DRV101F/500 Equivalent & Substitute Parts

Part Overview

The DRV101F/500 is a Power Management IC (PMIC) classified as a power switch/driver for relay and solenoid applications. Manufactured by Texas Instruments, this component operates as a 1:1 bipolar driver with low-side output configuration, rated for 1.9A maximum output current and load voltages between 9V and 60V. The device is currently marked as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRV101F/500 is based on the following critical parameters that define functional equivalence:

• 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
• Operating Temperature Range: -55°C ~ 125°C
• Compliance: ROHS3 compliance and EAR99 classification

The DRV103H qualifies as a substitute based on these core parameters. However, the following differences must be noted: the DRV103H uses N-Channel output type (versus bipolar in the original), operates at a reduced maximum load voltage range (8V ~ 32V versus 9V ~ 60V), and provides higher output current capability (3A versus 1.9A). These differences define the scope of application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DRV103H is the manufacturer-recommended substitute for the obsolete DRV101F/500. Both devices maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency. The DRV103H carries active product status, providing long-term availability and supply chain stability compared to the obsolete DRV101F/500.

Selection of the DRV103H requires validation against the specific load voltage and current requirements of the application. Designs operating within the DRV103H's load voltage range (8V ~ 32V) and requiring output currents up to 3A are directly compatible. Designs requiring load voltages exceeding 32V or utilizing the bipolar output characteristics of the original device require alternative evaluation.

The DRV103H features improved moisture sensitivity (MSL 1 versus MSL 3), reducing handling and storage constraints. Package differences (8-PowerSOIC versus TO-263-8) necessitate PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the DRV103H directly replace the DRV101F/500 in all applications?

A: Direct replacement is valid only for applications where the load voltage does not exceed 32V. The DRV101F/500 supports load voltages up to 60V, while the DRV103H is rated to 32V maximum. Applications requiring higher load voltages require alternative component selection.

Q: What is the significance of the output type difference (Bipolar vs. N-Channel)?

A: The DRV101F/500 uses bipolar output, while the DRV103H uses N-Channel output. This represents a fundamental difference in output stage topology. Bipolar drivers can source and sink current, while N-Channel drivers sink current only. Circuit designs must accommodate this functional difference.

Q: Are there package compatibility considerations?

A: Yes. The DRV101F/500 uses TO-263-8 (D2PAK) packaging, while the DRV103H uses 8-PowerSOIC packaging. These packages have different footprints and pin configurations. PCB redesign is required for physical and electrical compatibility.

Q: Does the higher output current rating of the DRV103H (3A vs. 1.9A) affect compatibility?

A: Higher output current capability does not create incompatibility. Applications designed for 1.9A operation remain within the DRV103H's 3A rating. The increased current capability provides design margin but does not alter functional compatibility for existing applications.

Q: What is the impact of the MSL rating difference?

A: The DRV103H has MSL 1 (unlimited moisture exposure), while the DRV101F/500 has MSL 3 (168-hour limit). This means the DRV103H has less stringent moisture handling requirements during storage and assembly, reducing logistics and manufacturing constraints.
