TAS3002PFB Equivalent & Substitute Parts

Part Overview

The TAS3002PFB is a 2-channel audio signal processor manufactured by Texas Instruments, housed in a 48-TQFP (7x7) surface mount package. This component is designed for digital audio interfacing applications and operates across a 3V to 3.6V supply voltage range with an operating temperature range of 0°C to 70°C. The device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS3002PFB is determined by the following critical parameters:

• Functional Category: Audio signal processing or audio codec functionality
• Channel Configuration: 2-channel audio capability
• Interface Protocol: I2C control interface compatibility
• Supply Voltage Range: Overlap with 3V to 3.6V operating window
• Mounting Technology: Surface mount configuration
• Regulatory Compliance: ROHS3 compliance status

The identified substitute parts meet these core criteria while accommodating variations in package form factor, resolution specifications, and extended operating temperature ranges where applicable.

Parameter Comparison

Engineering Selection Recommendations

PCM3070IRHBT is the manufacturer-recommended substitute for the TAS3002PFB. This Texas Instruments component maintains active product status and provides enhanced specifications including 32-bit resolution, dual ADC/DAC configuration, and extended operating temperature range (-40°C to 85°C). The device supports multiple interface protocols (I2C, Serial, SPI) and operates across a broader supply voltage range. ROHS3 compliance and EAR99 classification align with the original part's regulatory requirements.

Z87L1016ASGR2961 represents an alternative from Zilog with active product status. This 2-channel audio processor maintains compatibility with the 3V to 3.6V supply voltage window and operates within an extended temperature range (-25°C to 70°C). Serial interface configuration and ROHS3 compliance support legacy system requirements, though this option provides a different manufacturer ecosystem.

Both substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete TAS3002PFB.

Frequently Asked Questions (FAQ)

Q: Why is the TAS3002PFB classified as obsolete? A: The TAS3002PFB has reached end-of-life status with Texas Instruments. Existing inventory remains available, but new production has ceased. Substitute parts ensure continued system support and future design flexibility.

Q: Can the PCM3070IRHBT directly replace the TAS3002PFB in existing designs? A: The PCM3070IRHBT provides functional audio processing capability with 2-channel configuration and I2C interface support. However, package form factor differs (32-VQFN versus 48-TQFP), requiring PCB layout modifications. Supply voltage compatibility exists within the 3V to 3.6V range, and ROHS3 compliance is maintained.

Q: What are the key differences between the substitute options? A: PCM3070IRHBT offers 32-bit resolution, dual ADC/DAC architecture, and multi-protocol interface support (I2C, Serial, SPI) with extended temperature range. Z87L1016ASGR2961 provides 2-channel audio processing with serial interface and maintains the original supply voltage specification. Both are active products with ROHS3 compliance.

Q: Does package size affect substitution feasibility? A: Yes. The TAS3002PFB uses 48-TQFP (7x7) packaging, while PCM3070IRHBT uses 32-VQFN (5x5) and Z87L1016ASGR2961 uses a different package configuration. Physical board layout redesign is necessary for either substitute implementation.

Q: Are both substitute parts ROHS3 compliant? A: Yes. Both PCM3070IRHBT and Z87L1016ASGR2961 maintain ROHS3 compliance status, matching the regulatory requirements of the original TAS3002PFB.
