PCM3006T Equivalent & Substitute Parts

Part Overview

The PCM3006T is a stereo audio interface codec manufactured by Texas Instruments, designed for 16-bit serial audio applications. This device integrates dual ADCs and DACs with Sigma-Delta conversion architecture, operating across analog and digital supply voltages of 2.7V to 3.6V. The PCM3006T is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while accommodating design constraints related to resolution, packaging, and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCM3006T is determined by the following critical parameters:

• Stereo Audio Architecture: Both ADCs and DACs must equal 2 / 2 configuration
• Serial Data Interface: Digital communication protocol must remain serial
• Sigma-Delta Conversion: Required for audio codec functionality
• Supply Voltage Compatibility: Analog and digital supply ranges must accommodate 2.7V ~ 3.6V operation
• Surface Mount Packaging: Mounting type must be surface mount
• Operating Temperature Range: Must support -25°C ~ 85°C minimum
• RoHS3 Compliance: Environmental and regulatory requirement
• Resolution Flexibility: 16-bit or higher resolution acceptable for forward compatibility

The PCM3002E qualifies as a direct substitute with identical packaging (24-SSOP), matching supply voltages, and higher resolution (20-bit). The PCM3060PW qualifies as a functional substitute with enhanced resolution (24-bit) and performance metrics, though it requires different packaging (28-TSSOP) and separate analog supply voltage (4.5V ~ 5.5V).

Parameter Comparison

Engineering Selection Recommendations

PCM3002E is the preferred substitute for direct replacement applications. It maintains identical supply voltage specifications (2.7V ~ 3.6V for both analog and digital), operates within the same temperature range, and uses compatible 24-SSOP packaging with minimal footprint variation. The PCM3002E is active in production status, ensuring long-term availability. Higher resolution (20-bit versus 16-bit) provides improved audio fidelity without requiring circuit redesign. Both devices are ROHS3 compliant with unlimited moisture sensitivity rating.

PCM3060PW is suitable for applications requiring enhanced audio performance and higher resolution (24-bit). This substitute introduces design considerations: the analog supply voltage requirement (4.5V ~ 5.5V) differs from the PCM3006T, necessitating separate power supply architecture. The 28-TSSOP package requires PCB layout modification. The PCM3060PW offers superior signal-to-noise ratio and dynamic range specifications. Moisture sensitivity level increases to MSL 2, requiring controlled storage conditions. This substitute is appropriate for new designs prioritizing audio quality over form factor constraints.

Both substitute parts maintain active production status, ensuring component availability and supply chain stability compared to the obsolete PCM3006T.

Frequently Asked Questions (FAQ)

Q: Can PCM3002E replace PCM3006T without circuit modification?

A: PCM3002E is compatible with existing PCM3006T designs. Both devices operate on identical analog and digital supply voltages (2.7V ~ 3.6V), support the same operating temperature range, and use compatible 24-SSOP packaging. The higher resolution (20-bit) is backward compatible with 16-bit audio systems. No circuit modification is required.

Q: What are the packaging differences between substitute parts?

A: PCM3006T uses 24-LSSOP (0.24", 6.00mm width). PCM3002E uses 24-SSOP (0.209", 5.30mm width), representing a minor footprint reduction. PCM3060PW uses 28-TSSOP (0.173", 4.40mm width), requiring PCB layout redesign. Pin count increases from 24 to 28 for the PCM3060PW.

Q: Why does PCM3060PW require different analog supply voltage?

A: PCM3060PW is designed for 4.5V ~ 5.5V analog supply operation, compared to 2.7V ~ 3.6V for PCM3006T and PCM3002E. This specification difference reflects the device architecture and performance characteristics. Designs using PCM3060PW must incorporate separate analog power supply conditioning.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. PCM3006T, PCM3002E, and PCM3060PW are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity difference between parts?

A: PCM3006T and PCM3002E have MSL 1 (unlimited moisture sensitivity), allowing indefinite storage without desiccant protection. PCM3060PW has MSL 2 (1 year), requiring controlled storage conditions and desiccant packaging for extended shelf life.

Q: Which substitute is recommended for new product designs?

A: Selection depends on design requirements. For direct replacement with minimal modification, PCM3002E is recommended. For applications requiring enhanced audio performance and higher resolution, PCM3060PW is appropriate, provided the design accommodates separate analog supply voltage and modified packaging.
