Original Part
30 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 3A 30mOhm
Alternative Part
30 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 5A 10mOhm
26 Ohms @ 100 MHz 1 Power Line Ferrite Bead 0603 (1608 Metric) 6A 7mOhm
1. UPZ1608E300-5R0TF Substitution Conclusion
Fully compatible with superior performance. This part is identical to the original part in core filtering characteristics (impedance @ frequency: 30Ω @ 100MHz) and package dimensions, ensuring equivalent high‑frequency noise suppression and mounting compatibility. The key improvements are its increased rated current from 3A to 5A and reduced DCR from 30mΩ to 10mΩ. Under the same operating current, power dissipation and temperature rise of the bead will be significantly lower, providing greater current headroom and lower DC voltage drop on the power line. It is an ideal drop‑in upgrade.
2. WLBD1608HCU260TL Substitution Conclusion
Substitution is feasible under specific conditions, but the impact of key parameter differences must be evaluated. The package is compatible, and this part offers higher rated current (6A) and lower DCR (7mΩ), providing better electrical margin. The main deviation is its nominal impedance of 26Ω @ 100MHz, which is slightly lower than the original 30Ω. Consequently, noise suppression around the target frequency (100MHz) will be somewhat reduced. If the original design has strict attenuation margin requirements at this frequency, further validation is advised. For general power‑line filtering where higher current capability is prioritized, this part is a viable alternative, though its reduced profile may require attention to soldering process compatibility.
