DRV103UG4 Equivalent & Substitute Parts

Part Overview

The DRV103UG4 is a power switch/driver IC manufactured by Texas Instruments, designed for relay and solenoid driving applications. It features a 1:1 N-channel low-side output configuration with 1.5A maximum output current and operates across a load voltage range of 8V to 32V. The device integrates internal PWM capability and status flag monitoring, with built-in current limiting and over-temperature protection.

The DRV103UG4 is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for seamless integration into existing designs.

Substitute Part Grouping Explanation

Substitution of the DRV103UG4 is determined by strict equivalence across the following critical parameters:

  • Output current rating: 1.5A maximum
  • Load voltage range: 8V ~ 32V
  • Output configuration: Low-side N-channel
  • Input interface: On/Off non-inverting
  • Integrated features: Internal PWM and status flag
  • Protection mechanisms: Current limiting and over-temperature shutdown
  • Package type: 8-SOIC surface mount
  • Operating temperature range: -55°C ~ 125°C
  • Compliance standards: ROHS3, MSL 2

The DRV103U qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is product status and packaging format, with DRV103U currently active in inventory.

Engineering Selection Recommendations

The DRV103U is the manufacturer-recommended substitute for the discontinued DRV103UG4. Both components share identical electrical specifications, thermal operating range, and mechanical packaging. The DRV103U maintains active product status with established supply chain availability, ensuring continuity for new designs and production requirements.

Both parts comply with ROHS3 standards and carry equivalent moisture sensitivity ratings. The substitution requires no circuit modifications, PCB layout changes, or firmware adjustments. Pin-for-pin compatibility is maintained across all signal and power connections.

Frequently Asked Questions (FAQ)

Q: Can DRV103U directly replace DRV103UG4 without circuit modifications?

A: Yes. The DRV103U is electrically and mechanically identical to the DRV103UG4. No schematic, PCB layout, or firmware changes are required for substitution.

Q: What is the difference between DRV103UG4 and DRV103U?

A: The primary difference is product status and packaging format. DRV103UG4 is discontinued; DRV103U is active. Both share identical electrical ratings, output current (1.5A), load voltage range (8V–32V), and 8-SOIC package specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and identical MSL 2 moisture sensitivity ratings. No additional qualification or testing is required for substitution.

Q: What is the 8-SOIC package specification?

A: The 8-SOIC package is a surface-mount small-outline integrated circuit with 8 pins, measuring 0.154 inches (3.90mm) in width. This package type is standard for both the main part and substitute.

Q: Is the DRV103U available in the same packaging format?

A: The DRV103U is supplied in tube packaging, whereas DRV103UG4 packaging details were not specified. Both use identical 8-SOIC component packaging for PCB mounting.
