Substitute Part Grouping Explanation

Substitute parts for the XC6220A321PR-G are identified through parametric equivalence. The substitution logic is based on the following critical parameters that must remain identical:

• Fixed output voltage of 3.2V
• Maximum output current of 1A
• Maximum input voltage of 6V
• Dropout voltage specification of 0.655V @ 1A
• Quiescent current of 18 µA
• PSRR of 50dB (1kHz)
• Operating temperature range of -40°C ~ 85°C
• SOT-89-5 package configuration
• Enable control feature
• Over-current and over-temperature protection
• Surface-mount mounting type
• RoHS3 compliance and MSL Level 1 rating

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
