Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CS43130-CWZR are qualified based on the following critical parameters:

• 32-bit resolution
• 2-channel D/A converter configuration
• I2S digital interface
• 1.66V ~ 1.94V supply voltage range
• 42-WLCSP package compatibility
• Surface mount technology
• Sigma-Delta architecture

The CS43131-CWZR and CS43198-CWZR meet these core electrical and mechanical requirements. Both substitute parts are active products from Cirrus Logic Inc., addressing the obsolescence of the original CS43130-CWZR. The substitutes maintain functional compatibility through identical resolution, channel count, data interface, supply voltage specifications, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

Both CS43131-CWZR and CS43198-CWZR are active products suitable for replacing the obsolete CS43130-CWZR in new designs and production environments.

The CS43131-CWZR provides direct functional equivalence with identical electrical specifications and maintains the same internal reference architecture. This part is recommended for applications requiring straightforward substitution with no design modifications.

The CS43198-CWZR offers extended functionality through differential output capability and dual reference type support (external and internal). This part is suitable for designs requiring enhanced output flexibility while maintaining core 32-bit, 2-channel DAC performance and I2S interface compatibility.

Both substitute parts feature improved moisture sensitivity ratings (MSL 1 vs. MSL 3) and ROHS3 compliance, providing enhanced reliability and regulatory alignment compared to the original CS43130-CWZR.

Operating temperature ranges for both substitutes are narrower (-10°C ~ 70°C) than the original part (-50°C ~ 115°C). Applications requiring extended temperature operation must evaluate this specification difference against system requirements.

Frequently Asked Questions (FAQ)

Q: Can CS43131-CWZR and CS43198-CWZR be used interchangeably with CS43130-CWZR?

A: Both parts share identical 32-bit resolution, 2-channel configuration, I2S interface, supply voltage range, and 42-WLCSP package specifications. Pin-level compatibility and functional equivalence are established through these core parameters. The CS43198-CWZR includes additional differential output capability not present in the original part.

Q: What is the impact of the narrower operating temperature range in the substitute parts?

A: The CS43131-CWZR and CS43198-CWZR operate from -10°C to 70°C, compared to the CS43130-CWZR range of -50°C to 115°C. Applications operating outside the -10°C to 70°C window require thermal management evaluation or alternative component selection.

Q: How do the moisture sensitivity levels differ?

A: The CS43130-CWZR has MSL 3 (168-hour floor life), while both substitute parts have MSL 1 (unlimited floor life). MSL 1 provides superior moisture tolerance and reduces handling constraints during assembly and storage.

Q: What is the difference between internal and external reference types?

A: The CS43131-CWZR uses internal reference only. The CS43198-CWZR supports both external and internal reference configurations, allowing greater flexibility in circuit design and signal conditioning approaches.

Q: Are there packaging differences between these parts?

A: All three parts use the 42-WLCSP package with surface mount technology. Physical dimensions are 3.18x2.71 mm (CS43130-CWZR and CS43198-CWZR) and 2.71x3.18 mm (CS43131-CWZR), representing equivalent footprints suitable for direct PCB layout substitution.

Q: What compliance certifications apply to these parts?

A: The CS43130-CWZR is RoHS Compliant. Both CS43131-CWZR and CS43198-CWZR are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.
