TDA7396 Equivalent & Substitute Parts

Part Overview

The TDA7396 is a Class AB linear amplifier integrated circuit manufactured by STMicroelectronics, designed for single-channel (mono) audio amplification applications. The device delivers 65W output power at 2Ω load impedance and operates across a supply voltage range of 8V to 18V. The TDA7396 integrates protection features including short-circuit and thermal protection, mute functionality, depop circuitry, and standby mode capability.

The TDA7396 carries an obsolete product status, indicating discontinuation from standard manufacturing. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for systems utilizing this amplifier IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TDA7396 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 (65W @ 2Ω load)
• Supply voltage operating range (8V to 18V)
• Integrated protection and control features (Depop, Differential Inputs, Mute, Short-Circuit Protection, Thermal Protection, Standby)

Physical and Mechanical Specifications:

• Mounting technology (Through Hole)
• Package form factor (Multiwatt-11 with Vertical, Bent and Staggered Leads)
• Operating temperature range (-40°C to 150°C junction temperature)

Compliance and Availability:

• Manufacturer (STMicroelectronics)
• Base product number (TDA7396)

Substitute parts must demonstrate complete alignment across all electrical, mechanical, and environmental parameters. Packaging format (tube versus alternative) does not affect functional substitution but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

The E-TDA7396 serves as a direct functional equivalent to the obsolete TDA7396. Both devices share identical electrical specifications, output power ratings, supply voltage requirements, and integrated protection features. Both utilize the same Multiwatt-11 through-hole package configuration, ensuring mechanical and electrical compatibility in existing PCB designs.

The primary distinction between the two parts relates to product lifecycle status and regulatory compliance:

TDA7396 (Obsolete): This part number is discontinued and no longer manufactured. The device is non-compliant with RoHS3 standards. Selection of this part number is appropriate only when existing inventory must be utilized or when legacy system repair requires exact original component matching.

E-TDA7396 (Active): This part number remains in active production by STMicroelectronics. The device achieves ROHS3 compliance and carries automotive-grade qualification. This part number is the appropriate selection for new designs, production continuity, and systems requiring regulatory compliance with modern environmental standards.

For applications requiring component substitution due to TDA7396 obsolescence, the E-TDA7396 provides complete functional and mechanical compatibility without design modification. The automotive-grade qualification of the E-TDA7396 indicates enhanced reliability screening and environmental stress testing, suitable for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the E-TDA7396 be used as a direct replacement for the TDA7396 in existing designs?

A: Yes. The E-TDA7396 is electrically and mechanically equivalent to the TDA7396. Both devices deliver identical output power (65W @ 2Ω), operate across the same supply voltage range (8V to 18V), integrate identical protection features, and utilize the same Multiwatt-11 through-hole package. No circuit modifications or PCB redesign is required for substitution.

Q: What is the difference between the TDA7396 and E-TDA7396 part numbers?

A: The TDA7396 and E-TDA7396 share the same base product number (TDA7396) and are manufactured by STMicroelectronics. The primary differences are product status and compliance: the TDA7396 is obsolete and non-compliant with RoHS3, while the E-TDA7396 is active production and ROHS3 compliant. The E-TDA7396 carries automotive-grade qualification. Functionally and electrically, both parts are identical.

Q: Are there packaging differences between TDA7396 and E-TDA7396?

A: Both parts use the Multiwatt-11 package with vertical, bent, and staggered leads. The primary packaging difference is the distribution format: the TDA7396 may be supplied in alternative packaging, while the E-TDA7396 is specified in tube packaging. This distinction affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: Why is the E-TDA7396 rated for automotive applications while the TDA7396 is not?

A: The E-TDA7396 carries automotive-grade qualification, indicating it has undergone enhanced reliability screening, environmental stress testing, and quality assurance procedures required for automotive applications. The TDA7396, being obsolete, does not carry this designation. For applications requiring automotive-grade components, the E-TDA7396 is the appropriate selection.

Q: Can the TDA7396 be used in new designs?

A: The TDA7396 is obsolete and no longer manufactured. For new designs, the E-TDA7396 is the appropriate selection. The E-TDA7396 provides identical functionality, active production status, and modern regulatory compliance (ROHS3).

Q: What is the operating temperature range for both parts?

A: Both the TDA7396 and E-TDA7396 operate across a junction temperature range of -40°C to 150°C (TJ), supporting applications across industrial, commercial, and automotive temperature environments.

Q: Are both parts RoHS compliant?

A: The TDA7396 is non-compliant with RoHS standards. The E-TDA7396 is ROHS3 compliant. For applications or markets requiring RoHS compliance, the E-TDA7396 must be selected.
