Substitute Part Grouping Explanation

Substitution of the PCM3002EG is determined by strict equivalence across the following critical parameters:

• Audio codec type: Stereo Audio
• Data interface protocol: Serial
• Resolution specification: 20-bit
• ADC/DAC configuration: 2 ADCs and 2 DACs
• Sigma-Delta conversion: Required
• Signal-to-noise ratio: 90 dB (ADCs) / 94 dB (DACs)
• Dynamic range: 90 dB (ADCs) / 94 dB (DACs)
• Supply voltage ranges: 2.7V to 3.6V (both analog and digital)
• Operating temperature range: -25°C to 85°C
• Package type: 24-SSOP with 0.209" width (5.30mm)

The PCM3003E meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The PCM3003E is the appropriate substitute for the obsolete PCM3002EG. Both components share identical electrical specifications, package geometry, and compliance classifications. The PCM3003E maintains active product status with current manufacturing availability, ensuring supply chain continuity. Both parts comply with ROHS3 and carry identical export classification (EAR99) and tariff codes (HTSUS 8542.39.0001). The 24-SSOP package footprint is identical, permitting direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)
