Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5614ADKDR is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type: Class D topology
• Output configuration: 1-Channel (Mono) or 2-Channel (Stereo) capability
• Maximum output power: 300W @ 2Ohm (mono); 200W @ 3Ohm per channel (stereo)
• Supply voltage range: 18V ~ 38V
• Integrated protection features: Depop, Digital Inputs, Short-Circuit and Thermal Protection, Shutdown
• Operating temperature range: 0°C ~ 70°C (TA)

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount
• Base product number: TAS5614 (same silicon die or functionally equivalent variant)
• RoHS3 compliance
• REACH unaffected status

Packaging Considerations: While the TAS5614ADKDR uses 44-HSSOP packaging, substitute parts may employ different package types (such as 64-HTQFP) provided the electrical specifications remain identical. Package differences require PCB layout redesign but do not affect functional performance when electrical parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

The TAS5614APHDR is the manufacturer-recommended substitute for the obsolete TAS5614ADKDR. Both devices share identical electrical specifications, including Class D amplifier topology, output power ratings, supply voltage range, protection features, and operating temperature range. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary difference between these parts is packaging format: the TAS5614ADKDR uses 44-HSSOP, while the TAS5614APHDR uses 64-HTQFP (14x14). This packaging change requires PCB layout redesign but does not affect electrical performance or functional compatibility. The TAS5614APHDR offers improved moisture sensitivity characteristics (MSL 3 versus MSL 4), providing enhanced reliability in humid storage and assembly environments.

The TAS5614APHDR is currently in Active product status, ensuring long-term availability and manufacturing support. Selection of this substitute is appropriate for new designs and production transitions from the obsolete TAS5614ADKDR.

Frequently Asked Questions (FAQ)

Q: Can the TAS5614APHDR directly replace the TAS5614ADKDR without PCB modifications?

A: No. While the electrical specifications are identical, the package types differ (44-HSSOP versus 64-HTQFP). PCB layout redesign is required to accommodate the different pin configuration and package dimensions. The TAS5614APHDR uses a larger 64-pin TQFP package compared to the 44-pin HSSOP of the original part.

Q: Are the electrical performance characteristics identical between these two parts?

A: Yes. Both the TAS5614ADKDR and TAS5614APHDR deliver identical electrical performance: 300W output power at 2Ohm (mono) or 200W per channel at 3Ohm (stereo), 18V to 38V supply voltage range, Class D topology, and identical protection features including depop, digital inputs, short-circuit protection, thermal protection, and shutdown functionality.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The TAS5614APHDR has MSL 3 (168 hours), while the TAS5614ADKDR has MSL 4 (72 hours). Lower MSL values indicate greater tolerance to moisture exposure during storage and assembly. The TAS5614APHDR's improved MSL rating provides enhanced reliability in humid environments and allows longer shelf life before component baking is required.

Q: Why is the TAS5614ADKDR classified as Obsolete?

A: The TAS5614ADKDR has reached end-of-life status. Texas Instruments recommends transitioning to the TAS5614APHDR for new designs and ongoing production. The substitute part is in Active status, ensuring continued manufacturing support and availability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TAS5614ADKDR and TAS5614APHDR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging formats are available for the TAS5614APHDR?

A: The TAS5614APHDR is supplied in Tape & Reel (TR) format. The original TAS5614ADKDR was available in Cut Tape (CT) and Digi-Reel® options. Packaging format selection depends on production volume and assembly line requirements.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the identical temperature range of 0°C to 70°C (TA), ensuring compatibility in equivalent thermal environments.
