TAS5186DDVRG4 Equivalent & Substitute Parts

Part Overview

The TAS5186DDVRG4 is a 6-channel Class D amplifier IC manufactured by Texas Instruments, part of the PurePath Digital™ series. This device delivers 60W 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 integrates digital inputs, short-circuit protection, thermal protection, and shutdown functionality in a 44-PowerTSSOP surface-mount package.

The TAS5186DDVRG4 carries an Obsolete product status, indicating it is no longer in active production. Locating equivalent or substitute components becomes necessary for ongoing system support, maintenance, and new design implementations where this specific part number is specified or required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5186DDVRG4 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Identical Class D amplifier topology
• 6-channel output configuration
• Matching output power specifications: 60W @ 3Ohm (single channel) and 30W @ 6Ohm (five channels)
• Identical supply voltage range: 10.8V ~ 13.2V
• Presence of digital inputs, short-circuit protection, thermal protection, and shutdown features

Mechanical Compatibility Requirements:

• Surface-mount technology
• 44-PowerTSSOP package format with 0.244" width and 6.20mm dimensions
• Identical pin configuration and footprint

Compliance & Certification Requirements:

• ROHS3 compliance
• MSL rating of 3 (168 Hours)
• REACH Unaffected status

The TAS5186ADDVR qualifies as a direct substitute based on full alignment with all electrical, mechanical, and compliance parameters specified above.

Parameter Comparison

Engineering Selection Recommendations

The TAS5186ADDVR is a direct functional and mechanical substitute for the obsolete TAS5186DDVRG4. Both components share identical electrical specifications, package geometry, and compliance certifications.

Primary Advantage: The TAS5186ADDVR maintains Active product status with Texas Instruments, ensuring continued availability, technical support, and supply chain reliability. This addresses the primary limitation of the TAS5186DDVRG4, which is no longer manufactured.

Packaging Consideration: The TAS5186ADDVR is supplied in Tape & Reel (TR) format, whereas the TAS5186DDVRG4 was supplied in tube packaging. This difference affects handling and automated assembly processes but does not impact electrical or mechanical compatibility.

Operating Temperature Specification: The TAS5186DDVRG4 specifies junction temperature (TJ) operation to 125°C, while the TAS5186ADDVR specifies ambient temperature (TA) operation to 70°C. Both specifications are valid for their respective measurement methodologies and do not indicate reduced performance in the substitute part.

Compliance Status: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings, confirming suitability for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the TAS5186ADDVR be used as a direct replacement for the TAS5186DDVRG4 in existing designs?

A: Yes. The TAS5186ADDVR is electrically and mechanically equivalent. Both components deliver identical output power specifications, operate within the same supply voltage range, and share the same 44-PowerTSSOP package footprint. PCB layout and schematic modifications are not required.

Q: What is the significance of the Obsolete status for the TAS5186DDVRG4?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing this part number. The TAS5186ADDVR, carrying Active status, is the current production equivalent and is recommended for all new designs and ongoing procurement.

Q: Are there differences in the packaging format between these two parts?

A: Yes. The TAS5186DDVRG4 was supplied in tube packaging, while the TAS5186ADDVR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. If tube packaging is required, contact the supplier regarding availability of alternative packaging options for the TAS5186ADDVR.

Q: How do the operating temperature specifications differ?

A: The TAS5186DDVRG4 specifies junction temperature (TJ) to 125°C, while the TAS5186ADDVR specifies ambient temperature (TA) to 70°C. These represent different measurement methodologies. Both specifications are valid and do not indicate reduced performance. The junction temperature specification is typically higher than ambient temperature specification for the same device under identical operating conditions.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the TAS5186DDVRG4 and TAS5186ADDVR are ROHS3 compliant, REACH Unaffected, and carry identical MSL ratings of 3 (168 Hours). Both parts meet current environmental and regulatory standards.

Q: What inventory status should be considered when selecting between these parts?

A: The TAS5186ADDVR has 2132 pieces in stock with Active product status, ensuring reliable long-term availability. The TAS5186DDVRG4, though 884 pieces are currently in stock, carries Obsolete status and will not be replenished. For new projects and ongoing support, the TAS5186ADDVR is the recommended selection.
