1. XC6221A092GR-G Substitution Conclusion
This device is a viable substitute, but attention must be paid to the difference in power consumption. The key distinction between the XC6221A092GR-G and the original model XC6217D092GR-G is the increase in quiescent current (Iq) from 8µA to 50µA. Additionally, the "Supply Current (Max)" parameter specified for the original model is not explicitly defined in the substitute's datasheet. All other core parameters—such as input/output voltage, output current, dropout voltage, PSRR, enable control, and package—are fully identical. Electrically, the two devices are largely compatible. However, the substitute will exhibit significantly higher power consumption under light-load or standby conditions, which may impact the battery life of power-sensitive applications (e.g., battery-powered devices). If the application is not critical regarding quiescent current, direct substitution is acceptable.
2. XC6221B092GR-G Substitution Conclusion
The conclusion is identical to that for the XC6221A092GR-G; please refer to the analysis above. According to the provided parameter tables, the XC6221B092GR-G and the XC6221A092GR-G share completely identical specifications, including the 50µA quiescent current. They are likely different versions within the same series, possibly with minor variations in production batches or internal testing standards. Therefore, their feasibility and considerations for substituting the original model are the same as for the A version, with the increased quiescent current and its impact on power consumption being the primary points of concern.
