XC9302A592MR-G Equivalent & Substitute Parts

Part Overview

The XC9302A592MR-G is a buck-boost regulator positive output step-up/step-down DC-DC controller IC manufactured by Torex Semiconductor Ltd. This PWM-based power management IC operates at 180kHz switching frequency and supports input voltage ranges from 2V to 10V with a maximum duty cycle of 92%. The device is housed in an SC-74A SOT-753 package (SOT-25-5 supplier designation) and is designed for surface mount applications requiring single-output buck-boost topology with enable control features.

The XC9302A592MR-G maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are necessary when primary part availability is limited, when inventory requirements exceed current stock levels, or when design flexibility permits selection from the XC9302 and XC9301 series variants that share identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC9302A592MR-G are selected based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Specifications:

• Input voltage supply range: 2V ~ 10V
• Switching frequency: 180kHz
• Maximum duty cycle: 92%
• Output type: PWM
• Topology: Buck-Boost
• Output configuration: Positive
• Number of outputs: 1

Mechanical & Environmental Specifications:

• Package type: SC-74A, SOT-753 (SOT-25-5 supplier designation)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C
• Control features: Enable

Compliance & Regulatory:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed maintain identical specifications across these parameters. Differences exist only in the base product number designation (XC9302 versus XC9301 series) and specific part number suffixes, which do not affect functional equivalence or circuit-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—XC9302A592MR-G, XC9302A552MR-G, and XC9301A332MR-G—are functionally equivalent and directly substitutable based on electrical and mechanical parameters. Selection among these parts should be based on the following engineering criteria:

Availability & Inventory:

• XC9301A332MR-G: 1079 Pcs in stock
• XC9302A552MR-G: 977 Pcs in stock
• XC9302A592MR-G: 992 Pcs in stock

All parts maintain active product status with no end-of-life indicators. Each part carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for power management applications.

Compliance Considerations: All substitute parts share identical RoHS3 compliance, REACH status, and moisture sensitivity ratings. No additional qualification or testing is required when substituting between these parts in existing designs. The ECCN classification (EAR99) and HTSUS code (8542.39.0001) remain consistent across all variants.

Circuit-Level Compatibility: Direct substitution is supported at the circuit board level without modification to PCB layout, component values, or control signal routing. The identical SOT-25-5 package footprint, pin configuration, and electrical specifications ensure drop-in compatibility.

Frequently Asked Questions (FAQ)

Q: Can XC9302A552MR-G be used as a direct replacement for XC9302A592MR-G?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (2V-10V input, 180kHz switching frequency, 92% maximum duty cycle, PWM output type) and mechanical specifications (SOT-25-5 package, surface mount, -40°C to 85°C operating range). Direct substitution is supported without circuit modification.

Q: What is the difference between the XC9302 and XC9301 series?

A: The XC9302A592MR-G and XC9301A332MR-G differ only in base product number designation. All electrical parameters, switching frequency, duty cycle, input voltage range, and output configuration are identical. Both are buck-boost regulators with positive output configuration and PWM control. The series designation does not affect functional equivalence or circuit compatibility.

Q: Are all three parts suitable for the same PCB footprint?

A: Yes. All three parts use the SC-74A SOT-753 package (SOT-25-5 supplier designation), which provides identical pin configuration and footprint dimensions. No PCB layout changes are required when substituting between these parts.

Q: Do these parts require different control signal levels or enable pin configurations?

A: No. All three parts include identical enable control features and operate with the same control signal specifications. Enable pin functionality and control logic are equivalent across all substitute parts.

Q: What is the moisture sensitivity rating for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under standard storage conditions. No special moisture control measures are required during handling, storage, or assembly.

Q: Are there any temperature range differences between substitute parts?

A: No. All three parts operate across the identical temperature range of -40°C to 85°C. Thermal performance and operating envelope are equivalent.

Q: Can these parts be used interchangeably in production without design review?

A: Yes, provided the original design was qualified for one of these three parts. Since all electrical, mechanical, and compliance specifications are identical, substitution does not require design re-qualification or additional testing.

Q: What compliance certifications apply to all substitute parts?

A: All three parts carry ROHS3 compliance certification and REACH unaffected status. ECCN classification is EAR99 for all variants. Regulatory compliance is maintained across all substitute selections.
