TAS5186DDVR Equivalent & Substitute Parts

Part Overview

The TAS5186DDVR is a 6-channel Class D amplifier IC manufactured by Texas Instruments, part of the PurePath Digital™ series. This device delivers 60W output at 3Ohm load (single channel) or 30W across five channels at 6Ohm load, operating within a 10.8V to 13.2V supply voltage range. The component features digital inputs, integrated short-circuit and thermal protection, and shutdown functionality, housed in a 44-PowerTSSOP surface-mount package.

The TAS5186DDVR is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility permits the use of active-status alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5186DDVR is determined by strict alignment across the following critical parameters:

Electrical Compatibility Requirements:

• Identical amplifier type (Class D)
• Identical output channel configuration (6-Channel)
• Identical maximum output power specifications (60W @ 3Ohm single channel; 30W @ 6Ohm five channels)
• Identical supply voltage range (10.8V ~ 13.2V)
• Identical feature set (Digital Inputs, Short-Circuit and Thermal Protection, Shutdown)

Mechanical Compatibility Requirements:

• Identical package type (44-PowerTSSOP)
• Identical physical dimensions (0.244", 6.20mm Width)
• Surface-mount mounting type

Regulatory & Environmental Compliance:

• ROHS3 Compliant status
• Moisture Sensitivity Level 3 (168 Hours)
• REACH Unaffected status

The TAS5186ADDVR meets all substitution criteria. This part maintains identical electrical performance, output specifications, and mechanical form factor while differing in product status (Active vs. Obsolete) and operating temperature range specification.

Parameter Comparison

Engineering Selection Recommendations

TAS5186ADDVR as Primary Substitute:

The TAS5186ADDVR is a direct functional equivalent to the TAS5186DDVR. Both components share identical electrical specifications, output power ratings, supply voltage requirements, and protective features. The mechanical form factor and package dimensions are identical, ensuring PCB-level compatibility without layout modifications.

Product Status Consideration:

The TAS5186DDVR is classified as obsolete, while the TAS5186ADDVR maintains active product status. This distinction indicates ongoing manufacturer support, availability through distribution channels, and continued compliance with current regulatory standards for the TAS5186ADDVR.

Compliance & Certification:

Both parts maintain ROHS3 compliance, identical moisture sensitivity ratings, and REACH unaffected status. No regulatory barriers exist to substitution.

Operating Temperature Specification Difference:

The TAS5186DDVR specifies a junction temperature (TJ) range of 0°C to 125°C, while the TAS5186ADDVR specifies an ambient temperature (TA) range of 0°C to 70°C. These represent different measurement methodologies rather than functional limitations. Applications operating within 0°C to 70°C ambient conditions encounter no thermal constraints with either part.

Packaging Format:

The TAS5186DDVR is supplied in bulk packaging, while the TAS5186ADDVR is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Can the TAS5186ADDVR replace the TAS5186DDVR in existing designs?

A: Yes. The TAS5186ADDVR is electrically and mechanically identical to the TAS5186DDVR. No circuit modifications, PCB layout changes, or firmware updates are required. Direct substitution is supported at the component level.

Q: What is the significance of the "A" designation in TAS5186ADDVR?

A: The "A" in the part number indicates a revision or variant designation assigned by Texas Instruments. In this case, the TAS5186ADDVR represents an active-status version of the TAS5186 base product, maintaining identical electrical and mechanical specifications to the obsolete TAS5186DDVR.

Q: Are there differences in thermal performance between these parts?

A: Both parts employ identical Class D amplifier architecture and are housed in the same 44-PowerTSSOP package. Thermal performance is equivalent. The difference in temperature specification notation (TJ vs. TA) reflects measurement methodology, not performance capability.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging is standard for automated assembly processes, with components wound on continuous tape for pick-and-place equipment. Bulk packaging is used for manual handling or lower-volume applications. Functionally, the components are identical; packaging format affects only procurement and assembly logistics.

Q: Can I use the TAS5186ADDVR in applications requiring the full 0°C to 125°C temperature range?

A: The TAS5186ADDVR specifies 0°C to 70°C ambient temperature operation. Applications requiring operation above 70°C ambient temperature should not use this substitute. Verify your application's thermal environment before selection.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the TAS5186DDVR and TAS5186ADDVR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What inventory considerations apply to these parts?

A: The TAS5186DDVR (obsolete) has 754 pieces in stock. The TAS5186ADDVR (active) has 2132 pieces in stock. For long-term supply chain planning, the active-status TAS5186ADDVR offers greater availability and ongoing manufacturer support.
