SLA7076MR Equivalent & Substitute Parts

Part Overview

The SLA7076MR is a unipolar stepper motor driver IC manufactured by Sanken Electric USA Inc., designed for general-purpose motor control applications. It 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 up to 44V. The device is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the SLA7076MR is determined by strict equivalence across the following critical parameters:

• Motor Type & Function: Unipolar stepper motor driver with fully integrated control and power stage
• Output Configuration & Interface: Low-side 4-channel output with parallel interface
• Electrical Specifications: 3V–5.5V supply voltage, 1.5A output current, 10V–44V load voltage range
• Step Resolution Capability: Support for 1, 1/2, 1/4, 1/8, and 1/16 step modes
• Package & Mounting: 23-ESIP formed leads, through-hole mounting
• Environmental & Compliance: Operating temperature range -20°C to 150°C, RoHS compliance, MSL Level 1

The SLA7076MPRT is identified as the manufacturer-recommended substitute, maintaining identical electrical and mechanical specifications while differing only in product status (active vs. obsolete) and packaging format (tube vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The SLA7076MPRT is the direct equivalent substitute for the SLA7076MR. Both devices share identical electrical performance, mechanical form factor, and environmental specifications. The primary distinction is product lifecycle status: the SLA7076MR is obsolete, while the SLA7076MPRT remains in active production.

Selection of the SLA7076MPRT is supported by:

• Identical electrical and functional specifications across all critical parameters
• Maintained RoHS compliance and MSL Level 1 rating
• Continued manufacturer support and active inventory availability
• No design modifications required for PCB integration or circuit operation

The tube packaging format of the SLA7076MPRT is compatible with standard component handling and assembly processes used for through-hole mounted devices.

Frequently Asked Questions (FAQ)

Q: Can the SLA7076MPRT be used as a direct replacement for the SLA7076MR without circuit modifications?

A: Yes. The SLA7076MPRT is electrically and mechanically identical to the SLA7076MR. No circuit design changes are required. Both devices operate identically across all specified voltage, current, temperature, and functional parameters.

Q: What is the difference between the SLA7076MR and SLA7076MPRT?

A: The devices are functionally equivalent. The SLA7076MR is classified as obsolete, while the SLA7076MPRT is in active production. The packaging format differs (standard vs. tube), but both use the same 23-ESIP formed leads package for through-hole mounting.

Q: Are there any compatibility concerns with the tube packaging of the SLA7076MPRT?

A: No. Tube packaging is a standard format for through-hole components and is compatible with conventional component handling, pick-and-place equipment, and manual assembly processes. The device pinout and electrical interface remain unchanged.

Q: Does the SLA7076MPRT maintain the same RoHS and MSL certifications?

A: Yes. The SLA7076MPRT is RoHS compliant and carries MSL Level 1 (Unlimited) rating, identical to the SLA7076MR.

Q: What step resolutions are supported by the SLA7076MPRT?

A: The SLA7076MPRT supports full-step (1), half-step (1/2), quarter-step (1/4), eighth-step (1/8), and sixteenth-step (1/16) resolutions, matching the SLA7076MR specification.
