Substitute Part Grouping Explanation

Substitution for the PCM3010DBG4 is determined by strict equivalence across the following critical parameters:

• 24-bit resolution audio codec architecture
• Dual ADC and dual DAC configuration
• Serial data interface protocol
• Sigma Delta modulation technology
• Identical S/N ratio specifications (100 dB ADC / 104 dB DAC)
• Identical dynamic range specifications (102 dB ADC / 104 dB DAC)
• Dual voltage supply requirements (4.5V–5.5V analog, 3V–3.6V digital)
• Operating temperature range (-25°C to 85°C)
• 24-SSOP surface mount package with identical physical dimensions
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

The PCM3010DB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PCM3010DB is a direct functional equivalent to the PCM3010DBG4. Both devices share identical electrical specifications, package geometry, and pin configuration. The primary distinction is product status: the PCM3010DBG4 is discontinued, while the PCM3010DB remains in active production.

Selection of the PCM3010DB as a substitute is supported by:

• Complete parameter equivalence across all audio codec specifications
• Identical 24-SSOP package footprint for direct PCB compatibility
• Active product status ensuring continued availability
• Compliance with RoHS3 and REACH standards (PCM3010DBG4 certified; PCM3010DB compliance status should be verified with manufacturer documentation)

Frequently Asked Questions (FAQ)
