SLA7050M Equivalent & Substitute Parts

Part Overview

The SLA7050M is a unipolar motor driver IC manufactured by Sanken Electric USA Inc., designed for stepper and brushed DC motor control applications. This device integrates control and power stage functionality in a 18-ZIP package, operating across a 3V to 5.5V supply range with output capability up to 1A. The SLA7050M is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7050M is determined by the following critical parameters:

• Motor Control Type: Unipolar stepper motor driver capability
• Output Configuration: Half Bridge (2) topology
• Interface: Parallel control interface
• Step Resolution: Support for 1 and 1/2 step modes
• Current Rating: 1A output current
• Package: 18-ZIP (18-SSIP Formed Leads)
• Mounting: Through Hole
• Compliance: RoHS Compliant, MSL 1

The SLA7027MU qualifies as a substitute based on matching output configuration, interface type, step resolution, current rating, package form factor, and mounting method. Both devices maintain identical mechanical compatibility and electrical interface requirements for parallel control systems.

Parameter Comparison

Engineering Selection Recommendations

The SLA7027MU is available as an active product with 1746 units in stock, compared to the obsolete SLA7050M status. Both devices maintain RoHS compliance and MSL 1 rating, ensuring equivalent environmental and regulatory qualification. The primary design consideration is the supply voltage range: the SLA7050M operates from 3V to 5.5V, while the SLA7027MU requires 10V to 44V supply. Selection between these devices depends on the control circuit supply voltage available in the target application. For systems operating at 10V or higher, the SLA7027MU provides direct substitution with active product support and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the SLA7027MU directly replace the SLA7050M in existing designs?

A: Mechanical and electrical interface compatibility is confirmed through matching package type (18-ZIP), output configuration (Half Bridge 2), interface method (Parallel), and current rating (1A). The critical design parameter is supply voltage: the SLA7027MU requires minimum 10V supply, whereas the SLA7050M operates from 3V. Direct substitution is possible only if the control circuit supply voltage is 10V or higher.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on motor control type (unipolar stepper), output topology (Half Bridge 2), control interface (Parallel), step resolution support (1 and 1/2), output current (1A), package form factor (18-ZIP), and mounting method (Through Hole). Voltage supply ranges are application-specific and must be evaluated separately.

Q: Are both devices RoHS compliant?

A: Yes. Both the SLA7050M and SLA7027MU are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent environmental and regulatory requirements.

Q: What is the primary difference between these two devices?

A: The SLA7050M operates with a 3V to 5.5V supply range, while the SLA7027MU requires 10V to 44V supply. All other functional and mechanical parameters are equivalent. The SLA7027MU is currently in active production status with available inventory.

Q: Is the 18-ZIP package identical between both parts?

A: Yes. Both devices use the 18-SSIP Formed Leads package (18-ZIP supplier designation), ensuring identical PCB footprint and mounting compatibility.
