1. 514FBB000115CAGR Substitution Conclusion
From the perspective of core electrical parameters, package, and functionality, the 514FBB000115CAGR can serve as a direct replacement for the original part number, as its frequency, output type, voltage, stability, and package dimensions are fully matched. However, one critical discrepancy exists: the supply current in the disabled state. The original part has a maximum disabled current of only 10µA, whereas the 514FBB000115CAGR draws up to 18mA. If your system design relies on the enable/disable function to achieve ultra-low power consumption during standby, this substitute will cause the quiescent power dissipation to surge by nearly 1800 times. This could severely impact the overall system power budget, potentially leading to excessive heat or failure to meet battery life targets. If the disable function is used solely for signal switching control and not for power saving, then the substitution is entirely viable.
2. 510FBA125M000CAGR Substitution Conclusion
The substitution feasibility for the 510FBA125M000CAGR is identical to that of the 514FBB000115CAGR. It is compatible with the original part in all active operating parameters (frequency, output, voltage, stability, operating current) and in package footprint, making it a direct functional and form-factor replacement. Similarly, its disabled-state current of 18mA presents a substantial deviation from the original part's 10µA. This difference directly dictates the applicable scenarios for the substitution: it is a qualified replacement in applications where the device is always powered or where disable-state power is not a concern. However, in critical designs that depend on the disable pin to achieve ultra-low standby power—such as in battery-powered portable devices—this discrepancy would render the system incapable of meeting low-power requirements, making the substitution unacceptable.
