SLA7031M Equivalent & Substitute Parts

Part Overview

The SLA7031M is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. This device integrates both control and power stages in a single package, operating across a 10V to 44V supply range with 1A output current capability. The SLA7031M is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7031M is determined by strict alignment across the following critical parameters:

Motor control architecture (unipolar stepper driver with fully integrated control and power stages), output configuration (half bridge topology with 2 outputs), interface type (parallel control), power MOSFET technology, step resolution capability (1 and 1/2 stepping), output current rating (1A), supply and load voltage range (10V to 44V), through-hole mounting, 18-SSIP package format, and regulatory compliance (RoHS Compliant, MSL 1).

The SLA7027MU meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete SLA7031M.

Parameter Comparison

Engineering Selection Recommendations

The SLA7027MU is the appropriate substitute for the obsolete SLA7031M. Both devices are manufactured by Sanken Electric USA Inc. and maintain identical electrical specifications, output configuration, and package format. The SLA7027MU carries active product status, ensuring ongoing availability and manufacturing support. Both parts maintain RoHS compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The through-hole 18-ZIP package format is consistent between both parts, allowing direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SLA7027MU be used as a direct replacement for the SLA7031M?

A: Yes. The SLA7027MU is electrically and mechanically equivalent to the SLA7031M. Both devices feature identical unipolar stepper motor driver architecture, 1A output current, 10V to 44V supply range, half-bridge output configuration, parallel interface, and 18-SSIP through-hole packaging.

Q: What is the primary reason to transition from SLA7031M to SLA7027MU?

A: The SLA7031M is classified as obsolete. The SLA7027MU is an active product with ongoing manufacturing support and availability, making it the recommended choice for new designs and ongoing procurement.

Q: Are there any package or pinout differences between these parts?

A: No. Both the SLA7031M and SLA7027MU use the 18-SSIP formed leads package with 18-ZIP supplier device package designation. Pinout and footprint compatibility are maintained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SLA7031M and SLA7027MU are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent regulatory and environmental requirements.

Q: Are there operating temperature differences between the two parts?

A: The SLA7031M specifies an operating temperature range of -20°C to 150°C (TJ). Operating temperature data for the SLA7027MU is not provided in the available specifications.
