TAS5630APHDR Equivalent & Substitute Parts

Part Overview

The TAS5630APHDR is a Class D amplifier integrated circuit manufactured by Texas Instruments, designed for audio amplification applications in mono or stereo configurations. This device is classified as Last Time Buy, indicating that it is no longer in active production and existing inventory represents the final availability from the manufacturer. The TAS5630APHDR operates as a high-power audio amplifier capable of delivering up to 600W at 2Ω load in single-channel configuration or 300W per channel at 4Ω in stereo mode. Due to its Last Time Buy status, identification of functionally equivalent substitute components is necessary for design continuity and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5630APHDR is determined by alignment of the following critical parameters:

Amplifier Classification: Both the main part and substitute must be Class D amplifier integrated circuits to maintain equivalent operational characteristics and efficiency profiles.

Output Configuration: The substitute must support stereo (2-channel) output capability, as this encompasses the functional range of the main part's mono or stereo operation.

Power Output Capability: The substitute must deliver equivalent or greater power output at standard load impedances (2Ω and 4Ω) to ensure functional compatibility in target applications.

Supply Voltage Compatibility: The substitute's supply voltage range must accommodate the operational requirements of the main part's voltage specification or provide extended range capability.

Package and Mounting: Surface mount technology and compatible package footprints ensure mechanical and thermal integration within existing PCB designs.

Compliance Standards: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity ratings to ensure manufacturing and storage compatibility.

The TPA3255DDVR qualifies as a substitute based on these criteria, with the distinction that it operates across an extended supply voltage range and is in Active product status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TAS5630APHDR is designated Last Time Buy, indicating cessation of production. The TPA3255DDVR maintains Active status, ensuring continued availability and long-term supply chain viability for new designs and production continuity.

Compliance and Certification: Both components are ROHS3 compliant, satisfying regulatory requirements for electronic component manufacturing and distribution. The TPA3255DDVR includes additional REACH compliance documentation and ECCN/HTSUS classification data, providing enhanced regulatory traceability for international applications.

Power Output Equivalence: The TPA3255DDVR delivers 315W per channel at 4Ω load, exceeding the TAS5630APHDR specification of 300W per channel. Both devices achieve 600W at 2Ω single-channel operation, confirming functional parity in high-impedance load scenarios.

Supply Voltage Range: The TPA3255DDVR operates across an extended supply voltage range (18V ~ 53.5V) compared to the TAS5630APHDR (10.8V ~ 13.2V). Applications utilizing the lower voltage range of the TAS5630APHDR require external voltage regulation or design modification to operate within the TPA3255DDVR minimum supply specification.

Package Footprint Differences: The TAS5630APHDR utilizes a 64-pin HTQFP package, while the TPA3255DDVR employs a 44-pin PowerTSSOP package. PCB layout redesign is required to accommodate the different pin count and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the TPA3255DDVR directly replace the TAS5630APHDR without PCB modification?

A: No. The TPA3255DDVR uses a 44-pin PowerTSSOP package versus the 64-pin HTQFP package of the TAS5630APHDR. PCB layout redesign is required to accommodate the different pin configuration and footprint geometry.

Q: What is the primary reason for seeking a substitute for the TAS5630APHDR?

A: The TAS5630APHDR is classified as Last Time Buy, meaning the manufacturer has discontinued production. Existing inventory represents final availability. The TPA3255DDVR is in Active production status, ensuring continued supply for future applications.

Q: Are the power output specifications equivalent between these two amplifiers?

A: The devices deliver equivalent power at 2Ω load (600W single-channel). At 4Ω stereo load, the TPA3255DDVR provides 315W per channel compared to 300W per channel for the TAS5630APHDR, representing a 5% increase in output capability.

Q: What supply voltage considerations apply when substituting these components?

A: The TAS5630APHDR operates at 10.8V ~ 13.2V, while the TPA3255DDVR requires 18V ~ 53.5V minimum supply voltage. Applications designed for the lower voltage range of the TAS5630APHDR must implement external voltage regulation or power supply redesign to meet the TPA3255DDVR minimum specification.

Q: Are both components RoHS compliant?

A: Yes. Both the TAS5630APHDR and TPA3255DDVR are ROHS3 compliant, satisfying regulatory requirements for hazardous substance restrictions in electronic components.

Q: What is the difference in moisture sensitivity between these amplifiers?

A: The TAS5630APHDR has a Moisture Sensitivity Level (MSL) of 5A (24 Hours), while the TPA3255DDVR has MSL 3 (168 Hours). The TPA3255DDVR demonstrates lower moisture sensitivity, allowing extended exposure to ambient humidity conditions before component degradation occurs.

Q: Can the TAS5630APHDR operate in mono configuration while the TPA3255DDVR is stereo-only?

A: The TAS5630APHDR supports both mono (1-channel) and stereo (2-channel) configurations. The TPA3255DDVR is stereo-only (2-channel). Applications requiring mono operation must retain the TAS5630APHDR or implement external bridging techniques with the TPA3255DDVR.
