TDA7375V Equivalent & Substitute Parts

Part Overview

The TDA7375V is a Class AB linear amplifier IC manufactured by STMicroelectronics, designed for 2-channel stereo or 4-channel quad audio amplification applications. The device delivers 40W per channel at 4Ω load in stereo configuration or 12W per channel at 2Ω load in quad configuration. The TDA7375V is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. Substitute parts with identical electrical and mechanical specifications ensure seamless integration into existing circuit designs without requiring board-level modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDA7375V is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier topology (Class AB)
• Output channel configuration (2-channel stereo or 4-channel quad capability)
• Maximum output power ratings at specified load impedances
• Supply voltage operating range (8V ~ 18V)
• Operating temperature range (-40°C ~ 150°C)
• Integrated protection features (Depop, Short-Circuit, Thermal Protection, Standby mode)

Mechanical and Physical Specifications:

• Package type: Multiwatt-15 with vertical, bent, and staggered leads
• Mounting technology: Through-hole
• Pin configuration and lead spacing

Compliance and Regulatory:

• RoHS3 compliance
• REACH status
• Moisture sensitivity level (MSL 1)

Parts meeting all these criteria are classified as direct substitutes. Variations in product status (active versus obsolete) or packaging format (tube versus alternative) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The E-TDA7375V is a direct electrical and mechanical substitute for the TDA7375V. Both parts share identical specifications across all critical amplifier parameters, package geometry, and compliance certifications.

Product Status Consideration: The TDA7375V is classified as obsolete, while the E-TDA7375V maintains active product status. For new designs, maintenance applications, or production continuity, the E-TDA7375V is the appropriate selection. The active status ensures ongoing availability and manufacturing support from STMicroelectronics.

Compliance and Certification: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. No additional qualification or testing is required for substitution based on regulatory or environmental compliance criteria.

Packaging and Grade Differences: The E-TDA7375V is supplied in tube packaging and carries an automotive grade designation. These attributes do not affect electrical performance or pin compatibility. The automotive grade indicates qualification for automotive temperature and reliability standards, providing additional assurance for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the E-TDA7375V replace the TDA7375V in existing circuit designs?

A: Yes. The E-TDA7375V is a direct substitute. All electrical specifications, output power ratings, supply voltage range, operating temperature range, protection features, and package geometry are identical. No circuit modifications are required.

Q: What is the difference between the TDA7375V and E-TDA7375V?

A: The primary differences are product status and packaging format. The TDA7375V is obsolete; the E-TDA7375V is active. The E-TDA7375V is supplied in tube packaging and carries an automotive grade designation. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the Multiwatt-15 package?

A: No. Both parts use the identical Multiwatt-15 package with vertical, bent, and staggered leads. Pin configuration, lead spacing, and through-hole mounting are identical. Direct PCB compatibility is confirmed.

Q: Does the automotive grade of the E-TDA7375V affect its use in non-automotive applications?

A: No. Automotive grade indicates additional qualification and reliability testing. The part functions identically in all applications within the specified electrical and thermal parameters. The automotive grade does not restrict use in other applications.

Q: What is the significance of the active product status of the E-TDA7375V?

A: Active product status indicates that STMicroelectronics continues to manufacture and support the E-TDA7375V. This ensures ongoing availability for procurement, technical support, and design continuity. The obsolete status of the TDA7375V makes the E-TDA7375V the recommended choice for all new and ongoing applications.

Q: Are RoHS3 compliance and REACH status identical between both parts?

A: Yes. Both the TDA7375V and E-TDA7375V are ROHS3 compliant and REACH unaffected. No additional compliance verification is required for substitution.

Q: Can the E-TDA7375V be used in both stereo and quad amplifier configurations?

A: Yes. The E-TDA7375V supports both 2-channel stereo (40W x 2 @ 4Ω) and 4-channel quad (12W x 4 @ 2Ω) configurations, identical to the TDA7375V. Circuit design determines the operational mode.
