TAS5112DFDR Equivalent & Substitute Parts

Part Overview

The TAS5112DFDR is a Class D stereo audio amplifier IC manufactured by Texas Instruments, part of the PurePath Digital™ series. This device delivers 62W per channel at 6Ω load across two channels in a 56-HTSSOP surface mount package. The TAS5112DFDR is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. Substitute parts must maintain identical electrical performance, thermal characteristics, and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the TAS5112DFDR is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Class D amplifier topology
• 2-Channel stereo output configuration
• 62W output power per channel at 6Ω load impedance
• Supply voltage range 16V to 25.5V
• Identical feature set: Depop, Digital Inputs, Mute, Short-Circuit and Thermal Protection, Shutdown

Mechanical & Environmental Criteria:

• 56-HTSSOP package footprint (56-PowerTSSOP, 0.240" × 6.10mm width)
• Surface mount mounting type
• Operating temperature range 0°C to 70°C
• MSL rating 3 (168 Hours)

Compliance Criteria:

• ROHS3 compliance
• REACH unaffected status
• EAR99 ECCN classification

The TAS5112ADFDR meets all substitution criteria as an active product variant within the same base product family (TAS5112).

Engineering Selection Recommendations

The TAS5112ADFDR is the direct substitute for the obsolete TAS5112DFDR. Selection is based on the following engineering factors:

Product Status: The TAS5112ADFDR maintains active product status with Texas Instruments, ensuring continued availability, technical support, and supply chain reliability. The TAS5112DFDR is obsolete and subject to discontinuation.

Electrical Equivalence: Both parts are identical in electrical specifications, including Class D topology, stereo output configuration, 62W per channel output power at 6Ω, and supply voltage range of 16V to 25.5V. Feature sets are identical across all protection and control functions.

Mechanical Compatibility: Both parts use the 56-PowerTSSOP package with identical footprint dimensions (0.240" × 6.10mm width), enabling direct PCB layout compatibility without redesign.

Compliance & Certification: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL rating of 3 (168 Hours), satisfying regulatory and environmental requirements.

Packaging Consideration: The TAS5112ADFDR is supplied in Tape & Reel (TR) packaging, which is standard for production environments and offers advantages in automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TAS5112ADFDR be used as a direct replacement for the TAS5112DFDR on existing PCBs?
