Substitute Part Grouping Explanation

Substitute parts for the XC6222B331ER-G are identified 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:

• Output Voltage (Fixed): 3.3V
• Output Current: 700mA
• Input Voltage (Max): 6V
• Voltage Dropout (Max): 0.2V @ 300mA
• Quiescent Current (Iq): 220 µA
• PSRR: 65dB (1kHz)
• Package / Case: 6-UFDFN Exposed Pad
• Supplier Device Package: 6-USPC (1.8x2)
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Control Features: Enable
• Protection Features: Over Current, Over Temperature, Reverse Polarity
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The XC6222B331ER-G belongs to the XC6222 base product family, and substitutes within this family maintain full electrical and mechanical compatibility.
