CS4265-DNZ Equivalent & Substitute Parts

Part Overview

The CS4265-DNZ is a stereo audio interface codec manufactured by Cirrus Logic Inc., designed for 24-bit serial audio applications with 104 dB dynamic range across both ADC and DAC channels. This component operates across dual supply voltage ranges (3.13V to 5.25V for both analog and digital supplies) and is housed in a 32-QFN (5x5) surface mount package.

The CS4265-DNZ carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new procurement and ongoing system support. The part remains in stock (715 units available), but long-term availability cannot be guaranteed due to its discontinued status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS4265-DNZ is determined by the following critical parameters:

• Package Compatibility: 32-QFN (5x5) with exposed pad (32-VFQFN)
• Functional Specifications: 24-bit resolution, dual ADC/DAC configuration, serial data interface
• Dynamic Range: 104 dB minimum for both ADC and DAC channels
• Supply Voltage Ranges: 3.13V to 5.25V for analog and digital supplies
• Operating Temperature Range: -40°C to 105°C
• Mounting Type: Surface mount

The CS4265K-DNZ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share identical package geometry, pin configuration, resolution, channel count, dynamic range specifications, supply voltage ranges, and operating temperature limits. Differences in product status, moisture sensitivity level, and S/N ratio specifications do not affect functional interchangeability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The CS4265K-DNZ serves as the direct substitute for the CS4265-DNZ based on electrical and mechanical parameter equivalence. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CS4265-DNZ is classified as Obsolete, indicating end-of-life status with no further manufacturing planned. The CS4265K-DNZ carries a Not For New Designs status, indicating limited availability and restricted use in new product development. For applications requiring long-term component availability and support, evaluation of alternative codec solutions from current product lines is recommended.

The moisture sensitivity level difference (MSL 2 versus MSL 3) reflects different storage and handling requirements. MSL 3 components require more stringent moisture control during storage and assembly processes, with a maximum floor life of 168 hours compared to 1 year for MSL 2 components.

Frequently Asked Questions (FAQ)

Q: Can CS4265K-DNZ be used as a direct replacement for CS4265-DNZ in existing designs?

A: Yes. Both parts share identical package geometry (32-QFN 5x5), pin configuration, resolution (24-bit), channel configuration (2 ADC / 2 DAC), dynamic range (104 dB), supply voltage ranges (3.13V to 5.25V), and operating temperature range (-40°C to 105°C). No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: CS4265-DNZ is Obsolete (no further production), while CS4265K-DNZ is Not For New Designs (limited availability, restricted for new applications). Both statuses indicate restricted availability. Neither part is recommended for new product development.

Q: How does the moisture sensitivity level difference affect component handling?

A: CS4265-DNZ (MSL 2) allows 1 year of dry storage, while CS4265K-DNZ (MSL 3) allows only 168 hours. MSL 3 components require more frequent baking and shorter exposure times during assembly. Verify your manufacturing process can accommodate MSL 3 requirements before substitution.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both CS4265-DNZ and CS4265K-DNZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What are the key parameters that determine substitution eligibility?

A: Package type (32-QFN 5x5), resolution (24-bit), channel count (2/2 ADC/DAC), dynamic range (104 dB minimum), supply voltage ranges (3.13V to 5.25V), and operating temperature range (-40°C to 105°C) are the critical parameters. Matching these parameters ensures functional interchangeability.
