1. MH1608-101Y Substitution Conclusion
The MH1608-101Y can directly replace the original MH1608-101T. Both parts share identical key electrical parameters: 100Ω impedance @ 100MHz, a 3A rated current, and a maximum DC resistance of 40mΩ. Consequently, their filtering performance, current-handling capability, and power dissipation in-circuit will be exactly the same. The primary differences are limited to the part number suffix (changing from "T" to "Y") and a minor discrepancy in the documented width (0.032” vs. 0.031”). These variations typically indicate differences in manufacturing lot, packaging, or documentation revision and do not affect the actual physical dimensions or solder compatibility. Therefore, the substitution is feasible and functionally equivalent.
2. MH1608-800Y Substitution Conclusion
The MH1608-800Y is not a direct, equivalent replacement for the MH1608-101T, and substitution requires evaluation based on the specific application. The critical difference lies in the impedance value: the MH1608-800Y has an impedance of 80Ω @ 100MHz, which is 20% lower than the original part's 100Ω. At the same 100MHz noise frequency, this results in weaker attenuation (i.e., reduced noise suppression capability). While the rated current, DC resistance, and package dimensions are identical, the impedance difference directly impacts the core performance of the filter. Direct replacement could lead to insufficient high-frequency noise suppression compared to the original design intent. Thus, substitution should only be considered in applications where impedance tolerance is acceptable or where the attenuation requirement at 100MHz is not critical.
