TAS5630APHD Equivalent & Substitute Parts

Part Overview

The TAS5630APHD is a Class D audio amplifier integrated circuit manufactured by Texas Instruments, designed for mono or stereo audio amplification applications. This device delivers up to 600W at 2Ω (single channel) or 300W per channel at 4Ω (stereo configuration) and operates within a 10.8V to 13.2V supply voltage range. The TAS5630APHD is currently designated as Last Time Buy, indicating that the manufacturer has discontinued or will discontinue production. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5630APHD is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier type: Class D topology
• Output channels: Mono or stereo capability
• Output power rating: Minimum 300W per channel at 4Ω or equivalent power delivery
• Supply voltage range: Must accommodate the operating range or be compatible with system design modifications

Physical and Environmental Compatibility:

• Mounting type: Surface mount technology
• Operating temperature range: 0°C to 70°C
• RoHS compliance: ROHS3 Compliant
• Package type: High pin-count surface mount packages

The TPA3255DDVR qualifies as a substitute based on its Class D amplifier architecture, stereo output capability, equivalent or superior power output specifications, surface mount packaging, matching operating temperature range, and ROHS3 compliance. However, the TPA3255DDVR operates at a different supply voltage range (18V ~ 53.5V), which represents a significant design parameter difference that must be evaluated within the context of the target application.

Parameter Comparison

Engineering Selection Recommendations

The TPA3255DDVR is the designated manufacturer-recommended substitute for the TAS5630APHD. Both devices are manufactured by Texas Instruments and share Class D amplifier architecture with equivalent power output capabilities at 2Ω load (600W single channel). Both devices maintain ROHS3 compliance and operate within the same temperature range (0°C to 70°C).

The primary distinction between these devices is the supply voltage range. The TAS5630APHD operates at 10.8V to 13.2V, while the TPA3255DDVR operates at 18V to 53.5V. This voltage difference necessitates evaluation of the target application's power supply architecture. The TPA3255DDVR offers broader voltage flexibility and is currently in Active product status, ensuring long-term availability and continued manufacturer support, whereas the TAS5630APHD is designated Last Time Buy.

The TPA3255DDVR provides additional features including depop functionality and short-circuit protection. The package footprint differs between the two devices (64-HTQFP versus 44-HTSSOP), requiring PCB layout modifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the TPA3255DDVR directly replace the TAS5630APHD without circuit modifications?

A: The TPA3255DDVR is functionally equivalent in terms of Class D amplification and power output capability. However, the supply voltage range differs significantly (18V ~ 53.5V for TPA3255DDVR versus 10.8V ~ 13.2V for TAS5630APHD). Direct substitution requires verification that the system power supply can accommodate the TPA3255DDVR voltage requirements. Additionally, the package footprint differs (44-HTSSOP versus 64-HTQFP), necessitating PCB layout redesign.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters for substitution are: amplifier type (Class D), output channel configuration (mono or stereo capability), maximum output power at specified load impedances (2Ω and 4Ω), supply voltage range, operating temperature range, and mounting technology (surface mount). Both devices must meet these criteria for functional equivalence.

Q: How do the package differences affect implementation?

A: The TAS5630APHD uses a 64-HTQFP (14x14) package, while the TPA3255DDVR uses a 44-HTSSOP package. The TPA3255DDVR has fewer pins and a smaller footprint. PCB layout, trace routing, and component placement must be redesigned to accommodate the different package geometry and pin configuration.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The TAS5630APHD has MSL 5A (24 Hours), while the TPA3255DDVR has MSL 3 (168 Hours). MSL 3 indicates lower moisture sensitivity and allows extended shelf life before soldering. The TPA3255DDVR provides more favorable handling and storage characteristics.

Q: Are both devices RoHS compliant?

A: Yes, both the TAS5630APHD and TPA3255DDVR are ROHS3 Compliant, meeting environmental and regulatory requirements for electronic components.

Q: Why is the TAS5630APHD designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued or will discontinue production of the TAS5630APHD. This designation signals that existing inventory is limited and future availability cannot be guaranteed. The TPA3255DDVR, with Active product status, represents the recommended path for new designs and ongoing production requirements.
