Substitute Part Grouping Explanation

Substitution eligibility for the DRV8428PRTER is determined by strict equivalence across the following critical parameters:

• Motor Control Capability: Bipolar stepper motor driver with brushed DC motor support
• Output Stage Architecture: Half Bridge (2) configuration with fully integrated control and power stage
• Electrical Specifications: 1A output current, 4.2V to 33V supply voltage range, -40°C to 125°C operating temperature
• Interface Standard: PWM control interface
• Package Specification: 16-WQFN (3x3) with exposed pad, surface mount configuration
• Tape & Reel Packaging: Standard production packaging format

The DRV8428ERTER meets all substitution criteria as a parametric equivalent, maintaining identical electrical performance, motor control functionality, and physical package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the DRV8428PRTER and DRV8428ERTER are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on compliance and regulatory status:

DRV8428PRTER is suitable for applications where RoHS compliance is not a requirement or where the product status of "Not applicable" is acceptable for the end application.

DRV8428ERTER is the appropriate selection for applications requiring RoHS3 compliance and REACH unaffected status. This part carries explicit regulatory certifications and is recommended for new designs targeting compliance-mandated markets and industries.

Both parts maintain identical moisture sensitivity level (MSL 1 - Unlimited), ECCN classification (EAR99), and HTSUS coding, ensuring equivalent handling, storage, and export compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Are DRV8428PRTER and DRV8428ERTER electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including 1A output current, 4.2V to 33V supply voltage range, PWM interface, and -40°C to 125°C operating temperature. They perform identically in circuit applications.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use the identical 16-WQFN (3x3) package with exposed pad in surface mount configuration. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: What is the difference between DRV8428PRTER and DRV8428ERTER?

A: The primary difference is regulatory compliance status. DRV8428ERTER carries RoHS3 compliance and REACH unaffected certification, while DRV8428PRTER does not have these designations. Both parts are functionally and mechanically identical.

Q: Which part should be selected for new product designs?

A: DRV8428ERTER is recommended for new designs due to its explicit RoHS3 compliance and REACH unaffected status, ensuring alignment with current regulatory requirements in most markets.

Q: Are there any differences in packaging or tape & reel specifications?

A: No. Both parts are supplied in identical Tape & Reel (TR) packaging format with standard moisture sensitivity level MSL 1 (Unlimited).

Q: Can DRV8428ERTER be used as a direct replacement in existing designs using DRV8428PRTER?

A: Yes. The DRV8428ERTER is a direct parametric equivalent and can be substituted without circuit modifications, PCB redesign, or firmware changes.

Q: What motor types are supported by these drivers?

A: Both parts support bipolar stepper motors and brushed DC motors with 1A output current capability through dual half-bridge output configuration.
