Substitute Part Grouping Explanation

Substitution eligibility for the PCM2704DBG4 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Resolution (Bits): 16 b
• Sampling Rate (Per Second): 48k
• Data Interface: SPI, USB
• Voltage Supply Source: Analog and Digital
• Voltage - Supply: 3V ~ 3.6V, 5V
• Operating Temperature: -25°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 28-SSOP (0.209", 5.30mm Width)

The PCM2704DB qualifies as a direct substitute, maintaining identical electrical specifications and mechanical packaging. The distinction between these parts lies in product status and packaging format rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

The PCM2704DB serves as a functional equivalent to the PCM2704DBG4 for applications requiring 16-bit, dual-channel audio data acquisition at 48 kHz sampling rate with SPI and USB interface support. Both parts maintain identical electrical and mechanical specifications, including voltage supply ranges, operating temperature limits, and 28-SSOP surface mount packaging.

Selection between these parts should be based on product status considerations. The PCM2704DBG4 is discontinued at DiGi Electronics, while the PCM2704DB carries a "Not For New Designs" status. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications.

Packaging format differs between the two parts: PCM2704DB is supplied in tube format, whereas PCM2704DBG4 packaging format is not specified in available documentation. Procurement decisions should account for inventory availability and packaging compatibility with assembly processes.
