Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC9221D095ER-G are identified based on strict parametric equivalence within the allowed electrical and mechanical specifications for buck regulator controller ICs. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 2.8V ~ 16V (identical across all parts)
• Output configuration: Positive, single output
• Topology: Buck regulator
• Duty cycle maximum: 100%
• Control features: Enable, Soft Start
• Operating temperature range: -40°C ~ 85°C

Mechanical Compatibility Criteria:

• Package type: 6-UFDFN Exposed Pad
• Supplier device package: 6-USPC (1.8x2)
• Mounting type: Surface Mount

Regulatory & Compliance Criteria:

• RoHS3 Compliant
• MSL Level 1 (Unlimited)
• REACH Unaffected
• ECCN: EAR99

The primary differentiator among substitute parts is the switching frequency specification. The XC9221D095ER-G operates at 500kHz, while substitute models operate at 1MHz. This parameter variation allows selection based on application-specific requirements for efficiency, noise, and component sizing.

Parameter Comparison

Engineering Selection Recommendations

XC9221D095ER-G (Primary Part): Active product status with established supply. Operates at 500kHz switching frequency. Select this part when the application design specifies 500kHz operation or when existing inventory meets project timelines.

XC9220C09AER-G (Substitute - Series XC9220): Active product status with higher inventory availability (1202 units). Operates at 1MHz switching frequency. This part belongs to the XC9220 series and provides equivalent electrical and mechanical functionality with increased switching frequency. Select when higher switching frequency is compatible with application requirements or when inventory priority is critical.

XC9221A09AER-G (Substitute - Series XC9221): Active product status with high inventory availability (1200 units). Operates at 1MHz switching frequency. This part remains within the XC9221 series while providing 1MHz operation. Select when series continuity is preferred and 1MHz switching frequency is acceptable for the application.

All three parts maintain identical compliance certifications (ROHS3, MSL Level 1, REACH Unaffected) and identical mechanical packaging (6-USPC 1.8x2). All parts are suitable for surface mount assembly in the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between XC9221D095ER-G and its substitutes?

A: The primary difference is switching frequency. The XC9221D095ER-G operates at 500kHz, while XC9220C09AER-G and XC9221A09AER-G operate at 1MHz. All other electrical parameters, mechanical packaging, and compliance certifications are identical.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the 6-UFDFN Exposed Pad package with 6-USPC (1.8x2) supplier device package specification. The physical footprint and pin configuration are identical, enabling direct PCB substitution.

Q: Can I substitute XC9221D095ER-G with XC9220C09AER-G?

A: Yes, provided the application design accommodates 1MHz switching frequency instead of 500kHz. The electrical input/output specifications, voltage range, duty cycle, and control features are fully equivalent. Verify that higher switching frequency does not negatively impact filter component sizing, EMI characteristics, or thermal performance in your specific application.

Q: What is the difference between XC9220C09AER-G and XC9221A09AER-G?

A: Both parts operate at 1MHz and share identical electrical and mechanical specifications. The primary difference is series designation (XC9220 vs. XC9221). Both are suitable substitutes for the XC9221D095ER-G. Selection between these two can be based on inventory availability or design documentation preferences.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant certification and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the MSL rating for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your application design and testing confirm compatibility with the switching frequency of the selected substitute. The 6-USPC (1.8x2) package ensures mechanical and electrical interchangeability. Update component documentation and bill of materials accordingly.
