Substitute Part Grouping Explanation

Substitution eligibility for the PCM1680DBQG4 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels
• Resolution: 24-bit
• Sampling Rate: 192 kHz
• Data Interface: I2S
• Supply Voltage: 5V (Analog and Digital)
• Operating Temperature Range: -25°C ~ 70°C
• Package Type: 28-SSOP
• Mounting Type: Surface Mount

The PCM1680DBQ meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent. Both parts share the same base product number (PCM1680) and identical performance specifications across all critical audio DAC parameters.

Parameter Comparison

Engineering Selection Recommendations

The PCM1680DBQ is the designated manufacturer-recommended substitute for the PCM1680DBQG4. Both components are based on the same PCM1680 base product architecture and provide identical electrical performance specifications. The PCM1680DBQ maintains active product status, ensuring continued availability for production and design implementation.

For applications requiring ROHS3 compliance verification, the PCM1680DBQG4 documentation explicitly confirms ROHS3 compliance status. The PCM1680DBQ substitute should be evaluated against specific compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the PCM1680DBQ be used as a direct replacement for the PCM1680DBQG4?

A: Yes. Both parts share identical electrical specifications across all critical parameters: 8-channel configuration, 24-bit resolution, 192 kHz sampling rate, I2S interface, 5V supply, and 28-SSOP package. The PCM1680DBQ is the manufacturer-recommended substitute.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 28-SSOP package with 0.154" width (3.90mm). Pinout and mechanical dimensions are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the difference in product status between these parts?

A: The PCM1680DBQG4 is discontinued at DiGi Electronics, while the PCM1680DBQ maintains active product status. This distinction affects long-term availability and supply chain planning.

Q: Are there compliance differences I should consider?

A: The PCM1680DBQG4 is explicitly ROHS3 compliant. The PCM1680DBQ compliance status is not specified in the provided data. Applications with mandatory ROHS3 requirements should confirm compliance documentation for the substitute part before implementation.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the PCM1680DBQG4 and PCM1680DBQ operate across the identical temperature range of -25°C to 70°C.
