Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5504APAGRG4 is determined by the following critical parameters:

Package Compatibility: The substitute part must use the same 64-TQFP (10x10) surface mount package to ensure PCB layout compatibility without redesign.

Interface Compatibility: Both I2C and I2S interface support are required to maintain communication protocol compatibility with existing system designs.

Supply Voltage Range: The substitute must operate within or encompass the 3.3V supply requirement of the original design.

Functional Classification: The substitute must perform audio modulation functions suitable for digital audio interfacing applications.

Regulatory Compliance: ROHS3 compliance and MSL rating of 4 (72 Hours) are mandatory for manufacturing and storage compatibility.

The TAS5508CPAGR meets all substitution criteria while offering enhanced functionality through 8-channel capability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TAS5508CPAGR is the manufacturer-recommended substitute for the obsolete TAS5504APAGRG4. Both parts maintain identical package geometry (64-TQFP 10x10), interface protocols (I2C, I2S), and regulatory compliance status (ROHS3, MSL 4). The TAS5508CPAGR operates within the 3.3V supply requirement with a specified range of 3V to 3.6V, providing supply voltage compatibility. The substitute part carries active product status, ensuring long-term availability and manufacturing support. Both parts are classified as REACH Unaffected and carry EAR99 ECCN designation.
