Original Part
80 Ohms @ 100 MHz 1 Power, Signal Line Ferrite Bead 0603 (1608 Metric) 300mA 300mOhm

Alternative Part
80 Ohms @ 100 MHz 1 Ferrite Bead 0603 (1608 Metric) 600mA 100mOhm

70 Ohms @ 100 MHz 1 Signal Line Ferrite Bead 0603 (1608 Metric) 600mA 100mOhm

1. WLBD1608K2U800TP Substitution Conclusion
This part is a highly feasible direct replacement option with enhanced performance. The key differences are its increased rated current to 600mA (compared to 300mA for the original) and reduced DC resistance (DCR) to 100mΩ (versus 300mΩ). Under identical operating currents, the WLBD1608K2U800TP exhibits lower heat generation and reduced power dissipation, offering greater design margin and improved reliability. Although its datasheet does not explicitly label it as a "Power Line" filter type, general-purpose ferrite beads in a 0603 package are commonly used for both signal and power supply decoupling, presenting minimal risk in practical applications. Other critical parameters, such as impedance (80Ω @ 100MHz) and package size (0603), are fully compatible, confirming high substitution feasibility.
2. BBGK00160808700Y00 Substitution Conclusion
This part can serve as a conditional substitute, requiring evaluation based on specific circuit filtering requirements. The core difference is its nominal impedance of 70Ω @ 100MHz (compared to 80Ω for the original). Around the target frequency (100MHz), its noise attenuation characteristics will be slightly weaker than the original, which may impact high-frequency filtering performance. On the other hand, similar to the WLBD1608K2U800TP, it features a higher rated current (600mA) and lower DC resistance (100mΩ), offering advantages in electrical and thermal performance. If the circuit is not sensitive to the precise 100MHz impedance value or allows for some tolerance in filtering characteristics, this part can be substituted. Otherwise, it is not recommended.
