CS5361-KSZ Equivalent & Substitute Parts

Part Overview

The CS5361-KSZ is a 24-bit audio analog-to-digital converter (ADC) manufactured by Cirrus Logic Inc., designed for high-resolution audio acquisition at sampling rates up to 192 kHz. This component operates with dual supply sources (analog and digital) and supports both 3.3V and 5V supply voltages. The device is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design requirements and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5361-KSZ is determined by the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 192 kHz sampling rate
• Channel Configuration: Dual-channel audio ADC
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions
• Supply Voltage Compatibility: Support for both 3.3V and 5V supply rails
• Operating Temperature Range: -10°C to 70°C
• Compliance Standards: ROHS3 compliance, REACH unaffected status

The CS5361K-KSZ qualifies as a manufacturer-recommended substitute based on matching all critical electrical and mechanical parameters. While the data interface differs (I2S versus Serial), both implementations support the same resolution, sampling rate, channel count, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The CS5361K-KSZ is designated as the manufacturer-recommended substitute for the obsolete CS5361-KSZ. Both components maintain identical mechanical compatibility through the 24-SOIC package form factor and support equivalent electrical specifications for 24-bit, 192 kHz audio acquisition.

The primary design consideration is the data interface transition from Serial to I2S protocol. This change requires corresponding modifications to the digital signal processing interface within the host system but does not affect the analog acquisition performance or supply voltage requirements.

The CS5361K-KSZ carries active product status with current manufacturing availability, whereas the CS5361-KSZ is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and component replenishment.

Frequently Asked Questions (FAQ)

Q: Can the CS5361K-KSZ directly replace the CS5361-KSZ without circuit modifications?

A: The CS5361K-KSZ is mechanically and electrically compatible in terms of package form factor, pin count, and supply voltage requirements. However, the data interface differs: the original part uses Serial protocol while the substitute uses I2S protocol. Digital interface circuitry must be adapted accordingly.

Q: Are the supply voltage specifications identical between the two parts?

A: Both parts support dual analog and digital supply sources. The CS5361-KSZ specifies 3.3V and 5V operation, while the CS5361K-KSZ specifies 4.75V ~ 5.25V and 3.1V ~ 5.25V ranges. The CS5361K-KSZ provides tighter voltage tolerance specifications suitable for precision applications.

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

A: The CS5361-KSZ is classified as obsolete, indicating discontinued manufacturing and limited component availability. The CS5361K-KSZ maintains active product status with current production and established supply chains, making it the appropriate choice for new designs and ongoing procurement.

Q: Do both parts maintain the same operating temperature range?

A: Yes, both the CS5361-KSZ and CS5361K-KSZ operate across the -10°C to 70°C temperature range.

Q: Are there compliance or certification differences between the parts?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance or certification differences exist between the two parts.
