DRV8886RHRT Equivalent & Substitute Parts

Part Overview

The DRV8886RHRT is a bipolar stepper motor driver IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This fully integrated driver combines control and power stage functionality in a 28-WQFN surface mount package with exposed pad. The device operates with supply voltages from 0V to 5.3V and supports load voltages from 8V to 37V, delivering 2A output current with step resolution from 1 to 1/16. The part is Active status and RoHS3 compliant, suitable for general-purpose motor control applications. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and functional requirements.

These substitutes maintain package compatibility and core functional architecture while varying in internal technology and output current specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and RoHS3 compliance, ensuring long-term availability and regulatory conformance equivalent to the DRV8886RHRT.

For applications requiring 2A output current: Select from DRV8886ATRHRT, DRV8886ATRHRR, or DRV8886RHRR. These parts maintain identical Power MOSFET technology and output specifications as the primary part. DRV8886ATRHRT and DRV8886ATRHRR offer higher inventory availability (5798 and 3200 units respectively) compared to the primary part (822 units).

For applications tolerating 1.5A output current: DRV8885RHRT and DRV8885RHRR are suitable alternatives. These parts employ NMOS technology instead of Power MOSFET and deliver reduced output current. DRV8885RHRR provides the highest inventory availability at 4042 units.

All substitutes share identical package footprint, supply voltage range, load voltage range, operating temperature range, and step resolution specifications, ensuring direct mechanical and electrical compatibility within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can DRV8885 series parts directly replace DRV8886 series parts?

A: DRV8885 parts are compatible substitutes only when the application can operate with 1.5A output current instead of 2A. Both series maintain identical package footprint (28-WQFN 5.5x4.6), voltage ranges (supply 0V-5.3V, load 8V-37V), and operating temperature range (-40°C to 125°C). The primary difference is output current capability and internal technology (NMOS vs. Power MOSFET).

Q: What is the difference between DRV8886RHRT and DRV8886RHRR?

A: Both parts are identical in electrical specifications and package. The suffix difference (RHRT vs. RHRR) indicates different tape and reel configurations for automated assembly. Selection between these variants depends on your manufacturing process requirements, not electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including DRV8886ATRHRT, DRV8886ATRHRR, DRV8886RHRR, DRV8885RHRT, and DRV8885RHRR, are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the DRV8886RHRT.

Q: Which substitute part has the best inventory availability?

A: DRV8886ATRHRT offers the highest inventory at 5798 units, followed by DRV8885RHRR at 4042 units. Both maintain full electrical and mechanical compatibility with the primary part within their respective technology groups.

Q: Can I use DRV8886ATRHRT as a direct pin-for-pin replacement?

A: Yes. DRV8886ATRHRT maintains identical pinout, package footprint (28-WQFN 5.5x4.6), and electrical specifications (2A output, Power MOSFET technology, 0V-5.3V supply, 8V-37V load voltage) as the DRV8886RHRT, enabling direct substitution without circuit modification.
