SLA7077MPR Equivalent & Substitute Parts

Part Overview

The SLA7077MPR 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 SLA7077MPR is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7077MPR is determined by strict alignment across the following critical parameters: motor type classification (unipolar stepper), functional integration level (fully integrated control and power stage), output configuration (low side with 4 outputs), interface type (parallel), technology platform (power MOSFET), step resolution capability (1, 1/2, 1/4, 1/8, 1/16), supply voltage range (3V ~ 5.5V), load voltage range (10V ~ 44V), operating temperature range (-20°C ~ 150°C TJ), mounting type (through hole), and package specification (23-ESIP formed leads / 23-ZIP SLA).

Output current rating is not a limiting factor for substitution eligibility; parts with equal or higher current capacity are acceptable alternatives. Packaging format (tube vs. other formats) does not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

SLA7077MPRT is the direct functional equivalent to the obsolete SLA7077MPR. Both parts share identical electrical specifications, mechanical packaging, and operational parameters. The SLA7077MPRT maintains active product status with ROHS3 compliance certification, providing long-term availability and supply chain continuity.

SLA7076MPRT is a parametric equivalent classified by reduced output current specification (1.5A versus 2A). This part is suitable for applications where motor load current requirements do not exceed 1.5A. The SLA7076MPRT maintains all other critical parameters including supply voltage, load voltage, step resolution, and thermal operating range. Selection of SLA7076MPRT requires verification that application motor current demands remain within the 1.5A output limit.

Frequently Asked Questions (FAQ)

Q: Can SLA7077MPRT directly replace SLA7077MPR in existing designs?

A: Yes. SLA7077MPRT is functionally identical to SLA7077MPR across all electrical and mechanical parameters. The primary difference is product status (active versus obsolete) and packaging format (tube). No design modifications are required.

Q: What is the difference between SLA7077MPRT and SLA7076MPRT?

A: The primary difference is output current rating. SLA7077MPRT provides 2A output current, while SLA7076MPRT provides 1.5A. All other parameters including supply voltage, load voltage, step resolution, package, and thermal range are identical. Selection depends on application motor current requirements.

Q: Can SLA7076MPRT be used in place of SLA7077MPR?

A: SLA7076MPRT is suitable only if application motor current requirements do not exceed 1.5A. The reduced current specification makes this part a parametric equivalent rather than a direct replacement. Verify motor load current specifications before selection.

Q: Are there packaging differences between these parts?

A: SLA7077MPR is supplied in standard packaging format. SLA7077MPRT and SLA7076MPRT are supplied in tube packaging. All three parts use identical 23-ESIP formed leads with 23-ZIP (SLA) supplier device package specification. Tube packaging does not affect functional performance or PCB mounting compatibility.

Q: What compliance certifications apply to these parts?

A: SLA7077MPR and SLA7076MPRT carry RoHS Compliant certification. SLA7077MPRT carries ROHS3 Compliant certification. All three parts have Moisture Sensitivity Level 1 (Unlimited). ECCN classification is EAR99 for all parts.
