TAS5706APAPG4 Equivalent & Substitute Parts

Part Overview

The TAS5706APAPG4 is a Class D audio amplifier IC manufactured by Texas Instruments, designed for 2-channel (stereo) or 4-channel (quad) audio amplification applications. This device delivers 20.6W output power per channel at 8Ω load impedance and operates across a 10V to 26V supply voltage range. The part is housed in a 64-pin HTQFP (10x10mm) surface mount package.

The TAS5706APAPG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this amplifier topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5706APAPG4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Amplifier Type: Class D
• Output Configuration: 2-Channel (Stereo) or 4-Channel (Quad)
• Max Output Power: 20.6W x 2 @ 8Ω
• Supply Voltage Range: 10V ~ 26V
• Package Type: 64-PowerTQFP (10x10mm)
• Operating Temperature Range: 0°C ~ 85°C (TA)
• Mounting Type: Surface Mount

The TAS5706APAP has been identified as a manufacturer-recommended substitute. This part maintains identical electrical specifications, package configuration, and thermal operating parameters as the primary part number. The distinction between TAS5706APAPG4 and TAS5706APAP lies in packaging designation and product lifecycle status rather than functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

TAS5706APAP Selection Rationale:

The TAS5706APAP is the designated manufacturer-recommended substitute for the discontinued TAS5706APAPG4. Both parts are manufactured by Texas Instruments and maintain identical electrical performance specifications, package geometry, and compliance certifications.

The TAS5706APAP carries a "Last Time Buy" product status, indicating controlled availability through a defined procurement window. This part number offers significantly higher inventory availability (2400 units versus 791 units), providing improved supply chain security for new production orders and design transitions.

Both parts satisfy ROHS3 compliance and REACH unaffected status requirements. Moisture sensitivity classification (MSL 3, 168 hours) is identical, ensuring equivalent handling and storage protocols during manufacturing and assembly operations.

For applications currently specified with TAS5706APAPG4, direct substitution with TAS5706APAP is electrically and mechanically valid without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TAS5706APAP be used as a direct replacement for TAS5706APAPG4?

A: Yes. Both parts are Class D amplifier ICs with identical electrical specifications, output power ratings (20.6W x 2 @ 8Ω), supply voltage range (10V ~ 26V), operating temperature range (0°C ~ 85°C), and 64-PowerTQFP package configuration. No circuit modifications are required.

Q: What is the difference between TAS5706APAPG4 and TAS5706APAP?

A: The primary difference is product lifecycle status. TAS5706APAPG4 is discontinued at DiGi Electronics, while TAS5706APAP carries Last Time Buy status. The "G4" suffix in TAS5706APAPG4 represents a packaging or distribution designation. Electrical and functional specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 3, 168 hours). Handling, storage, and assembly requirements are equivalent.

Q: Which part should be selected for new designs?

A: TAS5706APAP is the appropriate selection for new designs. This part number offers superior inventory availability and defined procurement windows through Last Time Buy status, supporting production continuity and supply chain planning.

Q: Are the pin configurations and PCB footprints identical?

A: Yes. Both parts use the 64-PowerTQFP (10x10mm) surface mount package with identical pin assignments and footprint geometry. PCB designs require no modification for part substitution.

Q: What is the moisture sensitivity level, and what does it mean for handling?

A: Both parts are classified as MSL 3 with a 168-hour floor life. This indicates standard moisture sensitivity requiring controlled storage conditions and standard reflow soldering procedures during assembly. Parts must be stored in dry conditions and used within the specified floor life window after moisture barrier bag opening.
