TAS3001CPWR Equivalent & Substitute Parts

Part Overview

The TAS3001CPWR is a 2-channel audio signal processor manufactured by Texas Instruments, housed in a 28-TSSOP surface mount package. This component is designed for digital audio interfacing applications with I2C interface support. The device operates at 3V to 3.6V supply voltage across a 0°C to 70°C temperature range and features 32-bit signal processing capabilities.

The TAS3001CPWR has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this audio signal processor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAS3001CPWR are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Audio signal processing function for digital audio interfacing applications
• 2-channel audio processing capability
• 32-bit signal resolution
• Surface mount technology
• ROHS3 compliance and REACH unaffected status
• Supply voltage compatibility within or overlapping the 3V to 3.6V range
• I2C or equivalent digital interface capability

The substitute parts listed below meet these core functional and compliance requirements. However, package differences and interface variations exist and must be evaluated against specific application constraints.

Engineering Selection Recommendations

PCM3070IRHBR (Texas Instruments)

The PCM3070IRHBR is an active product offering enhanced capabilities over the obsolete TAS3001CPWR. Both devices are manufactured by Texas Instruments and maintain ROHS3 compliance. The PCM3070IRHBR provides extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), multiple interface options (I2C, Serial, SPI™), and documented audio codec specifications including S/N ratio and dynamic range performance. The supply voltage range is broader, supporting analog supplies from 1.8V to 3.6V. The primary design consideration is package change from 28-TSSOP to 32-VQFN (5x5), which requires PCB layout modification. Moisture sensitivity increases from MSL 1 to MSL 3, requiring controlled storage conditions.

Z87L1016ASGR2961 (Zilog)

The Z87L1016ASGR2961 is an active audio processor from Zilog with 2-channel capability and matching supply voltage range (3V to 3.6V). This device maintains ROHS3 compliance and operates within a compatible temperature range (-25°C to 70°C). The interface is serial-based rather than I2C. The package is 44-LQFP, representing a significant footprint change from the 28-TSSOP original. Moisture sensitivity is MSL 3. This option is suitable for applications where serial interface compatibility exists and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the PCM3070IRHBR directly replace the TAS3001CPWR without PCB modification?

A: No. The PCM3070IRHBR uses a 32-VQFN (5x5) package compared to the 28-TSSOP package of the TAS3001CPWR. PCB layout redesign is required. Pin assignments and functionality differ and must be verified against application schematics.

Q: What is the impact of the moisture sensitivity level change from MSL 1 to MSL 3?

A: MSL 1 (Unlimited) allows indefinite shelf storage without moisture control. MSL 3 (168 Hours) requires that components be stored in controlled humidity environments and used within 168 hours of package opening. This affects supply chain handling, storage procedures, and production planning.

Q: Are all substitute parts compatible with I2C interfaces?

A: The PCM3070IRHBR supports I2C, Serial, and SPI™ interfaces, providing I2C compatibility. The Z87L1016ASGR2961 uses Serial interface only and does not support I2C. Interface compatibility must be verified against application requirements.

Q: What is the operating temperature range difference, and does it matter?

A: The TAS3001CPWR operates 0°C to 70°C. The PCM3070IRHBR extends to -40°C to 85°C, and the Z87L1016ASGR2961 operates -25°C to 70°C. Selection depends on the target application environment. Extended range provides flexibility for industrial or automotive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The TAS3001CPWR, PCM3070IRHBR, and Z87L1016ASGR2961 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the key differences in audio codec specifications between the main part and PCM3070IRHBR?

A: The PCM3070IRHBR provides documented S/N ratio (93 dB typical for ADCs, 100 dB typical for DACs) and dynamic range (90 dB typical for ADCs, 100 dB typical for DACs). The TAS3001CPWR specifications do not include these performance metrics in the provided data. The PCM3070IRHBR also includes integrated ADC and DAC functionality (2 ADCs / 2 DACs) with Sigma Delta modulation.
