SLA7022MU Equivalent & Substitute Parts

Part Overview

The SLA7022MU 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 in a 15-ZIP package. The device operates across a supply voltage range of 10V to 44V with 1A output current capability and half-bridge output configuration.

The SLA7022MU is classified as obsolete. Identifying equivalent and substitute parts is essential for design continuity, system maintenance, and procurement planning when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLA7022MU is determined by strict alignment of the following critical parameters:

• Motor Type (Stepper): Unipolar
• Function: Driver - Fully Integrated, Control and Power Stage
• Output Configuration: Half Bridge (2)
• Interface: Parallel
• Technology: Power MOSFET
• Current - Output: 1A
• Voltage - Supply: 10V ~ 44V
• Voltage - Load: 10V ~ 44V
• Mounting Type: Through Hole
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SLA7027MU meets all critical substitution criteria. While it features an 18-ZIP package (compared to the 15-ZIP of the original), it maintains identical electrical specifications, voltage ratings, current capacity, and compliance certifications. The package difference reflects an expanded pin count for additional functionality, but the core driver characteristics remain compatible for unipolar stepper motor applications.

Parameter Comparison

Engineering Selection Recommendations

The SLA7027MU is the qualified substitute for the SLA7022MU based on the following criteria:

Electrical Compatibility: Both devices maintain identical voltage supply ranges (10V ~ 44V), load voltage ratings (10V ~ 44V), and output current specifications (1A). The unipolar stepper motor driver architecture, half-bridge output configuration, and parallel interface are preserved across both parts.

Compliance and Certification: Both the SLA7022MU and SLA7027MU carry RoHS Compliant status and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance for industrial and commercial applications.

Product Status: The SLA7027MU is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete SLA7022MU.

Package Consideration: The SLA7027MU uses an 18-ZIP package versus the 15-ZIP of the original part. PCB layout modifications are required to accommodate the different pin count and physical dimensions. Through-hole mounting compatibility is maintained for both devices.

Frequently Asked Questions (FAQ)

Q: Can the SLA7027MU directly replace the SLA7022MU without circuit modifications?

A: Electrical substitution is valid based on identical voltage ratings, current capacity, and driver function. However, the package difference (18-ZIP versus 15-ZIP) requires PCB layout redesign. Pin-to-pin correspondence must be verified against manufacturer datasheets before implementation.

Q: What is the primary difference between the SLA7022MU and SLA7027MU?

A: The SLA7027MU features an expanded 18-ZIP package compared to the 15-ZIP package of the SLA7022MU. Both devices deliver identical electrical performance for unipolar stepper motor control applications. The additional pins in the SLA7027MU support extended functionality options.

Q: Are there compliance or certification differences between these parts?

A: No. Both the SLA7022MU and SLA7027MU maintain identical RoHS Compliance status and MSL Level 1 ratings. Regulatory and environmental compliance requirements are equivalent.

Q: Why is the SLA7022MU classified as obsolete?

A: The SLA7022MU has reached end-of-life status. The SLA7027MU represents the active successor product line from Sanken Electric USA Inc. for unipolar stepper motor driver applications.

Q: What mounting considerations apply to the SLA7027MU?

A: Both devices use through-hole mounting technology. The SLA7027MU maintains formed leads for standard PCB assembly processes. Physical footprint differences due to the 18-ZIP package require updated PCB design files and assembly documentation.
