TDA7376PD Equivalent & Substitute Parts

Part Overview

The TDA7376PD is a Class AB stereo amplifier integrated circuit manufactured by STMicroelectronics, designed for 2-channel audio amplification applications. This device delivers 40W per channel at 4Ω load impedance and operates across a supply voltage range of 8V to 18V. The TDA7376PD is classified as an Active product with full production support and maintains ROHS3 compliance with REACH unaffected status.

Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable, while maintaining identical electrical performance and mechanical compatibility within the specified parameter constraints.

Substitute Part Grouping Explanation

Substitute parts for the TDA7376PD are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical amplifier classification (Class AB)
• Matching output configuration (2-Channel Stereo)
• Identical maximum output power specification (40W x 2 @ 4Ω)
• Identical supply voltage operating range (8V ~ 18V)
• Matching feature set (Depop, Differential Inputs, Mute, Short-Circuit and Thermal Protection, Standby)

Mechanical Equivalence Criteria:

• Identical package type (PowerSO-36 Exposed Top Pad)
• Identical mounting technology (Surface Mount)
• Identical operating temperature range (-40°C ~ 150°C TJ)

Compliance Equivalence Criteria:

• Identical RoHS status (ROHS3 Compliant)
• Identical REACH status (REACH Unaffected)
• Identical MSL rating (3, 168 Hours)

The TDA7376PDTR substitute maintains 100% parameter alignment with the TDA7376PD across all specified electrical, mechanical, and compliance dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the TDA7376PD and TDA7376PDTR are Active products with full manufacturing support from STMicroelectronics. Selection between these parts is determined by packaging and supply chain requirements rather than electrical or mechanical performance differences.

TDA7376PD is supplied in standard packaging configuration and is suitable for applications where standard component procurement channels are utilized.

TDA7376PDTR is supplied in Cut Tape (CT) and Digi-Reel® packaging, providing advantages for high-volume automated assembly operations and tape-and-reel handling systems.

Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and are suitable for applications requiring regulatory compliance in restricted substance directives. The MSL rating of 3 (168 Hours) applies uniformly across both part numbers, establishing identical moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Are TDA7376PD and TDA7376PDTR electrically identical?

A: Yes. Both parts are manufactured by STMicroelectronics using the same die and internal circuitry. They deliver identical electrical performance: 40W per channel at 4Ω load, Class AB amplification, 8V to 18V supply operation, and identical feature sets including Depop, Differential Inputs, Mute, Short-Circuit and Thermal Protection, and Standby functionality.

Q: What is the difference between these part numbers?

A: The difference is packaging and tape format. TDA7376PD uses standard packaging, while TDA7376PDTR is supplied in Cut Tape (CT) and Digi-Reel® format. This distinction affects supply chain logistics and automated assembly compatibility, not component performance.

Q: Can I substitute TDA7376PDTR for TDA7376PD on a PCB?

A: Yes. Both parts use identical PowerSO-36 Exposed Top Pad packages with identical pinouts, pad layouts, and thermal characteristics. PCB designs require no modification for substitution.

Q: Are there any thermal or operating temperature differences?

A: No. Both parts operate across the identical temperature range of -40°C to 150°C (junction temperature). Thermal performance and power dissipation characteristics are equivalent.

Q: Do these parts have different compliance certifications?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant and REACH Unaffected. MSL rating is 3 (168 Hours) for both part numbers, establishing identical moisture sensitivity and storage requirements.

Q: Which part should I select for new designs?

A: Selection depends on manufacturing requirements. For automated high-volume assembly with tape-and-reel handling, TDA7376PDTR is appropriate. For standard procurement channels, TDA7376PD is suitable. Electrical performance and reliability are identical.

Q: Is the TDA7376 base product number used for both variants?

A: Yes. Both TDA7376PD and TDA7376PDTR share the base product number TDA7376. The suffix designates packaging and tape format only.
