Substitute Part Grouping Explanation

Substitute parts for the SLA7072MR are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Primary Matching Criteria:

• Motor type: Unipolar stepper
• Function: Fully integrated driver with control and power stage
• Output configuration: Low side (4)
• Interface: Parallel
• Technology: Power MOSFET
• Step resolution: 1, 1/2
• Supply voltage range: 3V ~ 5.5V
• Load voltage range: 10V ~ 44V
• Operating temperature range: -20°C ~ 150°C (TJ)
• Package: 23-ESIP Formed Leads (23-ZIP)
• Mounting type: Through Hole
• RoHS compliance: Yes
• MSL rating: 1 (Unlimited)

Secondary Consideration:

• Output current rating may vary within application tolerance

The SLA7072MPRT and SLA7071MPRT meet these criteria and are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

SLA7072MPRT is the primary substitute for the obsolete SLA7072MR. Both parts share identical electrical specifications, including 2A output current, and are manufactured by the same supplier. The SLA7072MPRT carries active product status, ensuring ongoing availability and supply chain support. All compliance certifications, including RoHS compliance and MSL rating, are equivalent.

SLA7071MPRT is a parametric equivalent with a reduced output current rating of 1.5A compared to the 2A specification of the SLA7072MR. This part is suitable for applications where the lower current rating meets design requirements. The SLA7071MPRT is also active and fully compliant with all regulatory standards.

Selection between SLA7072MPRT and SLA7071MPRT depends on application current requirements. For designs requiring 2A output capability, SLA7072MPRT is the appropriate choice. For applications with lower current demands, SLA7071MPRT provides a viable alternative.

Frequently Asked Questions (FAQ)

Q: Can SLA7072MPRT be used as a direct replacement for SLA7072MR?

A: Yes. The SLA7072MPRT is electrically and mechanically identical to the SLA7072MR across all specified parameters. Both parts feature 2A output current, identical supply and load voltage ranges, and the same 23-ESIP package. The primary difference is product status: SLA7072MPRT is active, while SLA7072MR is obsolete.

Q: What is the difference between SLA7072MPRT and SLA7071MPRT?

A: The primary difference is output current rating. SLA7072MPRT provides 2A output current, while SLA7071MPRT provides 1.5A. All other electrical and mechanical parameters are identical. Selection depends on application current requirements.

Q: Are there packaging differences between these parts?

A: SLA7072MR and SLA7072MPRT have no specified packaging designation. SLA7071MPRT is supplied in Tube packaging. All three parts use the same 23-ESIP Formed Leads package case and are through-hole mounted components.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. SLA7072MR, SLA7072MPRT, and SLA7071MPRT are all RoHS compliant with MSL rating of 1 (Unlimited).

Q: Can SLA7071MPRT replace SLA7072MR in all applications?

A: SLA7071MPRT can replace SLA7072MR only in applications where the reduced 1.5A output current rating is acceptable. Applications requiring the full 2A output capability must use SLA7072MPRT.
