Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CS43130-CNZ are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• 32-bit resolution with dual D/A converters
• 40-QFN (5x5) surface mount package
• Sigma-Delta architecture
• Operating temperature range: -10°C ~ 70°C
• RoHS compliance and MSL rating

Substitution Logic:

The CS43131-CNZ qualifies as a direct substitute based on matching resolution (32-bit), converter count (2), package type (40-WFQFN), architecture (Sigma-Delta), and thermal specifications. The primary difference is output type specification (Voltage - Unbuffered vs. Analog Current and Voltage) and data interface limitation (I2S only vs. I2C and I2S). Supply voltage range differs slightly (1.66V ~ 1.94V vs. fixed 1.8V).

The CS43198-CNZ qualifies as a manufacturer-recommended substitute with identical resolution, converter count, package, and architecture. This part offers extended functionality through differential output capability and dual reference type support (External and Internal). Supply voltage specifications match the CS43131-CNZ (1.66V ~ 1.94V). Data interface is limited to I2S.

Parameter Comparison

Engineering Selection Recommendations

CS43131-CNZ: This part is suitable for applications where I2S interface is sufficient and voltage supply flexibility (1.66V ~ 1.94V range) is acceptable. The active product status ensures ongoing availability and support. ROHS3 compliance provides enhanced environmental standards compared to the obsolete main part.

CS43198-CNZ: This manufacturer-recommended substitute is the preferred choice for new designs and long-term supply assurance. Active product status guarantees continued availability. The addition of differential output capability and external reference support provides design flexibility for applications requiring these features. ROHS3 compliance and REACH unaffected status meet current regulatory requirements.

Both substitutes maintain identical package geometry, resolution, converter count, and thermal operating range, ensuring mechanical and thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can CS43131-CNZ or CS43198-CNZ be used as direct pin-for-pin replacements for CS43130-CNZ?

A: Both parts share the identical 40-WFQFN package with matching pin count and exposed pad configuration. Pin-level compatibility requires verification against specific application schematics, particularly regarding data interface requirements and reference configuration.

Q: What is the primary difference between CS43131-CNZ and CS43198-CNZ?

A: The CS43198-CNZ provides differential output capability and supports both external and internal reference types, whereas CS43131-CNZ offers only single-ended output with internal reference only. Both are limited to I2S data interface.

Q: Why does CS43130-CNZ support both I2C and I2S while the substitutes support only I2S?

A: This represents a functional difference between the obsolete part and active substitutes. Applications requiring I2C control must evaluate whether I2S-only interface compatibility is achievable within their system architecture.

Q: Are the supply voltage specifications compatible between all three parts?

A: CS43130-CNZ operates at fixed 1.8V for both analog and digital supplies. CS43131-CNZ and CS43198-CNZ accept a voltage range of 1.66V ~ 1.94V, which encompasses the 1.8V nominal specification. Designs operating at fixed 1.8V are compatible with both substitutes.

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

A: CS43130-CNZ is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. CS43131-CNZ and CS43198-CNZ are active products with ongoing production and support, ensuring supply chain continuity for new applications and existing product refreshes.

Q: Do all three parts meet current RoHS requirements?

A: CS43130-CNZ is RoHS Compliant. CS43131-CNZ and CS43198-CNZ are ROHS3 Compliant, representing the current regulatory standard. Both compliance levels are acceptable for most applications; ROHS3 represents the more current specification.
