TDA7296S Equivalent & Substitute Parts

Part Overview

The TDA7296S is a Class AB linear amplifier integrated circuit manufactured by STMicroelectronics, designed for mono audio amplification applications. This device delivers 60W output power at 8Ω load impedance and operates across a dual supply voltage range of ±10V to ±35V. The TDA7296S incorporates integrated protection features including depop, mute, short-circuit protection, and thermal management, along with standby functionality.

The TDA7296S carries an obsolete product status. Identifying equivalent and substitute components is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TDA7296S is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier topology (Class AB)
• Output channel configuration (1-Channel Mono)
• Maximum output power rating (60W @ 8Ω)
• Supply voltage operating range (±10V ~ ±35V)
• Integrated protection feature set (Depop, Mute, Short-Circuit Protection, Thermal Protection, Standby)

Physical & Environmental Specifications:

• Mounting technology (Through Hole)
• Package form factor (Multiwatt-15 with Vertical, Bent and Staggered Leads)
• Operating temperature range (0°C ~ 70°C)

Regulatory & Compliance:

• RoHS3 compliance status
• REACH compliance status

Substitute parts must match all electrical specifications, physical package dimensions, and regulatory certifications to ensure direct functional and mechanical interchangeability without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The TDA7296 serves as a direct functional and mechanical equivalent to the TDA7296S. Both components are manufactured by STMicroelectronics and share identical electrical specifications, package geometry, and protection feature implementations.

Primary Selection Advantage: The TDA7296 maintains active product status with significantly higher inventory availability (17,849 pieces in stock versus 1,076 pieces for the TDA7296S). This availability differential ensures supply chain continuity and reduces procurement lead times for applications requiring mono Class AB amplification at 60W output power.

Compliance Equivalence: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and consumer applications. The TDA7296 carries MSL rating of 1 (Unlimited moisture sensitivity level) compared to the TDA7296S MSL rating of 3 (168 Hours), indicating improved moisture handling characteristics for the substitute part.

Packaging Consideration: The TDA7296 is supplied in tube packaging, while the TDA7296S packaging specification is not provided. Both utilize identical Multiwatt-15 physical form factors with vertical, bent, and staggered leads, ensuring direct board-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the TDA7296 replace the TDA7296S in existing circuit designs?

A: Yes. The TDA7296 provides complete electrical and mechanical equivalence to the TDA7296S. All amplifier specifications, protection features, supply voltage requirements, and output power ratings are identical. The Multiwatt-15 package geometry is unchanged, permitting direct socket substitution without circuit redesign or PCB layout modification.

Q: What is the difference between TDA7296S and TDA7296?

A: The primary differences are product status and packaging format. The TDA7296S is classified as obsolete, while the TDA7296 maintains active production status. The TDA7296 is supplied in tube packaging with improved moisture sensitivity characteristics (MSL 1 versus MSL 3). All electrical and functional specifications remain identical.

Q: Are there any thermal or reliability differences between these parts?

A: No thermal or reliability differences exist between the TDA7296 and TDA7296S. Both incorporate identical thermal protection mechanisms, operate across the same temperature range (0°C to 70°C), and employ the same Class AB amplifier topology with integrated short-circuit and thermal shutdown protection.

Q: Does the TDA7296 meet the same regulatory requirements as the TDA7296S?

A: Yes. Both the TDA7296 and TDA7296S are ROHS3 compliant and REACH unaffected. They satisfy identical regulatory and environmental compliance standards for industrial and consumer audio amplification applications.

Q: What is the significance of the MSL rating difference?

A: The TDA7296 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The TDA7296S carries MSL 3 (168 Hours), requiring controlled humidity storage conditions. For applications with extended shelf storage or humid environments, the TDA7296 provides superior moisture tolerance characteristics.

Q: Can I use the TDA7296 in high-temperature applications?

A: Both parts operate within the same temperature specification range of 0°C to 70°C (TA). Applications requiring operation outside this range require alternative component selection. The integrated thermal protection in both devices activates at junction temperature limits to prevent damage.

Q: Is the tube packaging of the TDA7296 compatible with automated assembly equipment?

A: Tube packaging is standard for through-hole components and is compatible with conventional pick-and-place and wave soldering assembly processes. Verify specific equipment compatibility with your manufacturing partner based on tube dimensions and component spacing specifications.
