TPA0212PWPRG4 Equivalent & Substitute Parts

Part Overview

The TPA0212PWPRG4 is a Class AB stereo amplifier IC manufactured by Texas Instruments, designed for 2-channel stereo headphone applications. This device delivers 2.6W per channel at 3Ohm load impedance and operates across a 4.5V to 5.5V supply voltage range. The part integrates comprehensive audio processing features including depop circuitry, differential inputs, input multiplexer, mute control, shutdown functionality, thermal protection, and volume control.

The TPA0212PWPRG4 is currently discontinued at DiGi Electronics, with 1478 pieces available in new original stock. Identifying equivalent substitute parts is necessary to ensure continued design support, maintain supply chain flexibility, and access components with active manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPA0212PWPRG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier type: Class AB topology
• Channel configuration: 2-Channel stereo with headphone output capability
• Output power rating: 2.6W per channel at 3Ohm load
• Supply voltage: 4.5V to 5.5V operating range
• Integrated features: Depop, differential inputs, input multiplexer, mute, shutdown, thermal protection, volume control

Physical & Environmental Specifications:

• Package: 24-PowerTSSOP form factor (0.173" width, 4.40mm)
• Mounting: Surface mount technology
• Temperature range: -40°C to 85°C
• Compliance: ROHS3, MSL Level 2

Manufacturing & Availability:

• Base product number: TPA0212
• Manufacturer: Texas Instruments
• Regulatory compliance: REACH Unaffected, ECCN EAR99

Substitute parts must match all electrical specifications, package dimensions, and compliance certifications. Differences in product status (discontinued vs. active) do not affect electrical substitutability but impact supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

The TPA0212PWPR is a direct electrical and mechanical equivalent to the TPA0212PWPRG4. Both parts share identical specifications across all critical parameters: amplifier topology, output power rating, supply voltage range, integrated feature set, package dimensions, and environmental operating range.

The primary distinction between these parts is product status. The TPA0212PWPRG4 is discontinued at DiGi Electronics, while the TPA0212PWPR maintains active manufacturing status with significantly higher inventory availability (18897 pieces versus 1478 pieces). Both parts maintain full ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99).

For new designs or production requiring long-term supply assurance, the TPA0212PWPR is the appropriate selection due to its active product status and superior inventory position. For existing designs currently using the TPA0212PWPRG4, direct substitution with the TPA0212PWPR is electrically and mechanically valid without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TPA0212PWPR be used as a direct replacement for the TPA0212PWPRG4 in existing designs?

A: Yes. The TPA0212PWPR is electrically and mechanically equivalent to the TPA0212PWPRG4. All electrical specifications, output power ratings, supply voltage requirements, integrated features, package dimensions, and environmental operating ranges are identical. No circuit modifications or PCB layout changes are required.

Q: What is the difference between TPA0212PWPRG4 and TPA0212PWPR?

A: The parts are functionally identical. The difference is product status: TPA0212PWPRG4 is discontinued at DiGi Electronics with limited remaining inventory, while TPA0212PWPR is actively manufactured with higher stock availability. The suffix variation reflects different manufacturing batches or distribution channels from Texas Instruments.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 24-PowerTSSOP package with identical dimensions: 0.173" width and 4.40mm overall width. PCB footprints and land patterns are identical, requiring no layout modifications for substitution.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both TPA0212PWPRG4 and TPA0212PWPR are ROHS3 compliant, REACH Unaffected, and classified as ECCN EAR99. Both carry MSL Level 2 rating (1 Year). Regulatory and environmental compliance is equivalent.

Q: What is the base product number for these parts?

A: The base product number is TPA0212. Both the TPA0212PWPRG4 and TPA0212PWPR are variants of this base product, sharing the same core amplifier design and specifications.

Q: Which part should be selected for new production designs?

A: The TPA0212PWPR is recommended for new designs due to active manufacturing status and superior inventory availability. This ensures long-term supply chain stability and reduces procurement risk.
