1. AX3DBF1-125.0000T Substitution Conclusion From the perspective of core electrical parameters and mechanical package, this model can be considered a direct replacement. However, key performance differences require careful evaluation. The primary difference is its slightly higher operating current (27mA vs. 23mA), which increases system power consumption and heat generation. A more critical distinction is its extremely low disable-state current (10µA vs. 18mA). When utilizing the Enable/Disable function, the Abracon model offers a significant advantage in static power consumption, which is highly beneficial for battery-powered or low-power designs. However, if the original circuit design relies on the higher current present in the disabled state of the Skyworks model (e.g., to provide hold current for certain loads), direct substitution may lead to functional anomalies.
