Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TDA7295S 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 (80W @ 8Ω)
• Supply voltage operating range (±10V ~ ±40V)
• Integrated protection feature set (Depop, Mute, Short-Circuit Protection, Thermal Protection, Standby)

Physical & Environmental Specifications:

• Mounting technology (Through Hole)
• Package form factor (Multiwatt-15 with Vertical, Bent and Staggered Leads)
• Operating temperature range (0°C ~ 70°C)

Regulatory & Compliance:

• RoHS3 compliance status
• REACH compliance status

Substitute parts must match all electrical specifications, package configuration, and compliance certifications to ensure functional and mechanical compatibility without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The TDA7295 serves as a direct functional equivalent to the TDA7295S. Both devices are manufactured by STMicroelectronics and share identical electrical specifications, package configuration, and protection feature sets.

Product Status Consideration: The TDA7295S is classified as obsolete, while the TDA7295 maintains active product status. For new designs and ongoing production requirements, the TDA7295 is the appropriate selection to ensure long-term supply chain availability and manufacturer support.

Compliance & Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions.

Packaging & Moisture Sensitivity: The TDA7295 is supplied in tube packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), compared to the TDA7295S with MSL 3 (168 Hours). This represents an improvement in handling and storage flexibility for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the TDA7295 directly replace the TDA7295S in existing circuit designs?

A: Yes. The TDA7295 is electrically and mechanically equivalent to the TDA7295S. Both devices feature identical Class AB amplifier topology, 80W output power at 8Ω, supply voltage range (±10V ~ ±40V), protection features, and Multiwatt-15 package configuration. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from TDA7295S to TDA7295?

A: The TDA7295S is classified as obsolete, while the TDA7295 maintains active product status. Transitioning to the TDA7295 ensures continued availability, manufacturer support, and supply chain reliability for both new production and field replacements.

Q: Are there packaging differences between these parts?

A: The TDA7295S and TDA7295 share identical package form factors (Multiwatt-15 with Vertical, Bent and Staggered Leads) and mounting technology (Through Hole). The primary packaging difference is the supplier delivery format: TDA7295S is supplied in standard packaging, while TDA7295 is supplied in tube packaging. Both are compatible with standard PCB assembly processes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TDA7295S and TDA7295 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations applicable to electronic components.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The TDA7295 has MSL 1 (Unlimited), while the TDA7295S has MSL 3 (168 Hours). MSL 1 indicates superior moisture resistance and more flexible storage and handling conditions. The TDA7295 requires less stringent moisture control during manufacturing, assembly, and storage processes.

Q: Are the operating temperature ranges identical?

A: Yes. Both devices operate across the same temperature range of 0°C to 70°C (TA), ensuring equivalent thermal performance in target applications.
