Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM4204PAPRG4 is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 216 kHz sampling rate
• Channel Configuration: 4-channel audio input
• Digital Interface: I2S protocol
• Package Compatibility: 64-pin PowerTQFP (10×10) surface mount
• Voltage Supply Requirements: Dual supply (3V–3.6V and 5V)
• Operating Temperature Range: −10°C to 70°C
• Compliance Standards: ROHS3, REACH Unaffected, EAR99 classification

The PCM4204PAPR variant meets all electrical and mechanical requirements for direct substitution. Both parts share the same base product number (PCM4204) and are manufactured by Texas Instruments with identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The PCM4204PAPR is the direct equivalent substitute for the discontinued PCM4204PAPRG4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications, package geometry, and compliance certifications. The PCM4204PAPR is currently in active production status with confirmed inventory availability (22,700 units), whereas the original part is discontinued. From a compliance perspective, both parts carry ROHS3 certification, REACH Unaffected status, and EAR99 export classification, ensuring regulatory equivalence. The packaging format (Cut Tape and Digi-Reel) of the substitute part accommodates standard manufacturing and assembly workflows. Selection of the PCM4204PAPR eliminates supply chain risk while maintaining full functional and mechanical compatibility with existing PCM4204PAPRG4 designs.

Frequently Asked Questions (FAQ)

Q: Can the PCM4204PAPR be used as a direct replacement for the PCM4204PAPRG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number, resolution, sampling rate, channel count, I2S interface, package type, and voltage supply requirements. The PCM4204PAPR is the active production equivalent.

Q: What is the difference between PCM4204PAPRG4 and PCM4204PAPR?

A: The primary difference is product status. The PCM4204PAPRG4 is discontinued, while the PCM4204PAPR remains in active production. All functional and electrical parameters are identical. The suffix variation reflects manufacturing date codes or packaging configurations, not performance differences.

Q: Are there any package or pinout differences?

A: No. Both parts use the 64-pin PowerTQFP (10×10) surface mount package with identical pinout and mechanical dimensions. PCB layouts and assembly processes require no modification.

Q: What are the compliance and regulatory considerations?

A: Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Regulatory documentation and certifications are equivalent between the two part numbers.

Q: Is the moisture sensitivity level the same?

A: Yes. Both parts carry MSL 3 (168 Hours) rating, requiring identical handling, storage, and reflow procedures during assembly.

Q: What supply voltage options are available?

A: Both parts support dual supply operation: 3V–3.6V for analog circuitry and 5V for digital logic. No supply configuration changes are required when substituting.
