Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAS3001CPWRG4 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Function: Audio Signal Processor or Stereo Audio Codec
• Number of Channels: 2-channel configuration
• Resolution: 32-bit processing capability
• Interface: I2C compatibility (primary) or Serial/SPI alternative interfaces
• Voltage Supply Range: Overlap with 3V to 3.6V operating window
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The substitute parts listed below meet these core electrical and mechanical requirements, enabling direct functional replacement in digital audio interfacing applications. Package differences are noted where they occur, as physical footprint changes may require PCB layout modifications.

Parameter Comparison

Engineering Selection Recommendations

PCM3070IRHBR is the primary substitute for the TAS3001CPWRG4. Both devices are manufactured by Texas Instruments and maintain ROHS3 compliance. The PCM3070IRHBR offers extended operating temperature range (-40°C to 85°C) compared to the original part, providing improved thermal performance. The device supports multiple interface protocols (I2C, Serial, SPI™), ensuring compatibility with existing I2C-based implementations. However, the package footprint differs (32-VFQFN versus 28-TSSOP), requiring PCB layout modifications. The PCM3070IRHBR is currently in active production status with established supply availability.

Z87L1016ASGR2961 is an alternative substitute manufactured by Zilog. This device maintains the same 2-channel audio processing capability and 3V to 3.6V supply voltage range as the original part. The Z87L1016ASGR2961 operates across a -25°C to 70°C temperature range and uses Serial interface communication. The 44-LQFP package represents a significant footprint change from the original 28-TSSOP, necessitating substantial PCB redesign. This part is currently in active production status.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the PCM3070IRHBR directly replace the TAS3001CPWRG4 without PCB modifications?

A: The PCM3070IRHBR provides functional equivalence for audio signal processing and 2-channel operation. However, the package footprint differs (32-VFQFN versus 28-TSSOP), requiring PCB layout changes. The I2C interface compatibility ensures software and firmware compatibility.

Q: What are the key differences between the two substitute parts?

A: The PCM3070IRHBR offers a wider operating temperature range (-40°C to 85°C) and supports multiple interface protocols (I2C, Serial, SPI™). The Z87L1016ASGR2961 maintains closer thermal specifications to the original part (-25°C to 70°C) but uses Serial interface only. Package sizes differ significantly between both substitutes and the original component.

Q: Are both substitute parts currently available?

A: Yes. The PCM3070IRHBR has 4961 units in stock, and the Z87L1016ASGR2961 has 999 units in stock as new original inventory.

Q: Does the moisture sensitivity level change affect handling procedures?

A: The original TAS3001CPWRG4 has MSL 1 (Unlimited), while both substitutes have MSL 3 (168 Hours). This requires stricter moisture control during storage and handling for the substitute parts, with baking procedures recommended if exposure exceeds 168 hours.

Q: Which substitute is recommended for new designs?

A: Selection depends on application requirements. The PCM3070IRHBR is recommended for applications requiring extended temperature operation or multiple interface protocols. The Z87L1016ASGR2961 is suitable for applications with thermal requirements closer to the original specification.
