DRV8847RTER Equivalent & Substitute Parts

Part Overview

The DRV8847RTER is an active, fully integrated bipolar motor driver from Texas Instruments designed for brushed DC and stepper motor applications. This Power Management IC combines control and power stage functionality in a compact 16-WQFN (3x3) surface mount package with exposed pad. The device operates across supply voltages of 0V to 5V and supports load voltages from 2.7V to 18V, delivering 2A output current through a half-bridge (4) output configuration with PWM interface control.

Identifying equivalent and substitute parts is necessary to address inventory constraints, procurement lead times, packaging format requirements, and supply chain optimization while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRV8847RTER are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Parameters:

• Motor Type (Bipolar stepper and brushed DC capability)
• Output Configuration (Half Bridge with 4 outputs)
• Interface Protocol (PWM control)
• Output Current Rating (2A)
• Supply Voltage Range (0V ~ 5V)
• Load Voltage Range (2.7V ~ 18V)
• Operating Temperature Range (-40°C ~ 125°C)

Mechanical Parameters:

• Package Type (16-WQFN with exposed pad)
• Physical Dimensions (3x3 mm)
• Mounting Technology (Surface Mount)

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected Status
• MSL Rating (1 - Unlimited)
• Product Status (Active)

Parts are grouped as substitutes only when all parameters listed above match exactly. Packaging format (bulk versus tape & reel) does not affect electrical or mechanical compatibility and represents the only allowable variation within the substitute group.

Parameter Comparison

Engineering Selection Recommendations

The DRV8847RTET is a direct parametric equivalent to the DRV8847RTER. Both devices are manufactured by Texas Instruments, carry Active product status, and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

The only distinction between these parts is packaging format. The DRV8847RTER is supplied in bulk packaging, while the DRV8847RTET is supplied in Tape & Reel (TR) format. This difference does not affect electrical performance, thermal characteristics, or mechanical compatibility on the PCB.

Compliance Alignment:

Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited moisture sensitivity). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001, ensuring regulatory equivalence for procurement and export purposes.

Inventory Considerations:

Selection between these equivalents should be based on procurement requirements, assembly process specifications, and supply chain availability. The DRV8847RTER (bulk) contains 2400 pieces in current inventory, while the DRV8847RTET (tape & reel) contains 1400 pieces.

Frequently Asked Questions (FAQ)

Q: Are the DRV8847RTER and DRV8847RTET electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments using identical Power MOSFET technology, with matching output current (2A), supply voltage (0V ~ 5V), load voltage (2.7V ~ 18V), and operating temperature ranges (-40°C ~ 125°C). They deliver identical performance in bipolar stepper and brushed DC motor driver applications.

Q: What is the difference between DRV8847RTER and DRV8847RTET?

A: The only difference is packaging format. The DRV8847RTER is supplied in bulk packaging, while the DRV8847RTET is supplied in Tape & Reel (TR) format. Both use the same 16-WQFN (3x3) surface mount package with exposed pad.

Q: Can I substitute DRV8847RTET for DRV8847RTER on my PCB?

A: Yes. Both parts have identical mechanical dimensions (16-WQFN 3x3), identical pin configurations, and identical electrical characteristics. PCB layout and assembly compatibility are identical.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (bulk versus tape & reel) is a supply and handling specification only. It does not affect electrical performance, thermal behavior, or mechanical fit on the PCB.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DRV8847RTER and DRV8847RTET are ROHS3 compliant and REACH unaffected, with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I select for high-volume production?

A: For high-volume production, Tape & Reel (TR) packaging is typically preferred for automated assembly processes. The DRV8847RTET in tape & reel format is the standard choice for manufacturing environments with pick-and-place equipment.

Q: Which part should I select for prototyping or low-volume applications?

A: For prototyping or low-volume applications, bulk packaging may be more practical. The DRV8847RTER in bulk format allows for flexible quantities without tape & reel handling requirements.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts share identical thermal specifications, operating temperature ranges (-40°C ~ 125°C), and reliability characteristics. Packaging format does not affect thermal performance or device lifespan.

Q: What is the base product number for both parts?

A: The base product number for both the DRV8847RTER and DRV8847RTET is DRV8847. The suffix letters indicate packaging format and tape configuration.
