1. XC6210A202PR-G Substitution Conclusion
Based on the technical parameter comparison, the XC6210A202PR-G exhibits high consistency with the original model XC6210B202PR-G in terms of fundamental electrical characteristics. These include output voltage (2V), maximum input voltage (6V), output current (700mA), dropout voltage (0.12V @ 100mA), PSRR (60dB), package (SOT-89-5/6), as well as control and protection functions.
The primary deviation lies in the quiescent current (Iq), which has increased from the original 55 µA to 64.5 µA. Under no-load or light-load conditions, the XC6210A202PR-G will draw higher standby power, potentially causing a slight impact on system efficiency in battery-powered or low-power applications—such as reduced battery life or increased thermal dissipation.
If the target application is not sensitive to power consumption or can tolerate a minor efficiency trade-off, and all other parameters are fully matched, then the XC6210A202PR-G can serve as a viable substitute. However, if the application critically depends on low quiescent current to extend runtime, careful evaluation is recommended, or the original model should be prioritized.
2. XC6210C202PR-G Substitution Conclusion
The XC6210C202PR-G is nearly identical to the original model XC6210B202PR-G in key parameters such as output voltage, current capability, dropout voltage, PSRR, package, and functional characteristics, ensuring basic performance compatibility.
Similarly, the difference is observed in the quiescent current (Iq), which has increased from the original 55 µA to 64.5 µA. This change means the XC6210C202PR-G will exhibit higher internal power dissipation under no-load conditions, potentially leading to a slight reduction in overall system energy efficiency. In continuously standby scenarios, this may result in marginally higher power consumption and a slight increase in thermal risk.
Given the consistency in other specifications, if the application does not demand extremely low quiescent current—for example, in non-battery-operated designs or those with relaxed power budgets—the XC6210C202PR-G can be used as a direct replacement. For power-sensitive designs, however, it is advisable to verify the impact of the increased quiescent current on the overall system, or to consider retaining the original model to optimize energy efficiency.
