TDA7293HS Equivalent & Substitute Parts

Part Overview

The TDA7293HS is a Class AB linear amplifier integrated circuit manufactured by STMicroelectronics, designed for mono audio amplification applications. This device delivers 100W output power at 4Ω load and operates across a wide supply voltage range of ±12V to ±50V. The TDA7293HS features integrated protection mechanisms including short-circuit and thermal protection, depop functionality, mute control, and standby mode.

The TDA7293HS carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or repair requirements for legacy audio amplification systems.

Substitute Part Grouping Explanation

Substitution eligibility for the TDA7293HS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Amplifier Type: Class AB
• Output Configuration: 1-Channel (Mono)
• Maximum Output Power: 100W @ 4Ω load
• Supply Voltage Range: ±12V ~ ±50V
• Mounting Type: Through Hole
• Base Product Number: TDA7293
• Package Type: Multiwatt-15
• Operating Temperature Range: 0°C ~ 70°C
• Protection Features: Short-Circuit, Thermal, Depop, Mute, Standby
• Regulatory Compliance: ROHS3, REACH Unaffected

The TDA7293V qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction between the main part and substitute relates to package orientation (horizontal versus vertical lead configuration) and product status (obsolete versus active).

Engineering Selection Recommendations

TDA7293V as Primary Substitute:

The TDA7293V is the appropriate substitute for the obsolete TDA7293HS. Both devices share identical electrical performance specifications, functional feature sets, and regulatory compliance certifications. The TDA7293V maintains active product status with STMicroelectronics, ensuring ongoing availability and supply chain support.

The distinction between these parts is limited to physical package orientation: the TDA7293HS features horizontal lead configuration while the TDA7293V features vertical lead configuration. Both are Multiwatt-15 through-hole packages with bent and staggered leads. PCB layout modifications may be required to accommodate the different lead orientation.

Selection of the TDA7293V is supported by:

• Identical Class AB amplifier topology and 100W output power specification
• Matching supply voltage range (±12V ~ ±50V)
• Equivalent protection and control features
• ROHS3 compliance and REACH unaffected status
• Active product status ensuring long-term availability

Frequently Asked Questions (FAQ)

Q: Can the TDA7293V directly replace the TDA7293HS without PCB modifications?

A: The TDA7293V and TDA7293HS are electrically identical but differ in package lead orientation. The TDA7293HS uses horizontal lead configuration while the TDA7293V uses vertical lead configuration. PCB layout modifications are required to accommodate the different lead orientation. Verify footprint compatibility with your circuit board design before implementation.

Q: Are the electrical specifications identical between TDA7293HS and TDA7293V?

A: Yes. Both devices deliver 100W output power at 4Ω load, operate across ±12V to ±50V supply voltage range, and incorporate identical protection features including short-circuit protection, thermal protection, depop, mute, and standby functionality. Operating temperature range is 0°C to 70°C for both parts.

Q: What is the significance of the TDA7293HS being obsolete?

A: The obsolete status indicates that STMicroelectronics has discontinued production of the TDA7293HS. The TDA7293V, which carries active product status, represents the current manufacturing equivalent. For new designs or ongoing production requirements, the TDA7293V should be specified to ensure supply chain continuity.

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

A: No. Both the TDA7293HS and TDA7293V are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. Moisture sensitivity level is 1 (Unlimited) for both devices.

Q: What is the difference between horizontal and vertical lead orientation in Multiwatt-15 packages?

A: Horizontal lead configuration (TDA7293HS) positions the leads in a horizontal plane relative to the package body, while vertical lead configuration (TDA7293V) positions the leads vertically. This affects PCB footprint design and component placement. Consult the device datasheets for specific lead positioning diagrams and footprint requirements.

Q: Can I use the TDA7293V in legacy equipment designed for the TDA7293HS?

A: Electrical substitution is valid. However, physical package orientation differences require verification that the PCB footprint accommodates the vertical lead configuration of the TDA7293V. If the original PCB is designed exclusively for the horizontal lead configuration of the TDA7293HS, PCB rework or redesign is necessary.
