DRV102T Equivalent & Substitute Parts

Part Overview

The DRV102T is a power switch/driver IC manufactured by Texas Instruments, designed for relay and solenoid driving applications. It features a 1:1 bipolar output configuration with 2A maximum output current, operating across a load voltage range of 8V to 60V. The device is packaged in TO-220-7 through-hole format and includes internal PWM capability with status flag output and comprehensive fault protection including current limiting and over-temperature shutdown.

The DRV102T is classified as obsolete. Identifying functionally equivalent active alternatives is essential for new designs, production continuity, and long-term component availability assurance.

Substitute Part Grouping Explanation

Substitution eligibility for the DRV102T is determined by the following critical parameters:

• Functional Architecture: 1:1 ratio, high-side bipolar output configuration with on/off control interface
• Output Capability: Maximum output current rating must meet or exceed application requirements; the DRV102T provides 2A
• Load Voltage Range: Operating range of 8V to 60V establishes the minimum acceptable voltage window
• Protection Features: Internal PWM, status flag output, current limiting, and over-temperature protection
• Operating Temperature Range: -55°C to 125°C ambient operation capability
• Compliance: ROHS3 compliance and EAR99 classification maintained across substitutes

The DRV104PWP qualifies as a manufacturer-recommended substitute based on identical functional architecture, matching protection features, and active product status. Differences in maximum output current (1.2A vs. 2A) and load voltage range (8V to 32V vs. 8V to 60V) represent design trade-offs that must be evaluated against specific application requirements.

DRV104PWP Substitution Viability

The DRV104PWP is an active product from Texas Instruments and represents the manufacturer-recommended substitute for the obsolete DRV102T. Both devices maintain ROHS3 compliance and identical operating temperature specifications (-55°C to 125°C).

Critical Design Considerations

1. Output Current Derating: The DRV104PWP maximum output current is 1.2A compared to the DRV102T's 2A. Applications requiring sustained currents above 1.2A cannot use this substitute without circuit redesign.

2. Load Voltage Ceiling: The DRV104PWP supports load voltages up to 32V, whereas the DRV102T operates to 60V. Applications requiring load voltages above 32V require alternative solutions.

3. Package Transition: The DRV102T uses through-hole TO-220-7 packaging; the DRV104PWP uses surface-mount 14-PowerTSSOP packaging. PCB layout and assembly process modifications are necessary.

4. Compliance Continuity: Both devices maintain ROHS3 compliance and EAR99 classification, ensuring regulatory alignment for existing supply chains.

Substitution Eligibility Criteria

The DRV104PWP is suitable as a substitute only when:

• Maximum output current requirement does not exceed 1.2A
• Load voltage requirement does not exceed 32V
• Surface-mount assembly capability exists or can be implemented
• Design timeline permits PCB layout modifications

Frequently Asked Questions (FAQ)

Q: Can the DRV104PWP directly replace the DRV102T in existing designs?

A: Direct pin-for-pin replacement is not possible due to different package formats (TO-220-7 through-hole vs. 14-PowerTSSOP surface-mount). PCB redesign is required. Additionally, the DRV104PWP has reduced maximum output current (1.2A vs. 2A) and lower maximum load voltage (32V vs. 60V), which may not meet all application requirements.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are maximum output current (DRV102T: 2A; DRV104PWP: 1.2A) and maximum load voltage (DRV102T: 60V; DRV104PWP: 32V). Both maintain identical 1:1 bipolar output configuration, on/off control interface, internal PWM, status flag output, and identical fault protection mechanisms.

Q: Are there any compliance or certification differences?

A: Both devices are ROHS3 compliant and carry EAR99 classification. The DRV102T has MSL rating 1 (unlimited moisture sensitivity level), while the DRV104PWP has MSL rating 2 (1-year shelf life requirement). This difference affects storage and handling procedures.

Q: What should I verify before implementing the DRV104PWP as a substitute?

A: Verify that your application's maximum output current requirement does not exceed 1.2A and that the maximum load voltage does not exceed 32V. Confirm that surface-mount assembly is available in your manufacturing process. Review the DRV104PWP datasheet for detailed electrical characteristics and timing specifications to ensure functional compatibility with your control circuitry.

Q: Are there other Texas Instruments relay/solenoid driver alternatives?

A: The provided substitute list identifies the DRV104PWP as the manufacturer-recommended equivalent. For applications requiring higher current capability (above 1.2A) or higher load voltage (above 32V), alternative driver architectures from Texas Instruments or other manufacturers may be necessary; however, such alternatives are outside the scope of this direct substitution analysis.
