Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLA7072MPR are identified based on strict electrical and mechanical parameter matching within the unipolar stepper motor driver category. The critical parameters determining substitution eligibility are:

• Motor Type: Unipolar stepper configuration
• Function: Fully integrated driver with control and power stage
• Output Configuration: Low side (4-channel)
• Interface: Parallel control
• Technology: Power MOSFET
• Supply Voltage Range: 3V ~ 5.5V
• Load Voltage Range: 10V ~ 44V
• Operating Temperature Range: -20°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package: 23-ESIP Formed Leads
• RoHS Compliance: Required

The SLA7072MPRT qualifies as a direct substitute with identical electrical specifications and active product status. The SLA7071MPRT is a parametric equivalent with a reduced output current rating of 1.5A (versus 2A), making it suitable only for applications with lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

The SLA7072MPRT is the primary substitute for the obsolete SLA7072MPR. Both parts maintain identical electrical and mechanical specifications, with the SLA7072MPRT offering active product status and significantly higher inventory availability (40,300 units versus 2,220 units). Both parts carry RoHS compliance certification and MSL Level 1 rating, meeting environmental and reliability requirements.

The SLA7071MPRT serves as a parametric equivalent for applications where the reduced output current specification of 1.5A is acceptable. This part is also active and RoHS compliant. Selection of the SLA7071MPRT requires confirmation that motor load current does not exceed 1.5A per channel.

All three parts share identical package geometry (23-ESIP Formed Leads), supply voltage range (3V ~ 5.5V), load voltage range (10V ~ 44V), and operating temperature range (-20°C ~ 150°C TJ), ensuring mechanical and thermal compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SLA7072MPRT directly replace the SLA7072MPR without circuit modification?

A: Yes. The SLA7072MPRT is electrically and mechanically identical to the SLA7072MPR. No circuit modifications are required for substitution.

Q: What is the key difference between the SLA7072MPRT and SLA7071MPRT?

A: The primary difference is output current rating. The SLA7072MPRT provides 2A per channel, while the SLA7071MPRT provides 1.5A per channel. All other electrical and mechanical parameters are identical.

Q: Can the SLA7071MPRT be used in place of the SLA7072MPR?

A: The SLA7071MPRT is suitable only if the application motor current requirement does not exceed 1.5A per channel. If the design requires 2A output capability, the SLA7072MPRT is the appropriate substitute.

Q: Are all three parts RoHS compliant?

A: Yes. The SLA7072MPR, SLA7072MPRT, and SLA7071MPRT are all RoHS compliant with MSL Level 1 rating.

Q: What is the package type for these parts?

A: All three parts use the 23-ESIP Formed Leads package with through-hole mounting. The package designation is 23-ZIP (SLA).

Q: Which substitute part has the best inventory availability?

A: The SLA7072MPRT has the highest inventory availability at 40,300 units in stock, compared to 4,379 units for the SLA7071MPRT.
