Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM1804DBRG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 24 bits
• Sampling Rate: 192 kHz
• Data Interface: I2S
• Number of Channels: 2
• Package / Case: 28-SSOP
• Voltage Supply: 3V ~ 3.6V, 4.75V ~ 5.25V
• Operating Temperature Range: -10°C ~ 70°C
• Mounting Type: Surface Mount

The PCM1804DBR meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PCM1804DBR is the direct substitute for the PCM1804DBRG4. Both components share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the PCM1804DBRG4 is discontinued, while the PCM1804DBR remains in active production with significantly higher inventory availability (25,300 units in stock versus 701 units for the original part).

From a compliance perspective, both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the PCM1804DBR be used as a direct replacement for the PCM1804DBRG4?

A: Yes. The PCM1804DBR is electrically and mechanically identical to the PCM1804DBRG4 across all specified parameters, including resolution, sampling rate, I2S interface, supply voltage, operating temperature, and 28-SSOP package dimensions.

Q: Are there any differences in packaging between these parts?

A: Both parts use the same 28-SSOP package with 0.209" width (5.30mm). The PCM1804DBR is available in Cut Tape (CT) and Digi-Reel packaging options, while the PCM1804DBRG4 packaging specification was not provided. This does not affect electrical compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the PCM1804DBRG4 and PCM1804DBR are ROHS3 compliant and REACH unaffected, ensuring compliance with environmental and hazardous substance regulations.

Q: Why is the PCM1804DBR recommended over the PCM1804DBRG4?

A: The PCM1804DBR is in active production status with substantially higher inventory availability. The PCM1804DBRG4 is discontinued, making the PCM1804DBR the practical choice for new designs and ongoing production requirements.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both parts operate across 3V to 3.6V and 4.75V to 5.25V supply ranges, with an operating temperature range of -10°C to 70°C.
