Parameter Comparison

Engineering Selection Recommendations

All three parts—XC9301A592MR-G, XC9301A332MR-G, and XC9302A552MR-G—maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined by availability and inventory levels rather than electrical or mechanical differentiation.

XC9301A332MR-G offers the highest current inventory at 1079 pieces, making it the preferred choice for immediate procurement when the primary part number is unavailable.

XC9302A552MR-G provides an alternative within the XC9302 series with 977 pieces in stock, suitable for applications where series-level compatibility is acceptable.

All substitute parts are certified for the same operating temperature range (-40°C to 85°C), moisture sensitivity classification (MSL 1), and regulatory compliance frameworks. Direct PCB-level substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can XC9301A332MR-G be used as a direct replacement for XC9301A592MR-G?

A: Yes. Both parts share identical electrical specifications (Buck-Boost topology, 180kHz switching frequency, 2V-10V supply voltage, 92% maximum duty cycle), mechanical packaging (SOT-25-5, SC-74A case), and environmental ratings (-40°C to 85°C operating temperature, MSL 1). Direct PCB substitution is supported without circuit modification.

Q: What is the difference between XC9301A332MR-G and XC9302A552MR-G?

A: Both parts are functionally equivalent with identical electrical and mechanical parameters. The primary difference is series designation: XC9301A332MR-G belongs to the XC9301 series, while XC9302A552MR-G belongs to the XC9302 series. All critical specifications—topology, switching frequency, supply voltage range, duty cycle, package type, and operating temperature—are identical.

Q: Are all three parts RoHS3 compliant?

A: Yes. XC9301A592MR-G, XC9301A332MR-G, and XC9302A552MR-G are all ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Can these parts be used in applications requiring -40°C to 85°C operation?

A: Yes. All three substitute parts are rated for -40°C to 85°C operating temperature range, supporting industrial and extended-temperature applications without thermal derating.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that these components have no moisture sensitivity limitations. They can be stored indefinitely without desiccant packaging and do not require special moisture control during assembly, simplifying logistics and manufacturing processes.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use identical packaging: SC-74A case with SOT-753 designation and SOT-25-5 supplier device package. Pinout and PCB footprint compatibility is guaranteed across all substitute parts.
