DRV101TG3 Equivalent & Substitute Parts

Part Overview

The DRV101TG3 is a Power Management IC (PMIC) classified as a Power Switch/Driver with 1:1 bipolar output configuration, rated for 1.9A maximum output current. Designed for relay and solenoid driver applications, this component operates across a load voltage range of 9V to 60V with an operating temperature range of -55°C to 125°C. The device features internal PWM capability, status flag output, and integrated fault protection including current limiting and over-temperature protection.

The DRV101TG3 is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRV101TG3 is determined by the following critical parameters:

• Switch Type & Application: Relay and solenoid driver functionality
• Output Configuration: Low side driver topology
• Input:Output Ratio: 1:1 configuration
• Interface Type: On/Off control
• Fault Protection: Current limiting and over-temperature protection
• Features: Internal PWM and status flag capability
• Operating Temperature Range: -55°C to 125°C
• Compliance: ROHS3 compliance and MSL Level 1

The DRV103H qualifies as a manufacturer-recommended substitute. While it differs in output type (N-Channel versus Bipolar), mounting technology (Surface Mount versus Through Hole), and electrical ratings (3A output current and 8V–32V load voltage versus 1.9A and 9V–60V), it maintains functional equivalence in core driver topology, control interface, protection features, and temperature range. The higher current rating and lower voltage range of the DRV103H represent design improvements suitable for applications within its specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

The DRV103H is designated as the manufacturer-recommended substitute for the obsolete DRV101TG3. Both components maintain ROHS3 compliance and MSL Level 1 classification, ensuring equivalent environmental and regulatory standing.

Selection of the DRV103H requires verification that the application load voltage does not exceed 32V, as the substitute part's maximum load voltage rating is lower than the original part. The DRV103H's higher maximum output current (3A versus 1.9A) provides additional design margin for applications within the specified voltage envelope.

The transition from Through Hole (TO-220-7) to Surface Mount (8-PowerSOIC) packaging necessitates PCB layout and assembly process modifications. Both components provide identical control interface topology, internal PWM functionality, and fault protection mechanisms, supporting functional equivalence in driver applications.

Frequently Asked Questions (FAQ)

Q: Can the DRV103H directly replace the DRV101TG3 in all applications?

A: The DRV103H is functionally equivalent for relay and solenoid driver applications within its specified electrical ratings. Applications requiring load voltages above 32V must retain the DRV101TG3 or identify alternative solutions. PCB layout modifications are required due to packaging differences (Through Hole versus Surface Mount).

Q: What are the key differences between the DRV101TG3 and DRV103H?

A: The primary differences are output type (Bipolar versus N-Channel), maximum load voltage (9V–60V versus 8V–32V), maximum output current (1.9A versus 3A), mounting technology (Through Hole versus Surface Mount), and product status (Obsolete versus Active). Core functionality including 1:1 ratio, low-side configuration, On/Off interface, internal PWM, status flag, and fault protection remain identical.

Q: Are there packaging considerations for substitution?

A: Yes. The DRV101TG3 uses TO-220-7 Through Hole packaging, while the DRV103H uses 8-PowerSOIC Surface Mount packaging. PCB redesign, assembly process changes, and thermal management evaluation may be necessary. Verify that the 8-PowerSOIC footprint and thermal characteristics are compatible with the target application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DRV101TG3 and DRV103H are ROHS3 compliant with MSL Level 1 classification. Both are REACH unaffected and classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the voltage limitation when using the DRV103H?

A: The DRV103H is rated for load voltages between 8V and 32V. Applications requiring operation above 32V cannot use this substitute and must identify alternative components or retain the original DRV101TG3 if available.
