Original Part
100 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 2A 55mOhm
Alternative Part
120 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 2A 50mOhm
100 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 3A 30mOhm
1. PZ1608U121-2R0TF Substitution Conclusion
This part can serve as a direct replacement for the original component. However, note that its impedance increases from 100Ω to 120Ω (@100MHz), which slightly enhances high-frequency noise suppression. Meanwhile, the DC resistance (DCR) drops from 55mΩ to 50mΩ, helping to reduce DC losses. If the original design is sensitive to impedance tolerance around 100MHz, verification of the filtering performance may be required to ensure it still meets specifications. If there are no strict impedance matching requirements and the current rating (2A) remains compatible, the part can be substituted directly.
2. UPZ1608E101-3R0TF Substitution Conclusion
This part represents a superior alternative. It maintains the same impedance (100Ω @100MHz) while increasing the rated current from 2A to 3A and significantly reducing the DC resistance (DCR) from 55mΩ to 30mΩ, offering higher power handling capability and lower conduction loss. Although the body length increases slightly by 0.05mm (1.65mm vs. 1.60mm), it remains compatible with the 0603 footprint and generally does not affect solderability. If the layout can accommodate this minor length difference, this part is recommended to enhance system reliability.
