TAS5707APHPR Equivalent & Substitute Parts

Part Overview

The TAS5707APHPR is a Class D stereo audio amplifier IC manufactured by Texas Instruments, designed to deliver 20.6W per channel at 8Ω load impedance. This device integrates digital audio processing with integrated protection features including short-circuit and thermal protection, making it suitable for compact audio amplification applications requiring dual-channel output.

The TAS5707APHPR carries a "Not For New Designs" product status, indicating that Texas Instruments has discontinued active development and support for this device. Organizations developing new products or requiring long-term component availability should evaluate equivalent alternatives that maintain functional compatibility while offering active product status and extended lifecycle support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5707APHPR is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier classification: Class D topology
• Output channel configuration: 2-Channel (Stereo) capability
• Supply voltage overlap: Minimum 8V to 24V operating range
• Surface mount packaging: Compatibility with automated assembly processes
• Protection features: Short-circuit and thermal protection integration

Lifecycle and Support Criteria:

• Product status transition from "Not For New Designs" to "Active"
• Maintained RoHS3 compliance and regulatory alignment
• Equivalent moisture sensitivity classification

The TAS5805MPWPR qualifies as a manufacturer-recommended substitute based on its Class D topology, stereo output capability, overlapping supply voltage range (4.5V ~ 26.4V encompasses the TAS5707APHPR range), active product status, and equivalent compliance certifications. The TAS5805MPWPR operates across an extended temperature range (-25°C ~ 85°C) and delivers higher output power density (23W x 2 @ 8Ω), providing performance headroom for new designs.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (TAS5707APHPR Retention): The TAS5707APHPR remains suitable for production continuation in established applications where component qualification has been completed and supply chain agreements are in place. Current inventory of 16,218 pieces supports near-term production requirements. Compliance certifications (ROHS3, REACH Unaffected, EAR99 classification) remain valid for existing product lines.

For New Design Initiatives: The TAS5805MPWPR is the manufacturer-recommended substitute for new product development. This device carries "Active" product status, ensuring long-term availability and continued manufacturer support. The TAS5805MPWPR provides enhanced performance specifications (23W x 2 @ 8Ω versus 20.6W x 2 @ 8Ω) and extended operating temperature range (-25°C ~ 85°C), supporting broader application environments. Inventory availability of 21,400 pieces ensures supply continuity. Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99) maintain regulatory alignment.

Package Transition Consideration: The TAS5805MPWPR utilizes a 28-HTSSOP package versus the TAS5707APHPR 48-HTQFP package. This represents a reduction in pin count and physical footprint, requiring PCB layout redesign. The smaller package footprint may provide space optimization benefits in compact audio applications.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWPR directly replace the TAS5707APHPR without PCB modifications?

A: No. The TAS5805MPWPR uses a 28-HTSSOP package while the TAS5707APHPR uses a 48-HTQFP package. Pin configurations differ, requiring PCB layout redesign and schematic verification. However, both devices maintain Class D amplifier topology and stereo output capability, supporting functional equivalence after proper circuit adaptation.

Q: What is the significance of the "Not For New Designs" status on the TAS5707APHPR?

A: This designation indicates that Texas Instruments has concluded active development and optimization of the TAS5707APHPR. The device remains available for existing production but is not recommended for new product development. Organizations should transition to the TAS5805MPWPR for designs entering production phases.

Q: Does the TAS5805MPWPR support the same supply voltage range as the TAS5707APHPR?

A: The TAS5805MPWPR supply voltage range (4.5V ~ 26.4V) encompasses the TAS5707APHPR range (8V ~ 24V). The TAS5805MPWPR extends the lower voltage limit to 4.5V and upper limit to 26.4V, providing broader application flexibility. Existing designs operating within 8V ~ 24V remain fully compatible.

Q: What output power difference exists between these devices at 8Ω load impedance?

A: The TAS5805MPWPR delivers 23W per channel at 8Ω, compared to 20.6W per channel for the TAS5707APHPR. This represents approximately 12% higher power output, providing performance margin for new designs without requiring supply voltage increases.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the TAS5707APHPR and TAS5805MPWPR carry ROHS3 compliance certification and REACH Unaffected status, maintaining equivalent regulatory alignment for applications requiring environmental compliance documentation.

Q: What is the operating temperature difference between these devices?

A: The TAS5707APHPR operates from 0°C ~ 85°C, while the TAS5805MPWPR operates from -25°C ~ 85°C. The TAS5805MPWPR supports extended low-temperature operation, enabling deployment in cold environment applications where the TAS5707APHPR would be unsuitable.

Q: Do both devices include identical protection features?

A: The TAS5707APHPR specifies integrated short-circuit and thermal protection features. The TAS5805MPWPR datasheet does not list specific protection features in the provided parameters. Circuit design verification is required to confirm protection feature equivalence during substitution evaluation.
