1. SA18E-09 Substitution Conclusion Fully viable. The SA18E-09 is identical to the original LCAT1002-09 in all key parameters—attenuation value, power rating, impedance, and connector interface. However, its operational frequency range (DC-18 GHz) significantly exceeds that of the original part (DC-3 GHz). The SA18E-09 can therefore perfectly replace the original component across all system frequencies, while also providing performance headroom for higher-frequency applications. This constitutes a "drop-in upgrade" substitution, with no risk of degradation in electrical performance or mechanical compatibility.

2. FMAT7467-9 Substitution Conclusion Fully viable. The FMAT7467-9 matches the original LCAT1002-09 in all critical specifications—attenuation, power handling, impedance, and interface. Its operational frequency range (DC-12 GHz) is also notably wider than the original's DC-3 GHz. This indicates that the FMAT7467-9 meets all original system requirements while offering extended bandwidth capability. Substitution will not compromise the RF performance of the system; instead, it provides enhanced frequency adaptability. This qualifies as a direct performance‑enhancing replacement.
