1. XC6501C2717R-G Substitution Conclusion
This device can be substituted, but performance differences must be considered. Compared to the original part, the key variations are: a higher dropout voltage (0.38V @ 200mA vs. original 0.17V @ 100mA), requiring a larger input‑output differential for stable operation, making it unsuitable for low‑power applications with limited input voltage headroom; a lower quiescent current (20µA vs. 50µA), which benefits standby power in battery‑powered systems; and a significantly reduced PSRR (50dB vs. 70dB), resulting in weaker power‑supply noise rejection that may affect stability in noise‑sensitive circuits. If the application is not critical to dropout voltage and noise suppression, and prioritizes low quiescent current, substitution is acceptable.
2. XC6501D2717R-G Substitution Conclusion
Identical to the XC6501C2717R-G; the substitution conclusion is the same. This part shares identical parameters with the C version (dropout 0.38V @ 200mA, quiescent current 20µA, PSRR 50dB), exhibiting the same increased dropout and reduced noise rejection, while offering the same quiescent‑current advantage. The only differences likely relate to internal production lots or test standards; electrical characteristics are equivalent. If the application tolerates higher dropout and lower PSRR, and low quiescent current is a priority, this device can directly replace the original part.
