Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5601DCAR is determined by the following critical parameters:

Amplifier Classification: Both the main part and substitute must be Class D amplifier ICs to maintain equivalent operational characteristics and control methodology.

Output Configuration Compatibility: The TAS5601DCAR supports 2-channel stereo or 4-channel quad operation. Substitute parts must support at least 2-channel stereo configuration to maintain minimum functional compatibility.

Power Output Requirements: The TAS5601DCAR delivers 20W per channel at 8Ω load impedance. Substitute parts must meet or exceed this power specification at equivalent load conditions.

Supply Voltage Range: The TAS5601DCAR operates across 10V to 26V. Substitute parts must support overlapping or equivalent voltage ranges to ensure proper operation in existing power supply designs.

Package and Mounting: Surface mount technology is required. The package footprint and pin count must be compatible with existing PCB layouts, or redesign must be acceptable.

Compliance and Certifications: RoHS3 compliance and equivalent regulatory status (REACH, ECCN, HTSUS) must be maintained.

Operating Temperature Range: The TAS5601DCAR operates from -40°C to 85°C. Substitute parts must support equivalent or wider temperature ranges for the intended application environment.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TAS5601DCAR is designated Last Time Buy, indicating discontinued production. The TAS5805MPWPR is Active status, ensuring ongoing availability and long-term supply chain stability.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and equivalent ECCN and HTSUS classifications, ensuring regulatory continuity.

Power Delivery: The TAS5805MPWPR delivers 23W per channel at 8Ω in stereo configuration, exceeding the TAS5601DCAR specification of 20W per channel. This provides improved performance headroom for stereo applications.

Voltage Supply Compatibility: The TAS5805MPWPR supports 4.5V to 26.4V, extending the lower voltage limit compared to the TAS5601DCAR (10V to 26V). This enables operation in lower-voltage supply designs.

Temperature Range: The TAS5601DCAR supports -40°C to 85°C operation. The TAS5805MPWPR supports -25°C to 85°C. Applications requiring operation below -25°C must retain the TAS5601DCAR or identify alternative solutions.

Package Footprint: The TAS5805MPWPR uses a smaller 28-pin package versus the 56-pin package of the TAS5601DCAR. PCB layout redesign is required for substitution.

Output Configuration Limitation: The TAS5805MPWPR supports mono or stereo operation only. Applications requiring 4-channel quad amplification cannot use this substitute without architectural redesign.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWPR directly replace the TAS5601DCAR in a 4-channel quad amplifier design?

A: No. The TAS5805MPWPR supports maximum 2-channel stereo operation, while the TAS5601DCAR supports 4-channel quad operation. Designs requiring 4-channel amplification cannot use the TAS5805MPWPR as a direct substitute.

Q: Is the TAS5805MPWPR suitable for stereo applications currently using the TAS5601DCAR?

A: The TAS5805MPWPR is suitable for stereo applications from a functional and power delivery perspective. However, the smaller 28-pin package requires PCB layout redesign. The lower operating temperature minimum (-25°C versus -40°C) must be evaluated against application requirements.

Q: What is the impact of the package size difference between these parts?

A: The TAS5601DCAR uses a 56-pin package (0.240" width), while the TAS5805MPWPR uses a 28-pin package (0.173" width). Direct pin-for-pin substitution is not possible. PCB redesign is required to accommodate the different footprint and pin configuration.

Q: Does the TAS5805MPWPR provide equivalent power output in stereo mode?

A: The TAS5805MPWPR delivers 23W per channel at 8Ω in stereo mode, compared to 20W per channel for the TAS5601DCAR. This represents a 15% increase in power delivery at equivalent load impedance.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and equivalent ECCN and HTSUS classifications. No regulatory barriers exist to substitution from a compliance perspective.

Q: What supply voltage considerations apply to substitution?

A: The TAS5805MPWPR supports 4.5V to 26.4V, while the TAS5601DCAR supports 10V to 26V. The TAS5805MPWPR enables operation at lower supply voltages. Applications operating below 10V require the TAS5601DCAR or alternative solutions.
