Substitute Part Grouping Explanation

Substitute parts for the SLA7070MPR are identified based on strict parameter compatibility within the unipolar stepper motor driver category. The following criteria determine substitution eligibility:

Core Compatibility Parameters:

  • Motor Type: Unipolar Stepper
  • Function: Driver - Fully Integrated, Control and Power Stage
  • Output Configuration: Low Side (4)
  • Interface: Parallel
  • Technology: Power MOSFET
  • Voltage - Supply: 3V ~ 5.5V
  • Voltage - Load: 10V ~ 44V
  • Operating Temperature: -20°C ~ 150°C (TJ)
  • Mounting Type: Through Hole
  • Package / Case: 23-ESIP Formed Leads

Substitutes are grouped into two categories:

  1. MFR Recommended Substitute (SLA7077MPRT): Maintains all core compatibility parameters while offering enhanced specifications in current output (2A vs. 1A) and step resolution (1, 1/2, 1/4, 1/8, 1/16 vs. 1, 1/2). Product status is Active with higher inventory availability.

  2. Parametric Equivalent (SLA7070MPRT): Maintains identical electrical and mechanical specifications to the main part, including 1A output current and 1, 1/2 step resolution. Product status is Active with comparable inventory levels.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Specification-Identical): The SLA7070MPRT serves as the direct parametric equivalent to the SLA7070MPR. Both devices share identical electrical specifications, including 1A output current and 1, 1/2 step resolution. The SLA7070MPRT maintains RoHS Compliant status and is currently in Active product status with substantial inventory availability (40,200 pcs). This part is suitable for applications requiring exact specification matching.

For Enhanced Performance Applications: The SLA7077MPRT is the manufacturer-recommended substitute, offering increased output current capability (2A vs. 1A) and extended step resolution options (1, 1/2, 1/4, 1/8, 1/16). This device is ROHS3 Compliant and maintains Active product status with higher inventory levels (40,400 pcs). The SLA7077MPRT is appropriate for designs that can accommodate higher current output or require finer step resolution control.

Compliance Considerations: Both substitute parts maintain the same operating temperature range (-20°C ~ 150°C TJ), supply voltage range (3V ~ 5.5V), and load voltage range (10V ~ 44V) as the original part. The SLA7077MPRT provides enhanced RoHS3 compliance compared to the RoHS Compliant status of the main part and SLA7070MPRT.

Frequently Asked Questions (FAQ)

Q: Can the SLA7077MPRT be used as a direct replacement for the SLA7070MPR? A: The SLA7077MPRT is electrically and mechanically compatible with the SLA7070MPR across all core parameters. However, the SLA7077MPRT provides enhanced specifications: 2A output current versus 1A, and extended step resolution (1, 1/2, 1/4, 1/8, 1/16 versus 1, 1/2). Applications designed for 1A operation will function correctly with the SLA7077MPRT, as it is backward-compatible in this regard.

Q: What is the difference between the SLA7070MPRT and SLA7077MPRT? A: The SLA7070MPRT maintains identical specifications to the original SLA7070MPR, including 1A output current and 1, 1/2 step resolution. The SLA7077MPRT offers enhanced capabilities with 2A output current and additional step resolution options (1/4, 1/8, 1/16). Both devices share the same 23-ESIP package and through-hole mounting configuration.

Q: Are all three parts available in the same packaging? A: All three parts use the 23-ESIP Formed Leads package with through-hole mounting. The SLA7077MPRT is supplied in Tube packaging, while the SLA7070MPR and SLA7070MPRT packaging specifications are not specified in the available data.

Q: What is the significance of the product status difference? A: The SLA7070MPR is classified as Obsolete, indicating it is no longer manufactured. The SLA7070MPRT and SLA7077MPRT are both Active products with current manufacturing and substantial inventory availability, ensuring long-term supply chain reliability.

Q: Do these parts meet current RoHS requirements? A: The SLA7070MPR and SLA7070MPRT are RoHS Compliant. The SLA7077MPRT meets the more recent ROHS3 Compliant standard. All three parts maintain Moisture Sensitivity Level 1 (Unlimited).
