TAS5701PAPRG4 Equivalent & Substitute Parts

Part Overview

The TAS5701PAPRG4 is a Class D stereo audio amplifier integrated circuit manufactured by Texas Instruments, designed to deliver 20W per channel at 8Ω load impedance. This device is packaged in a 64-pin HTQFP (10x10mm) surface mount package and operates across a supply voltage range of 10.8V to 13.2V, making it suitable for automotive and consumer audio applications.

The TAS5701PAPRG4 has been discontinued at DiGi Electronics. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure drop-in replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAS5701PAPRG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier topology: Class D stereo configuration
• Output power rating: 20W per channel at 8Ω load
• Supply voltage range: 10.8V to 13.2V
• Operating temperature range: 0°C to 85°C

Mechanical Equivalence Criteria:

• Package type: 64-PowerTQFP (10x10mm)
• Mounting technology: Surface mount
• Pin count and pinout: 64-pin HTQFP

Compliance Equivalence Criteria:

• RoHS3 compliance status
• Moisture sensitivity level: MSL 3
• Base product number: TAS5701 series

Substitute parts must satisfy all three equivalence categories. Packaging format (tape & reel versus tube) does not affect electrical or mechanical compatibility and therefore does not disqualify a substitute part.

Parameter Comparison

Engineering Selection Recommendations

The TAS5701PAPR serves as a direct electrical and mechanical substitute for the TAS5701PAPRG4. Both parts share identical specifications across all critical parameters: amplifier topology, output power rating, supply voltage range, operating temperature range, package type, and compliance certifications.

The primary distinction between these parts is product status and packaging format. The TAS5701PAPRG4 is discontinued at DiGi Electronics, whereas the TAS5701PAPR maintains active product status with confirmed inventory availability (3200 units in stock). The TAS5701PAPR is supplied in tape & reel packaging format, which is standard for high-volume production environments and does not affect circuit-level performance or PCB assembly compatibility.

Both parts maintain ROHS3 compliance and identical moisture sensitivity specifications, ensuring equivalent reliability and handling requirements throughout the supply chain and manufacturing process.

Frequently Asked Questions (FAQ)

Q: Can the TAS5701PAPR be used as a direct replacement for the TAS5701PAPRG4 in existing designs?

A: Yes. The TAS5701PAPR is electrically and mechanically equivalent to the TAS5701PAPRG4. All electrical parameters, package dimensions, pinout, and compliance certifications are identical. No circuit modifications or PCB redesign is required.

Q: What is the difference between the TAS5701PAPRG4 and TAS5701PAPR?

A: The primary differences are product status and packaging format. The TAS5701PAPRG4 is discontinued and supplied in tube packaging. The TAS5701PAPR is actively manufactured and supplied in tape & reel format. Electrical and mechanical specifications are identical.

Q: Does the tape & reel packaging of the TAS5701PAPR affect PCB assembly compatibility?

A: No. Tape & reel packaging is a supply format used for automated pick-and-place assembly. Once the component is removed from the tape, it is physically and electrically identical to tube-packaged versions. PCB assembly compatibility is unaffected.

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

A: No. Both the TAS5701PAPRG4 and TAS5701PAPR maintain identical RoHS3 compliance status, moisture sensitivity level (MSL 3), and all other regulatory certifications.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: MSL 3 indicates that the component can be stored in standard conditions (30°C, 60% relative humidity) for up to 168 hours before soldering. Both parts have identical MSL ratings and require the same handling and storage protocols.

Q: Is the TAS5701PAPR available in higher volume quantities?

A: Yes. The TAS5701PAPR has confirmed inventory of 3200 units in stock, compared to 1117 units for the discontinued TAS5701PAPRG4. The active product status ensures ongoing availability for future orders.
