Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5142DDVRG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier topology: Class D architecture
• Output configuration: 2-Channel stereo
• Power delivery: 100W per channel at 4Ω load
• Supply voltage range: 10.8V ~ 13.2V
• Integrated protection features: Short-circuit and thermal protection with shutdown capability
• Input interface: Digital inputs

Mechanical Equivalence Criteria:

• Package designation: 44-PowerTSSOP
• Physical dimensions: 0.244" width, 6.20mm width specification
• Mounting technology: Surface mount

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture sensitivity level: MSL 3 (168 Hours)
• REACH status: REACH Unaffected

The substitute part TAS5142DDVR differs from the main part only in packaging format (Tape & Reel versus the original specification) and product status (Active versus Discontinued). All electrical, thermal, and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The TAS5142DDVR is a direct functional equivalent to the TAS5142DDVRG4 for all applications requiring Class D stereo audio amplification at 100W per channel. Selection between these parts is determined by supply chain and packaging requirements rather than electrical or mechanical differences.

Primary Selection Criteria:

The TAS5142DDVR is the recommended selection for new designs and ongoing production due to active product status with Texas Instruments. This part maintains full electrical and mechanical compatibility with the discontinued TAS5142DDVRG4 while offering significantly higher inventory availability (25200 units versus 2150 units).

Packaging Consideration:

The TAS5142DDVR is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. If the original design specified a different packaging format, reel-based packaging remains compatible with standard surface mount assembly equipment.

Compliance Status:

Both parts maintain identical RoHS3 compliance, MSL 3 rating, and REACH unaffected status, ensuring regulatory equivalence across all jurisdictions and applications.

Frequently Asked Questions (FAQ)

Q: Can the TAS5142DDVR be used as a direct replacement for the TAS5142DDVRG4 in existing designs?

A: Yes. The TAS5142DDVR is electrically and mechanically identical to the TAS5142DDVRG4.
