TAS5342DDVRG4 Equivalent & Substitute Parts

Part Overview

The TAS5342DDVRG4 is a Class D audio amplifier integrated circuit manufactured by Texas Instruments, part of the PurePath Digital™ series. This device supports 1-Channel (Mono) or 2-Channel (Stereo) operation with maximum output power of 200W at 2Ohm (mono) or 100W per channel at 4Ohm (stereo). The TAS5342DDVRG4 is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance, thermal characteristics, and physical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5342DDVRG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical Class D amplifier topology
• Matching output power specifications: 200W @ 2Ohm (mono) and 100W @ 4Ohm (stereo)
• Identical supply voltage range: 10.8V ~ 13.2V
• Identical operating temperature range: 0°C ~ 70°C
• Identical feature set: Digital PWM Inputs, Short-Circuit and Thermal Protection, Shutdown

Physical & Packaging Equivalence Requirements:

• Identical package type: 44-PowerTSSOP
• Identical physical dimensions: 0.244" × 6.20mm Width
• Surface mount configuration

Compliance & Regulatory Equivalence:

• ROHS3 Compliant status
• MSL Rating 3 (168 Hours)
• REACH Unaffected status

The substitute part TAS5342DDVR meets all electrical, physical, and regulatory equivalence criteria and is therefore a valid direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The TAS5342DDVR is a direct electrical and mechanical equivalent to the TAS5342DDVRG4. Both components are manufactured by Texas Instruments and share identical specifications across all critical performance parameters: Class D amplifier topology, output power ratings, supply voltage range, operating temperature range, package configuration, and feature set.

The primary distinction between these parts is packaging format: the TAS5342DDVRG4 is supplied in tube packaging, while the TAS5342DDVR is supplied in Tape & Reel (TR) format. This difference affects only the delivery and handling method and does not impact electrical performance or PCB-level compatibility.

Both parts carry legacy product status. The TAS5342DDVRG4 is discontinued at DiGi Electronics, and the TAS5342DDVR is marked as Not For New Designs. Both maintain full ROHS3 compliance and REACH Unaffected status, confirming regulatory equivalence.

For applications currently using TAS5342DDVRG4, the TAS5342DDVR provides functional continuity. Packaging format selection should be based on procurement and assembly process requirements rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can TAS5342DDVR directly replace TAS5342DDVRG4 on a PCB?

A: Yes. Both parts are identical in electrical performance, thermal characteristics, and physical package dimensions (44-PowerTSSOP, 0.244" × 6.20mm). No PCB redesign or layout modification is required.

Q: What is the difference between TAS5342DDVRG4 and TAS5342DDVR?

A: The components are electrically and mechanically identical. The only difference is packaging format: TAS5342DDVRG4 is supplied in tube packaging, while TAS5342DDVR is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but not component performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both TAS5342DDVRG4 and TAS5342DDVR are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What is the MSL rating for these components?

A: Both parts have MSL Rating 3 (168 Hours), indicating moderate moisture sensitivity. Standard moisture control procedures during storage and assembly are required.

Q: Can these parts be used in new designs?

A: Both parts carry legacy product status. TAS5342DDVRG4 is discontinued at DiGi Electronics, and TAS5342DDVR is marked as Not For New Designs. For new applications, consult Texas Instruments for current-generation Class D amplifier alternatives.

Q: What are the output power specifications?

A: Maximum output power is 200W in mono configuration at 2Ohm load, or 100W per channel in stereo configuration at 4Ohm load. Supply voltage range is 10.8V ~ 13.2V.

Q: What is the operating temperature range?

A: Both parts operate from 0°C to 70°C (TA). Thermal protection is integrated to prevent damage under high-temperature conditions.
