DRV102TG3 Equivalent & Substitute Parts

Part Overview

The DRV102TG3 is a power switch/driver IC manufactured by Texas Instruments, designed for relay and solenoid driving applications with 1:1 input-to-output ratio and high-side bipolar output configuration. This component operates across a load voltage range of 8V to 60V with a maximum output current of 2A and includes internal PWM capability and status flag features. The DRV102TG3 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DRV102TG3 is determined by the following core parameters:

• Switch Type & Application: Relay and solenoid driver functionality
• Output Configuration: High-side, 1:1 ratio, non-inverting input
• Load Voltage Range: Minimum 8V support required
• Output Current Capability: Minimum 1.2A required for functional compatibility
• Interface Type: On/Off control with internal PWM and status flag
• Fault Protection: Current limiting and over-temperature protection
• Operating Temperature Range: -55°C to 125°C
• Compliance: ROHS3 compliant, REACH unaffected

The DRV104PWP meets these core substitution criteria while operating within the specified electrical and thermal parameters. Differences in maximum load voltage (32V vs. 60V) and output current (1.2A vs. 2A) represent functional constraints that must be evaluated against specific application requirements.

Engineering Selection Recommendations

The DRV104PWP is the manufacturer-recommended substitute for the obsolete DRV102TG3. Both components maintain identical compliance certifications (ROHS3, REACH unaffected) and share core functional characteristics including 1:1 ratio, high-side output configuration, internal PWM, and status flag capability.

Selection of the DRV104PWP requires verification that application load voltage does not exceed 32V and output current demand does not exceed 1.2A. The transition from through-hole TO-220-7 to surface-mount 14-PowerTSSOP packaging necessitates PCB layout redesign.

The active product status of DRV104PWP ensures ongoing manufacturer support, availability, and compliance with current industry standards, making it the appropriate choice for new designs and legacy system updates where electrical parameters align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the DRV104PWP directly replace the DRV102TG3 without circuit modification?

A: Functional substitution is possible if application load voltage remains within 8V to 32V and output current does not exceed 1.2A. PCB layout modification is required due to package change from TO-220-7 through-hole to 14-PowerTSSOP surface-mount.

Q: What are the critical parameter differences between these parts?

A: Maximum load voltage is reduced from 60V to 32V, and maximum output current is reduced from 2A to 1.2A. All other electrical characteristics, including input-to-output ratio, output configuration, protection features, and operating temperature range, remain equivalent.

Q: Why is the DRV102TG3 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The DRV104PWP represents the active alternative within the Texas Instruments power driver product line.

Q: Are there packaging considerations for substitution?

A: Yes. The DRV102TG3 uses through-hole TO-220-7 packaging, while the DRV104PWP uses surface-mount 14-PowerTSSOP packaging. This requires PCB redesign and different assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DRV102TG3 and DRV104PWP are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory compliance.
