SLA7078MPR Equivalent & Substitute Parts

Part Overview

The SLA7078MPR is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. This device integrates a fully functional control and power stage with low-side output configuration, operating across a 3V to 5.5V supply voltage range with load voltage capability from 10V to 44V.

The SLA7078MPR is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7078MPR is determined by strict equivalence across the following critical parameters:

Motor driver type and control architecture (unipolar stepper motor driver with fully integrated control and power stage), output configuration (low-side, 4-channel), interface topology (parallel), power MOSFET technology, step resolution capability (1, 1/2, 1/4, 1/8, 1/16), output current rating (3A), 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 format, and RoHS compliance status.

Only parts matching all these parameters across the specified ranges are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

The SLA7078MPRT is a parametric equivalent to the SLA7078MPR. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: the SLA7078MPR is obsolete while the SLA7078MPRT maintains active production status.

For new designs or production requiring component continuity, the SLA7078MPRT is the appropriate selection. Both parts are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity), ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the SLA7078MPRT directly replace the SLA7078MPR in existing designs?

A: Yes. The SLA7078MPRT is a parametric equivalent with identical electrical and mechanical specifications. No design modifications are required for direct substitution.

Q: What is the significance of the product status difference between these parts?
