1. Substitution Conclusion for 514FBB000115CAGR
Direct substitution is feasible in terms of electrical interface and core functionality, provided the power consumption requirements are critically evaluated. The key parameters (frequency, voltage, output type, package, frequency stability) of both devices are identical. The primary deviation lies in the current consumption: the original device has a maximum operating current of 27mA and a disabled-state current of only 10µA, whereas the 514FBB000115CAGR exhibits a slightly better operating current of 23mA but a significantly worse disabled-state current of 18mA. This represents a difference of nearly 1800x in disabled-state current.
If the system relies on the "disable" state for low-power standby or power management, the substitute will cause a substantial increase in standby power consumption. This likely renders it unsuitable for battery-powered designs or applications sensitive to static power draw. However, if the disable function is used solely for enable/control purposes and power consumption is not a critical factor, direct replacement is acceptable.
2. Substitution Conclusion for 510FBA125M000CAGR
The situation is identical to that of the 514FBB000115CAGR, requiring the same vigilance regarding high disabled-state power consumption. This device's parameters are completely aligned with the 514FBB000115CAGR (including 23mA operating current and 18mA disabled-state current). The points of divergence from the original part are also exactly the same.
Its disabled current of 18mA remains vastly higher than the original part's 10µA. This suggests both substitute devices likely share the same internal Skyworks architecture, which features a fundamentally different circuit design in the disabled mode (e.g., the output stage or bias circuitry remains active) compared to the original Abracon part.
Substitutability hinges entirely on whether the application requires an extremely low disabled-state current. If the system does not require low-power standby, replacement is viable. If low standby power is a requirement, the substitution is unacceptable.
