SLA7032M Equivalent & Substitute Parts

Part Overview

The SLA7032M is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. It integrates a fully functional control and power stage with Power MOSFET technology, operating across a supply voltage range of 10V to 44V. The device is packaged in an 18-SSIP formed leads configuration and is currently classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7032M is determined by strict alignment with the following critical parameters:

• Motor Type: Unipolar stepper motor driver functionality
• Output Configuration: Half Bridge (2) topology
• Interface: Parallel control interface
• Technology: Power MOSFET implementation
• Step Resolution: Support for 1 and 1/2 step modes
• Current Rating: 1.5A output current capability
• Voltage Range: 10V to 44V supply and load voltage compatibility
• Package: 18-SSIP formed leads through-hole mounting
• Compliance: RoHS compliant status

The SLA7024M meets all specified electrical and mechanical parameters, making it a direct functional equivalent for the obsolete SLA7032M.

Parameter Comparison

Engineering Selection Recommendations

The SLA7024M is the direct substitute for the SLA7032M based on complete electrical and mechanical parameter alignment. The primary distinction is product status: the SLA7032M is obsolete while the SLA7024M maintains active production status. Both devices are RoHS compliant and carry identical export classification (EAR99) and tariff codes (8542.39.0001), ensuring regulatory consistency in design transitions. The SLA7024M's active availability provides supply chain continuity for new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can the SLA7024M directly replace the SLA7032M in existing designs?

A: Yes. The SLA7024M is electrically and mechanically identical to the SLA7032M across all specified parameters, including voltage range (10V–44V), output current (1.5A), step resolution (1, 1/2), package configuration (18-SSIP), and interface type (parallel). No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The SLA7032M is classified as obsolete. The SLA7024M, with identical specifications, is in active production and provides assured supply availability.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant, carry MSL rating 1 (unlimited moisture sensitivity), and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Does the package form factor remain the same?

A: Yes. Both devices use the 18-SSIP formed leads package with through-hole mounting, ensuring PCB layout compatibility without redesign.

Q: Are there operating temperature differences?

A: The SLA7032M specifies an operating temperature range of -20°C to 150°C (TJ). The SLA7024M operating temperature is not specified in the provided data. Verify thermal requirements against your application specifications before final selection.
