SLA7071MPR Equivalent & Substitute Parts

Part Overview

The SLA7071MPR is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. This Power MOSFET-based driver integrates both control and power stages in a single 23-ZIP package, supporting supply voltages from 3V to 5.5V with load voltage capability up to 44V. The part is currently classified as obsolete, which necessitates identification of active equivalent components for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLA7071MPR is based on strict equivalence across the following critical parameters:

• Motor Control Function: Unipolar stepper motor driver with fully integrated control and power stages
• Electrical Specifications: 1.5A output current, 3V–5.5V supply voltage, 10V–44V load voltage capability
• Interface Architecture: Parallel control interface with low-side output configuration (4 channels)
• Mechanical Compatibility: 23-ESIP formed leads package for through-hole mounting
• Regulatory Compliance: RoHS compliance and MSL rating

The SLA7071MPRT is identified as the direct equivalent substitute. Both parts share identical electrical ratings, functional architecture, and package specifications. The primary distinction is product status: SLA7071MPR is obsolete, while SLA7071MPRT is active production.

Parameter Comparison

Engineering Selection Recommendations

The SLA7071MPRT is the direct functional and electrical equivalent of the SLA7071MPR. Selection of SLA7071MPRT is appropriate for new designs and procurement of replacement components, as it maintains active production status with Sanken Electric USA Inc. Both parts carry identical RoHS compliance certification and MSL ratings, ensuring regulatory and environmental compatibility. The transition from SLA7071MPR to SLA7071MPRT involves no electrical or mechanical redesign requirements; pin configuration, package footprint, and electrical performance remain unchanged. The SLA7071MPRT is supplied in tube packaging, which may differ from original procurement specifications but does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can SLA7071MPRT be used as a direct replacement for SLA7071MPR in existing designs?

A: Yes. The SLA7071MPRT is electrically and mechanically identical to the SLA7071MPR. No circuit modifications or PCB redesign is required. Both parts feature the same 23-ESIP package, pin configuration, electrical ratings, and functional specifications.

Q: What is the primary reason for substitution?

A: The SLA7071MPR is classified as obsolete. The SLA7071MPRT is the active production equivalent from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there differences in packaging between the two parts?

A: The SLA7071MPR packaging type is not specified in available documentation. The SLA7071MPRT is supplied in tube packaging. This difference affects handling and storage procedures but does not impact electrical performance or mechanical compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both SLA7071MPR and SLA7071MPRT are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), meeting identical environmental and regulatory requirements.

Q: What are the critical electrical parameters that define substitution compatibility?

A: Substitution is valid when the following parameters match: 1.5A output current, 3V–5.5V supply voltage range, 10V–44V load voltage capability, parallel control interface, low-side output configuration (4 channels), and -20°C to 150°C operating temperature range.

Q: Is the SLA7071MPRT suitable for general-purpose motor control applications?

A: Yes. The SLA7071MPRT is rated for general-purpose applications and supports unipolar stepper motor control with step resolution options of 1 and 1/2 stepping.
