Frequently Asked Questions (FAQ)

Q: Can the E-TDA7375AV replace the TDA7375AV in existing designs without PCB modification?

A: Yes. The E-TDA7375AV is electrically and mechanically equivalent to the TDA7375AV. Both devices use the Multiwatt-15 package with identical pin configuration, lead geometry, and through-hole mounting requirements. Direct substitution on existing PCBs is supported without circuit redesign or layout changes.

Q: What is the primary difference between TDA7375AV and E-TDA7375AV?

A: The primary differences are product status and compliance certification. The TDA7375AV is classified as Obsolete, while the E-TDA7375AV is Active. The E-TDA7375AV is RoHS3 compliant, whereas the TDA7375AV is RoHS non-compliant. Electrical performance and package specifications are identical.

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

A: No. Both devices operate within the same temperature range (-40°C ~ 150°C TJ), deliver identical output power specifications (43W x 2 @ 4Ω stereo; 12W x 4 @ 2Ω quad), and require the same supply voltage range (8V ~ 18V). Thermal protection and all integrated protection features are identical.

Q: What does the "E" prefix in E-TDA7375AV indicate?

A: The "E" prefix indicates the Automotive grade variant of the TDA7375AV base product. This designation reflects qualification for automotive environmental and reliability standards. The electrical and mechanical specifications remain unchanged from the base TDA7375AV.

Q: Is the Tube packaging of E-TDA7375AV compatible with existing component handling and storage procedures?

A: Tube packaging is a standard industrial packaging format for through-hole components. Compatibility with existing handling, storage, and insertion equipment depends on your specific assembly processes. Verify that your component placement and insertion equipment supports Tube-packaged through-hole devices.

Q: Can I use E-TDA7375AV in applications requiring RoHS compliance?

A: Yes. The E-TDA7375AV is RoHS3 compliant and is the appropriate selection for applications subject to RoHS regulatory requirements. The TDA7375AV is RoHS non-compliant and cannot be used in RoHS-regulated applications.

Q: Are both parts suitable for automotive applications?

A: The E-TDA7375AV carries explicit Automotive grade designation. The TDA7375AV does not carry this designation. For automotive applications, the E-TDA7375AV is the specified selection.
