TAS5630PHD Equivalent & Substitute Parts

Part Overview

The TAS5630PHD is a Class D audio amplifier IC manufactured by Texas Instruments, part of the PurePath™ HD series. This device supports 1-Channel (Mono) or 2-Channel (Stereo) configurations with maximum output power of 600W at 1-channel 2Ohm load or 300W at 2-channel 4Ohm load. The TAS5630PHD is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where this amplifier IC is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5630PHD is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Amplifier type: Class D
• Output configuration: 1-Channel (Mono) or 2-Channel (Stereo)
• Supply voltage range: 25V ~ 52.5V
• Package type: 64-TQFP Exposed Pad (14x14)
• Mounting type: Surface Mount
• Feature set: Depop, Differential Inputs, Short-Circuit and Thermal Protection, Shutdown

Mechanical Compatibility Requirements:

• Identical package footprint and pin count (64-pin HTQFP)
• Surface mount compatibility

The TAS5630BPHD qualifies as a substitute part because it maintains identical electrical specifications for supply voltage, output configuration, package type, mounting method, and feature set. The primary difference is reduced maximum output power in mono configuration (480W vs. 600W at 2Ohm), which represents a design variant within the same product family rather than a functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The TAS5630BPHD is the designated substitute for the TAS5630PHD based on the following engineering criteria:

Product Status Consideration: The TAS5630PHD is classified as "Not For New Designs," while the TAS5630BPHD maintains Active status. This distinction is significant for long-term supply chain reliability and technical support availability.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental restrictions.

Electrical Equivalence: The TAS5630BPHD operates within the identical supply voltage range (25V ~ 52.5V) and maintains the same output configuration flexibility (Mono or Stereo). The 2-channel 4Ohm output power specification is identical at 300W per channel.

Mechanical Compatibility: Identical package footprint (64-TQFP Exposed Pad, 14x14mm) and surface mount configuration ensure direct PCB compatibility without layout modifications.

Power Output Variance: The TAS5630BPHD delivers 480W in mono 2Ohm configuration compared to 600W for the TAS5630PHD. This 20% reduction in single-channel maximum power must be evaluated against application requirements. Applications requiring full 600W mono output at 2Ohm impedance cannot use the TAS5630BPHD as a direct substitute.

Moisture Sensitivity: The TAS5630BPHD exhibits improved moisture sensitivity (MSL 4 vs. MSL 5A), providing enhanced reliability in humid storage and assembly environments.

Frequently Asked Questions (FAQ)

Q: Can the TAS5630BPHD replace the TAS5630PHD in all applications?

A: The TAS5630BPHD is electrically and mechanically compatible for applications operating in stereo mode (2-channel @ 4Ohm, 300W per channel) or mono mode requiring up to 480W at 2Ohm. Applications requiring the full 600W mono output specification of the TAS5630PHD require alternative solutions.

Q: Are the package footprints identical between these parts?

A: Yes. Both the TAS5630PHD and TAS5630BPHD use the 64-TQFP Exposed Pad package with 14x14mm dimensions. No PCB layout modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The TAS5630PHD is designated "Not For New Designs," indicating end-of-life status with limited future availability. The TAS5630BPHD maintains Active status, ensuring continued manufacturing, technical support, and supply chain availability.

Q: Do the supply voltage specifications differ?

A: No. Both parts operate across the identical 25V to 52.5V supply voltage range, ensuring compatibility with existing power supply designs.

Q: How does the moisture sensitivity level affect component handling?

A: The TAS5630BPHD has MSL 4 (72-hour floor life) compared to the TAS5630PHD's MSL 5A (24-hour floor life). This means the TAS5630BPHD tolerates longer exposure to ambient humidity after moisture barrier bag opening, reducing risk of moisture-induced failures during assembly.

Q: Are the protection features identical?

A: Yes. Both parts include Depop, Differential Inputs, Short-Circuit Protection, Thermal Protection, and Shutdown features.
