1. XC6210B402PR-G Substitution Conclusion
Feasible, direct replacement is acceptable. The key technical difference between the XC6210B402PR-G and the original part XC6210C402PR-G is the reduction in quiescent current (Iq) from 70.5 µA to 55 µA. All other core parameters—including output voltage (4V), maximum output current (700mA), dropout voltage (0.075V @100mA), PSRR (60dB), enable control, and overcurrent protection—remain identical. The lower quiescent current results in improved power efficiency under light-load or standby conditions, which is beneficial for extending battery life in portable devices. No adverse effects are introduced, making this part a suitable drop-in replacement for the original.
2. XC6210D402PR-G Substitution Conclusion
Feasible, direct replacement is acceptable. Similarly, the XC6210D402PR-G differs from the original XC6210C402PR-G only in its reduced quiescent current (Iq), lowered from 70.5 µA to 55 µA. All other electrical specifications, package (SOT-89-5), and functional characteristics are fully consistent. The lower Iq contributes to reduced standby power consumption, making it suitable for power-sensitive applications. Critical performance metrics such as output accuracy and load capability remain unaffected. Therefore, this part is also a viable direct replacement for the original.
