2-channel) configuration
• Sampling Rate: Minimum 96 kHz support
• Data Interface: Serial or I2S protocol compatibility
• Supply Voltage: Compatibility with 3.1V–5.25V range
• Operating Temperature: −40°C to +85°C range
• Package Type: Surface-mount TSSOP family
• Compliance: ROHS3 and REACH compliance

The CS5361K-DZZ qualifies as a manufacturer-recommended substitute because it maintains the core audio ADC functionality with 24-bit resolution, dual-channel architecture, and extended sampling rate capability (192 kHz). Both parts are manufactured by Cirrus Logic Inc., operate within compatible temperature ranges, and meet identical compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The CS5361K-DZZ is the manufacturer-recommended substitute for the CS5344-CZZ. Selection of this substitute is supported by the following factors:

• Product Status: The CS5361K-DZZ maintains Active product status, ensuring long-term availability and continued manufacturing support, whereas the CS5344-CZZ is in Last Time Buy status.
• Compliance Alignment: Both parts maintain ROHS3 and REACH compliance, meeting identical regulatory requirements.
• Functional Compatibility: Both components provide 24-bit, dual-channel audio ADC functionality with overlapping supply voltage ranges and identical operating temperature specifications.
• Enhanced Capability: The CS5361K-DZZ offers extended sampling rate capability (192 kHz versus 96 kHz), providing design flexibility for higher-fidelity audio applications.

Design integration requires evaluation of interface protocol differences (Serial versus I2S) and package footprint changes (10-TSSOP to 24-TSSOP).

Frequently Asked Questions (FAQ)

Q: What are the primary differences between CS5344-CZZ and CS5361K-DZZ?

A: The CS5361K-DZZ provides doubled sampling rate capability (192 kHz versus 96 kHz), uses I2S data interface instead of Serial, and is housed in a larger 24-TSSOP package (4.40mm width) compared to the 10-TSSOP package (3.00mm width) of the CS5344-CZZ. Both maintain 24-bit resolution, dual-channel configuration, and identical operating temperature range.

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

A: No. The CS5361K-DZZ uses a 24-pin TSSOP package versus the 10-pin TSSOP package of the CS5344-CZZ, requiring PCB layout redesign. Additionally, the data interface protocol differs (I2S versus Serial), necessitating firmware or signal processing modifications.

Q: Are there supply voltage compatibility concerns?

A: Both parts support the 4.75V–5.25V range. The CS5344-CZZ additionally supports 3.1V–4.6V operation, while the CS5361K-DZZ supports 3.1V–5.25V. For designs operating at 3.1V–4.6V, the CS5344-CZZ remains the only option from this substitute pair.

Q: What is the MSL (Moisture Sensitivity Level) difference?

A: The CS5344-CZZ has MSL 2 (1 Year storage), while the CS5361K-DZZ has MSL 3 (168 Hours storage). This affects component handling, storage conditions, and shelf-life management during manufacturing.

Q: Is the CS5361K-DZZ suitable for 96 kHz applications?

A: Yes. The CS5361K-DZZ supports sampling rates up to 192 kHz, which includes 96 kHz operation. However, interface protocol and package changes still require design modifications.
