Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5351-BZZ is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 192 kHz sampling rate
• Channel Configuration: Dual-channel (2-channel) audio conversion
• Data Interface: Serial interface for digital output
• Supply Voltage Compatibility: Operation at both 3.3V and 5V
• Package Compatibility: 24-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Thermal Operating Range: -40°C to 85°C
• Moisture Sensitivity: MSL 3 classification

The CS5351-DZZ is identified as a manufacturer-recommended substitute. This part maintains identical electrical specifications, channel count, resolution, sampling rate, data interface, supply voltage range, operating temperature, and package form factor. The primary distinction is packaging format (Tube versus unspecified for the main part) and improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The CS5351-DZZ is the manufacturer-recommended substitute for the CS5351-BZZ. Both parts are classified as obsolete products from Cirrus Logic Inc., indicating end-of-life status. The CS5351-DZZ provides identical functional and electrical performance with the added advantage of explicit RoHS3 compliance certification, which may be required for new designs or regulatory compliance in certain markets.

Selection between these parts should be based on:

• Regulatory Requirements: If RoHS3 compliance is mandated, the CS5351-DZZ is the appropriate choice.
• Inventory Availability: The CS5351-DZZ currently has higher inventory availability (2000 Pcs) compared to the CS5351-BZZ (731 Pcs).
• Packaging Format: The CS5351-DZZ is supplied in Tube packaging, which may affect handling and storage procedures.
• Long-term Viability: Both parts are obsolete; for new designs, evaluation of current-generation Cirrus Logic audio ADC solutions is recommended.

Frequently Asked Questions (FAQ)

Q: Can the CS5351-DZZ be used as a direct replacement for the CS5351-BZZ in existing designs?

A: Yes. The CS5351-DZZ is electrically and mechanically equivalent to the CS5351-BZZ. Both parts feature identical 24-bit resolution, 192 kHz sampling rate, dual-channel configuration, serial data interface, 3.3V/5V supply voltage compatibility, 24-TSSOP package dimensions, and -40°C to 85°C operating temperature range. Pin-for-pin compatibility and functional equivalence are confirmed.

Q: What is the difference between the CS5351-BZZ and CS5351-DZZ?

A: The primary differences are packaging format and compliance certification. The CS5351-DZZ is supplied in Tube packaging and carries explicit RoHS3 compliance status, whereas the CS5351-BZZ packaging format is unspecified and RoHS status is not documented. Electrical and functional specifications are identical.

Q: Are there any thermal or environmental considerations when substituting these parts?

A: Both parts operate across the identical temperature range of -40°C to 85°C and share MSL 3 (168 Hours) moisture sensitivity classification. No additional thermal or environmental considerations apply to substitution.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates that Cirrus Logic Inc. has discontinued manufacturing and support for these specific part numbers. This classification necessitates careful inventory planning and consideration of alternative current-generation audio ADC solutions for new product designs.

Q: Is the 24-TSSOP package compatible with standard surface mount assembly processes?

A: Yes. The 24-TSSOP package is a standard surface mount form factor with 0.173" (4.40mm) width, compatible with conventional pick-and-place and reflow soldering processes used in electronics manufacturing.
