Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCM2902BDBR is determined by the following critical parameters:

• Identical audio codec architecture (stereo, 16-bit resolution, 2 ADCs / 2 DACs)
• USB data interface compatibility
• Matching package type (28-SSOP surface mount)
• Equivalent signal-to-noise ratio and dynamic range specifications
• Compatible operating temperature range
• Identical RoHS and MSL compliance status

The PCM2902CDBR qualifies as a direct substitute based on these criteria. Both parts share the same base product number (PCM2902), identical functional specifications, and equivalent package geometry. The primary difference is supply voltage range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PCM2902CDBR is the qualified substitute for PCM2902BDBR applications. Both components maintain identical audio codec functionality, signal processing specifications, and package geometry. The PCM2902CDBR carries active product status from Texas Instruments, ensuring continued availability and manufacturing support compared to the PCM2902BDBR which is designated not for new designs.

Selection between these parts depends on system power supply architecture. The PCM2902BDBR operates at 4.35V to 5.25V supply voltage, while the PCM2902CDBR operates at 3.1V to 4.6V. Verify that the substitute part's voltage requirements align with the target application's power distribution design before implementation.

Both components maintain equivalent RoHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can PCM2902CDBR replace PCM2902BDBR in existing designs?

A: Yes, provided the application power supply operates within the PCM2902CDBR voltage range of 3.1V to 4.6V. If the original design uses 4.35V to 5.25V supply voltage, voltage regulation or power supply modification is required.

Q: Are the audio specifications identical between these parts?

A: Yes. Both parts provide 16-bit stereo audio codec functionality with 2 ADCs and 2 DACs, identical signal-to-noise ratios (89 dB ADC / 96 dB DAC), and equivalent dynamic range specifications (89 dB ADC / 93 dB DAC).

Q: Do both parts use the same package?

A: Yes. Both PCM2902BDBR and PCM2902CDBR use 28-SSOP surface mount packaging with 0.209" width (5.30mm). PCB layout and footprint compatibility is maintained.

Q: What is the difference in product status?

A: PCM2902BDBR is classified as not for new designs, indicating end-of-life status. PCM2902CDBR maintains active product status with ongoing manufacturing support from Texas Instruments.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant and carry MSL Level 1 (unlimited) moisture sensitivity classification, maintaining equivalent regulatory and environmental compliance.
