Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC17529EJR2 is determined by the following critical parameters:

• Motor driver type and output configuration (Half Bridge with 4 outputs for bipolar/brushed DC motor control)
• Parallel interface for control signals
• Package compatibility (20-TSSOP with exposed pad)
• Surface mount mounting type
• Output current capability (minimum 700mA)
• Supply voltage range compatibility
• Operating temperature range
• RoHS3 compliance and regulatory status

The A4990KLPTR-T qualifies as a substitute based on matching motor driver architecture, output configuration, interface type, and package form factor. Both devices support bipolar stepper and brushed DC motor applications with fully integrated control and power stages in identical 20-TSSOP packaging.

Parameter Comparison

Engineering Selection Recommendations

The A4990KLPTR-T is an active substitute for the obsolete MPC17529EJR2. Both devices share identical package geometry, output configuration, and motor driver architecture, enabling direct replacement in 20-TSSOP surface mount applications.

The A4990KLPTR-T offers extended supply voltage range (0V ~ 50V versus 2.7V ~ 5.6V) and increased output current capability (800mA versus 700mA), providing design flexibility for applications requiring higher voltage or current margins. The substitute maintains ROHS3 compliance and extends the operating temperature range to -40°C, supporting broader environmental conditions.

The A4990KLPTR-T carries automotive grade qualification, indicating enhanced reliability and process control suitable for mission-critical applications. Selection should be based on specific voltage and current requirements of the target application, with consideration for the extended electrical specifications of the substitute device.

Frequently Asked Questions (FAQ)

Q: Can the A4990KLPTR-T directly replace the MPC17529EJR2 in existing designs?

A: Yes. Both devices use identical 20-TSSOP package geometry with exposed pad, matching pinout for parallel interface control, and equivalent half-bridge output configuration. PCB layout and footprints require no modification.

Q: What are the key electrical differences between these devices?

A: The A4990KLPTR-T supports wider supply voltage range (0V ~ 50V versus 2.7V ~ 5.6V) and higher output current (800mA versus 700mA). The substitute uses DMOS technology compared to CMOS in the original device. Both maintain identical operating temperature maximum of 150°C, though the substitute extends minimum temperature to -40°C.

Q: Are there any design considerations when switching to the A4990KLPTR-T?

A: Designs operating within the original MPC17529EJR2 voltage range (2.7V ~ 5.6V) and current requirements (≤700mA) require no circuit modifications. Applications utilizing the extended voltage or current capabilities of the A4990KLPTR-T may benefit from design optimization but are not required to change existing implementations.

Q: What is the moisture sensitivity level difference?

A: The MPC17529EJR2 has MSL 3 (168 Hours), while the A4990KLPTR-T has MSL 2 (1 Year). The substitute offers improved moisture tolerance, reducing handling and storage constraints.

Q: Are both devices RoHS compliant?

A: Yes. Both the MPC17529EJR2 and A4990KLPTR-T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
