SLA7072MPRT Equivalent & Substitute Parts

Part Overview

The SLA7072MPRT is an active, RoHS-compliant unipolar stepper motor driver manufactured by Sanken Electric USA Inc. This integrated power management IC combines control and power stage functionality in a 23-ESIP through-hole package, designed for general-purpose motor control applications operating between 3V and 5.5V supply voltage with load voltage capability up to 44V. The device delivers 2A output current across four low-side driver channels with configurable step resolution (1 or 1/2 step modes). Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The SLA7071MPRT qualifies as a parametric equivalent based on the following alignment criteria:

Matching Parameters:

• Motor type classification (Unipolar stepper)
• Integrated driver function with control and power stage
• Four low-side output configuration
• Parallel interface architecture
• Power MOSFET technology
• Step resolution capability (1, 1/2)
• Supply voltage range (3V ~ 5.5V)
• Load voltage range (10V ~ 44V)
• Operating temperature range (-20°C ~ 150°C TJ)
• Through-hole mounting
• 23-ESIP package form factor
• RoHS compliance
• MSL rating (1 - Unlimited)

Differentiating Parameter:

• Output current: SLA7072MPRT rated at 2A; SLA7071MPRT rated at 1.5A

The SLA7071MPRT operates within the same electrical and mechanical envelope as the SLA7072MPRT with reduced maximum output current capacity. Substitution is valid when application current requirements do not exceed 1.5A per channel.

Parameter Comparison

Engineering Selection Recommendations

Both the SLA7072MPRT and SLA7071MPRT maintain active product status and full RoHS compliance with unlimited moisture sensitivity level rating. Selection between these parts is determined by application current requirements:

SLA7072MPRT is the primary choice for applications requiring maximum output current of 2A per channel.

SLA7071MPRT is suitable for applications where motor coil current does not exceed 1.5A per channel, offering an alternative with equivalent electrical characteristics and identical package footprint.

Both devices are through-hole mounted in the 23-ESIP form factor, ensuring direct PCB compatibility without layout modification. Compliance certifications (RoHS, ECCN EAR99, HTSUS 8542.39.0001) are identical across both parts.

Frequently Asked Questions (FAQ)

Q: Can the SLA7071MPRT directly replace the SLA7072MPRT in an existing design?

A: Direct replacement is possible only if the application motor current requirement does not exceed 1.5A per channel. The SLA7071MPRT has identical pinout, package footprint, and electrical interface characteristics. No PCB modification is required. If the design requires 2A output current, the SLA7072MPRT must be used.

Q: Are there any differences in control logic or interface between these parts?

A: No. Both devices use parallel interface architecture with identical control and power stage integration. Step resolution modes (1 and 1/2 step) are supported on both parts. The only functional difference is maximum output current rating.

Q: Do these parts have the same supply and load voltage specifications?

A: Yes. Both the SLA7072MPRT and SLA7071MPRT operate with 3V to 5.5V supply voltage and support load voltages from 10V to 44V. Operating temperature range is identical at -20°C to 150°C junction temperature.

Q: What is the significance of the packaging difference (bulk vs. tube)?

A: The SLA7072MPRT is supplied in bulk packaging, while the SLA7071MPRT is supplied in tube packaging. This affects handling and storage procedures but does not impact electrical performance or compatibility. Both are through-hole mounted components with identical MSL rating (1 - Unlimited).

Q: Are both parts suitable for general-purpose motor control applications?

A: Yes. Both the SLA7072MPRT and SLA7071MPRT are classified for general-purpose applications. The distinction is output current capacity. Applications requiring stepper motor control within the 1.5A per-channel limit can use either part interchangeably from a functional standpoint.
