Substitute Part Grouping Explanation

Substitution of the TCA0372DWR2 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Amplifier Type: Power
• Number of Circuits: 2
• Slew Rate: 1.4 V/µs
• Gain Bandwidth Product: 1.4 MHz
• Current - Input Bias: 100 nA
• Voltage - Input Offset: 1 mV
• Current - Output / Channel: 1 A
• Voltage - Supply Span: 5V to 40V
• Operating Temperature Range: -40°C to 125°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The TCA0372DWR2G qualifies as a direct substitute based on complete alignment with all critical electrical specifications and identical mechanical packaging. The primary distinction between these parts is product status and compliance certification, not functional performance.

For Existing Inventory Management: The TCA0372DWR2 remains functionally interchangeable with the TCA0372DWR2G in applications where RoHS compliance is not a regulatory requirement. Both parts share identical electrical performance characteristics, including slew rate, gain bandwidth product, input bias current, and output current capability. The primary differentiators are product lifecycle status and environmental compliance certifications.

Supply Chain Considerations: The TCA0372DWR2G demonstrates significantly higher inventory availability (38,200 pieces) compared to the obsolete TCA0372DWR2 (2,050 pieces), supporting long-term production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the TCA0372DWR2G be used as a direct replacement for the TCA0372DWR2 in existing circuit designs?

A: Yes. The TCA0372DWR2G is electrically and mechanically equivalent to the TCA0372DWR2. Both devices share identical specifications for amplifier type, circuit count, slew rate, gain bandwidth product, input bias current, input offset voltage, output current capability, and supply voltage range. The 16-SOIC package dimensions and surface mount configuration are identical, enabling direct PCB substitution without design modification.

Q: What is the difference in current supply between these two parts?

A: The TCA0372DWR2 specifies 8mA supply current, while the TCA0372DWR2G specifies 5mA supply current. This represents an improvement in power efficiency for the active part. Both values remain within acceptable operating parameters for the device category and do not affect functional compatibility or circuit performance.

Q: Are there any compliance or certification differences between the TCA0372DWR2 and TCA0372DWR2G?

A: Yes. The TCA0372DWR2G is ROHS3 compliant, while the TCA0372DWR2 is RoHS non-compliant. Both parts maintain REACH Unaffected status. The TCA0372DWR2G carries a Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), compared to MSL 1 (Unlimited) for the TCA0372DWR2. These differences reflect updated manufacturing standards and environmental regulations applicable to the active product.

Q: Is the 16-SOIC package identical for both parts?

A: Yes. Both the TCA0372DWR2 and TCA0372DWR2G utilize the 16-SOIC package with dimensions of 0.295 inches (7.50mm width). The package footprint, pin configuration, and surface mount characteristics are identical, ensuring mechanical compatibility on printed circuit boards.

Q: Why is the TCA0372DWR2 classified as obsolete?

A: The TCA0372DWR2 has reached end-of-life status in onsemi's product portfolio. The TCA0372DWR2G represents the current active equivalent, incorporating updated compliance certifications and manufacturing processes. For all new designs and ongoing production, the TCA0372DWR2G is the specified part number.

Q: What applications are suitable for these power amplifier devices?

A: The TCA0372DWR2 and TCA0372DWR2G are dual-circuit power amplifiers designed for applications requiring 1A output current per channel, moderate bandwidth (1.4 MHz), and wide supply voltage operation (5V to 40V). Typical applications include audio amplification, motor control drivers, and general-purpose power amplification in industrial and consumer electronics.
