TAS5613ADKDR Equivalent & Substitute Parts

Part Overview

The TAS5613ADKDR is a Class D audio amplifier IC from Texas Instruments' PurePath™ HD series, designed for mono or stereo audio applications with maximum output power of 300W at 2Ω (single channel) or 200W at 3Ω (dual channel). The device integrates protection features including depop, differential inputs, short-circuit protection, thermal protection, and shutdown functionality. The TAS5613ADKDR is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5613ADKDR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical base product number (TAS5613)
• Identical amplifier type (Class D)
• Identical output configuration (1-Channel Mono or 2-Channel Stereo)
• Identical maximum output power specifications (300W @ 2Ω single channel; 200W @ 3Ω dual channel)
• Identical supply voltage range (18V ~ 38V)
• Identical operating temperature range (0°C ~ 70°C)
• Identical integrated protection features (Depop, Differential Inputs, Short-Circuit and Thermal Protection, Shutdown)

Mechanical Compatibility Criteria:

• Surface mount technology
• ROHS3 compliance
• REACH unaffected status

Package Variation Allowance: The TAS5613ADKDR is packaged in 44-HSSOP (0.433", 11.00mm Width) with exposed pad. Substitute parts may utilize different package configurations (such as 64-HTQFP) provided all electrical parameters remain identical and the substitute is from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TAS5613APHDR

The TAS5613APHDR is the manufacturer-recommended substitute for the obsolete TAS5613ADKDR. Both devices share identical electrical specifications, output power ratings, supply voltage requirements, operating temperature range, and integrated protection features. The substitute maintains full functional equivalence across all critical audio amplifier parameters.

Key Advantages of TAS5613APHDR:

• Active product status ensures ongoing availability and manufacturing support
• Lower moisture sensitivity level (MSL 3 versus MSL 4) provides improved handling characteristics during storage and assembly
• ROHS3 and REACH compliance maintained
• Identical electrical performance and protection features

Design Consideration: The TAS5613APHDR utilizes a 64-HTQFP (14x14) package compared to the 44-HSSOP package of the TAS5613ADKDR. This package difference requires PCB layout modification, including changes to pin routing, thermal management pad design, and component placement. Pin-to-pin compatibility does not exist; schematic and PCB redesign is necessary.

Compliance Status: Both the main part and substitute maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in target applications.

Frequently Asked Questions (FAQ)

Q1: Can the TAS5613APHDR be used as a direct pin-for-pin replacement for the TAS5613ADKDR?

A: No. While both devices are electrically equivalent, they use different package types (44-HSSOP versus 64-HTQFP). Direct pin-for-pin substitution is not possible. PCB layout redesign is required to accommodate the different package footprint and pin configuration.

Q2: Are the electrical specifications identical between TAS5613ADKDR and TAS5613APHDR?

A: Yes. Both devices deliver identical maximum output power (300W at 2Ω single channel; 200W at 3Ω dual channel), operate across the same supply voltage range (18V ~ 38V), support identical output configurations (mono or stereo), and integrate the same protection features (depop, differential inputs, short-circuit protection, thermal protection, shutdown).

Q3: Why is the TAS5613ADKDR classified as obsolete?

A: The TAS5613ADKDR has reached end-of-life status from Texas Instruments. The TAS5613APHDR represents the active continuation of this product line with identical electrical performance.

Q4: What is the significance of the different moisture sensitivity levels (MSL 4 versus MSL 3)?

A: MSL 3 (168 hours) is more favorable than MSL 4 (72 hours). The TAS5613APHDR allows longer storage periods at elevated humidity before assembly, reducing risk of moisture-induced failures during reflow soldering.

Q5: Are there any thermal management differences between the two packages?

A: The 44-HSSOP and 64-HTQFP packages have different thermal characteristics due to their distinct geometries and exposed pad designs. Thermal analysis specific to each package is required during PCB design to ensure adequate heat dissipation for the intended application.

Q6: Do both parts maintain the same regulatory compliance?

A: Yes. Both TAS5613ADKDR and TAS5613APHDR are ROHS3 compliant and REACH unaffected, ensuring compatibility with current environmental and regulatory requirements.

Q7: What parameters must remain identical for a substitute to be considered equivalent?

A: Substitution equivalence requires identical base product number, amplifier type (Class D), output configuration (mono/stereo), maximum output power ratings, supply voltage range, operating temperature range, integrated protection features, mounting type, and regulatory compliance status. Package type may differ provided all electrical parameters remain unchanged.
