TCA0372DP1 Equivalent & Substitute Parts

Part Overview

The TCA0372DP1 is a power amplifier integrated circuit manufactured by onsemi, featuring two independent circuits in an 8-DIP through-hole package. This component is classified as obsolete, indicating it is no longer in active production. The identification of equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity for applications currently utilizing this device.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TCA0372DP1 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Number of circuits: 2

Electrical Compatibility Criteria:

• Supply voltage range overlap
• Output current capability
• Input bias current characteristics
• Slew rate and bandwidth performance
• Operating temperature range coverage

The substitute parts TL062CP and TL062IP are J-FET amplifiers manufactured by Texas Instruments. Both devices share the identical 8-DIP package footprint and through-hole mounting configuration, enabling direct pin-compatible replacement. However, these substitutes operate as J-FET amplifiers rather than power amplifiers, resulting in significant differences in output current capability, supply current consumption, and operating specifications.

Parameter Comparison

Engineering Selection Recommendations

TL062IP is the preferred substitute when application requirements permit. This device is in active production status, ensuring long-term availability and supply chain stability. The TL062IP provides an extended operating temperature range of -40°C to 85°C, which encompasses the lower temperature boundary of the TCA0372DP1 and supports a broader range of environmental conditions. RoHS3 compliance aligns with modern regulatory requirements and procurement standards.

TL062CP serves as an alternative substitute with identical electrical characteristics to the TL062IP. However, the TL062CP operating temperature range is limited to 0°C to 70°C, which does not cover the full low-temperature specification of the original TCA0372DP1. Selection of TL062CP is appropriate only when application operating conditions remain within 0°C to 70°C.

Both TL062 variants present significant functional differences from the TCA0372DP1:

• Output current per channel is reduced from 1 A to 20 mA
• Supply current consumption is reduced from 8 mA to 200 µA per dual-channel configuration
• Minimum supply voltage requirement increases from 5 V to 10 V
• Maximum supply voltage decreases from 40 V to 30 V

These differences necessitate circuit-level evaluation to confirm compatibility with existing power delivery and load requirements.

Frequently Asked Questions (FAQ)

Q: Can TL062CP and TL062IP be used interchangeably with TCA0372DP1?

A: Both devices share identical 8-DIP package geometry and through-hole mounting, enabling physical pin-compatible installation. However, electrical performance differs significantly. The TL062 series provides substantially lower output current (20 mA versus 1 A per channel) and operates within a narrower supply voltage range (10 V to 30 V versus 5 V to 40 V). Circuit redesign may be required to accommodate these differences.

Q: What is the primary difference between TL062CP and TL062IP?

A: Both parts are functionally identical J-FET amplifiers with matching electrical specifications. The primary distinction is operating temperature range: TL062CP operates from 0°C to 70°C, while TL062IP operates from -40°C to 85°C. Selection depends on application environmental requirements.

Q: Why is the TCA0372DP1 classified as obsolete?

A: The TCA0372DP1 is no longer manufactured by onsemi. Existing inventory remains available from authorized distributors, but new production is not available. Applications requiring this device must transition to active alternatives or maintain existing stock.

Q: Are the TL062 substitutes RoHS compliant?

A: Yes, both TL062CP and TL062IP are ROHS3 compliant. The original TCA0372DP1 is RoHS non-compliant. This compliance difference may impact procurement eligibility depending on customer or regulatory requirements.

Q: What is the impact of reduced output current on circuit performance?

A: The TCA0372DP1 provides 1 A output current per channel, while TL062 variants provide 20 mA per channel. Applications requiring high output current or driving low-impedance loads cannot be directly substituted without additional output buffering or redesign of the load circuit.

Q: Can the TL062 operate with the full 5 V to 40 V supply range of the TCA0372DP1?

A: No. The TL062 series requires a minimum supply voltage of 10 V and supports a maximum of 30 V. Applications operating at 5 V supply voltage or above 30 V cannot use TL062 substitutes without power supply modification.
