1. FMAT7466-1 Substitution Conclusion In terms of core specifications such as attenuation value, power handling capability, and interface matching, the FMAT7466-1 is fully equivalent to the original part number. Therefore, for systems operating at or below 12 GHz, it can serve as a direct, drop-in replacement with no significant performance deviation. The primary technical distinction lies in its frequency range (0–12 GHz), which is narrower than the original part's DC–18 GHz range. When the operating frequency exceeds 12 GHz, parameters such as attenuation accuracy and VSWR may degrade or even become non-compliant. Consequently, this component is not suitable for any application involving the frequency band from 12 GHz to 18 GHz.

2. SA6H-01 Substitution Conclusion The SA6H-01 matches the original part number in basic parameters like attenuation value, power rating, and impedance. However, its frequency range (0–6 GHz) is the narrowest among the considered alternatives. This is a critical limitation: it can only guarantee its nominal attenuation performance and good impedance matching at frequencies up to 6 GHz. If used within the original design's full 6 GHz to 18 GHz band, it will result in inaccurate signal attenuation and increased reflection. This could severely impact system performance and potentially damage upstream components. Thus, its use is strictly limited to substituting for low-frequency applications only; it is not a viable universal replacement.
