TAS5601DCA Equivalent & Substitute Parts

Part Overview

The TAS5601DCA is a Class D amplifier IC manufactured by Texas Instruments, designed for 2-channel stereo or 4-channel quad audio amplification applications. This device delivers 20W per channel at 8Ω in stereo configuration or 19W per channel at 4Ω in quad configuration. The TAS5601DCA is designated as Last Time Buy, indicating that this part number will no longer be manufactured. Identification of equivalent substitute parts is necessary to ensure continued design support and component availability for new production builds and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5601DCA is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier type: Class D topology
• Manufacturer: Texas Instruments
• Supply voltage range overlap with original specification (10V ~ 26V)
• RoHS3 compliance and REACH unaffected status
• Surface mount packaging technology
• Operating temperature range compatibility

Substitution Logic: The TAS5805MPWPR is identified as a manufacturer-recommended substitute. While the TAS5805MPWPR operates as a 1-channel (Mono) or 2-channel (Stereo) device compared to the TAS5601DCA's 2-channel or 4-channel capability, it maintains Class D amplifier topology, Texas Instruments manufacture, and overlapping supply voltage specifications. The TAS5805MPWPR supports the stereo configuration of the TAS5601DCA with higher output power capability (23W x 2 @ 8Ω versus 20W x 2 @ 8Ω). Both devices share identical RoHS3 compliance, MSL rating, and REACH status.

Parameter Comparison

Engineering Selection Recommendations

For Stereo (2-Channel) Applications: The TAS5805MPWPR is suitable as a direct substitute for stereo configurations. The substitute provides higher output power (23W x 2 @ 8Ω) compared to the original part (20W x 2 @ 8Ω), with identical RoHS3 compliance and MSL rating. The TAS5805MPWPR maintains active product status, ensuring long-term availability and manufacturing support. The extended supply voltage range (4.5V ~ 26.4V) provides additional design flexibility compared to the TAS5601DCA (10V ~ 26V).

For Quad (4-Channel) Applications: The TAS5805MPWPR does not support 4-channel configuration. Applications requiring quad-channel amplification cannot use this substitute without circuit redesign. Alternative solutions must be evaluated for quad-channel requirements.

Compliance and Regulatory Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. MSL rating is identical (Level 3, 168 Hours), requiring equivalent moisture control during storage and handling.

Temperature Range Consideration: The TAS5601DCA operates from -40°C to 85°C, while the TAS5805MPWPR operates from -25°C to 85°C. Applications requiring operation below -25°C ambient temperature cannot use the substitute without thermal management verification.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWPR replace the TAS5601DCA in all applications?

A: The TAS5805MPWPR is suitable for 2-channel stereo applications only. It cannot replace the TAS5601DCA in 4-channel quad configurations. Verify your application's channel requirement before substitution.

Q: What is the difference in output power between these parts?

A: In stereo configuration at 8Ω load, the TAS5805MPWPR delivers 23W per channel compared to 20W per channel for the TAS5601DCA. This represents a 15% increase in available output power.

Q: Are there package compatibility issues between these parts?

A: Yes. The TAS5601DCA uses a 56-PowerTFSOP package (0.240" width), while the TAS5805MPWPR uses a 28-PowerTSSOP package (0.173" width). PCB layout and footprint modifications are required for substitution. Pin configuration and signal routing must be verified against device datasheets.

Q: What is the minimum supply voltage for each part?

A: The TAS5601DCA requires minimum 10V supply voltage. The TAS5805MPWPR operates at lower minimum voltage of 4.5V, providing design flexibility for lower-voltage applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the TAS5601DCA and TAS5805MPWPR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature range difference?

A: The TAS5601DCA operates from -40°C to 85°C. The TAS5805MPWPR operates from -25°C to 85°C. Applications requiring operation below -25°C must use the original TAS5601DCA or identify alternative solutions.

Q: Why is the TAS5601DCA designated as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments will discontinue manufacturing this part number. The TAS5805MPWPR is designated as Active, ensuring continued availability and manufacturing support for new designs.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both parts carry MSL Level 3 rating with 168-hour floor life, requiring identical moisture control procedures during storage, handling, and assembly.
