Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7073MPR 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), and power MOSFET technology form the functional foundation for substitution.

Electrical specifications must match exactly: 3A output current, 3V to 5.5V supply voltage range, 10V to 44V load voltage range, and -20°C to 150°C operating temperature range.

Mechanical compatibility requires identical package type (23-ESIP Formed Leads) and mounting method (through-hole).

Compliance certifications (RoHS status) and moisture sensitivity classification (MSL 1) must be maintained or improved.

Parameter Comparison

Engineering Selection Recommendations

The SLA7073MPRT is a direct functional equivalent to the SLA7073MPR. Both devices share identical electrical specifications, mechanical packaging, and core functionality as unipolar stepper motor drivers with fully integrated control and power stages.

The primary distinction is product lifecycle status: the SLA7073MPR is obsolete, while the SLA7073MPRT maintains active production status. The SLA7073MPRT also carries ROHS3 compliance, representing an updated regulatory certification compared to the RoHS compliance of the original part.

For new designs or component replenishment, the SLA7073MPRT is the appropriate selection. Both parts are functionally interchangeable within applications designed for the SLA7073 base product architecture.
