SLA7073MS Equivalent & Substitute Parts

Part Overview

The SLA7073MS is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. This component 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 SLA7073MS is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, maintenance, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA7073MS is determined by strict alignment across the following critical parameters:

Motor driver function and control architecture (unipolar stepper motor driver with fully integrated control and power stage), output configuration (low-side, 4-channel), interface type (parallel), and power MOSFET technology form the functional foundation for substitution.

Electrical specifications must match: 3A output current, 3V to 5.5V supply voltage range, and 10V to 44V load voltage capability. Step resolution support (1 and 1/2 stepping) must be maintained.

Physical compatibility requires through-hole mounting and 23-ZIP package family designation. RoHS3 compliance and MSL Level 1 certification must be preserved.

The SLA7073MPRT meets all substitution criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The SLA7073MPRT is the direct substitute for the SLA7073MS. Both components share identical electrical specifications, functional architecture, and compliance certifications. The SLA7073MPRT maintains ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility.

The primary advantage of the SLA7073MPRT is its active product status, providing assured long-term availability and supply chain stability compared to the obsolete SLA7073MS. The extended operating temperature range (-20°C to 150°C junction temperature versus -20°C to 85°C ambient temperature) provides additional thermal margin for demanding applications.

Package designation differences (23-SSIP Exposed Tab versus 23-ESIP Formed Leads) represent minor mechanical variations within the 23-ZIP family. Both maintain through-hole mounting compatibility and identical electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the SLA7073MPRT directly replace the SLA7073MS in existing designs?

A: Yes. Both components share identical electrical specifications, output current rating (3A), supply voltage range (3V to 5.5V), load voltage capability (10V to 44V), and step resolution support (1 and 1/2 stepping). Functional and electrical compatibility is complete.

Q: What is the difference between the 23-SSIP and 23-ESIP package designations?

A: Both designations refer to variants within the 23-ZIP package family. The primary difference is in lead formation and tab configuration. Both maintain through-hole mounting compatibility and identical pin assignments for this motor driver application.

Q: Why is the SLA7073MPRT listed with a higher operating temperature range?

A: The SLA7073MS specifies -20°C to 85°C ambient temperature (TA), while the SLA7073MPRT specifies -20°C to 150°C junction temperature (TJ). Junction temperature represents the actual die temperature and provides a more comprehensive thermal specification. The SLA7073MPRT offers extended thermal capability without compromising electrical performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SLA7073MS and SLA7073MPRT carry ROHS3 compliance certification and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory alignment for current manufacturing standards.

Q: What is the significance of the SLA7073MPRT being in active product status?

A: Active product status indicates ongoing manufacturer support, production availability, and supply chain continuity. This contrasts with the obsolete status of the SLA7073MS, making the SLA7073MPRT the recommended choice for new designs and component replenishment.
