2. BBUP00160805101Y00 Substitution Conclusion Substitution is acceptable, with certain performance advantages. This part matches the original in critical filtering characteristics (100Ω at 100MHz) and current handling capability (3A). Two notable differences exist: first, its maximum DC resistance is lower (25mΩ vs. 30mΩ), which reduces DC voltage drop and power loss under the same operating current, thereby improving power efficiency. Second, its profile is lower (0.65mm vs. 0.95mm), offering an advantage in height-constrained applications such as ultra-thin devices. However, note that the reduced magnetic core volume may affect high-frequency impedance characteristics or saturation current behavior. It is advisable to review the detailed impedance-frequency curve to ensure performance meets requirements across the target frequency range.
