1. SA18E-09 Substitution Conclusion
The SA18E-09 can serve as a fully equivalent drop-in replacement for the original LCAT1005-09 part. A comparison of technical parameters confirms that both share identical core specifications, including attenuation value (9dB), frequency range (DC-18 GHz), rated power (2W), impedance (50Ω), as well as connector type and package (SMA In-Line Module). The SA18E-09 is compatible with the original part in all electrical performance and mechanical interface aspects. It provides identical attenuation performance and power handling capability across the entire DC to 18 GHz band, enabling a direct replacement.
2. FMAT7467-9 Substitution Conclusion
The FMAT7467-9, as a potential substitute, has critical performance limitations, and its substitution feasibility is strictly dependent on the application frequency band. The primary discrepancy between this part and the original lies in the frequency range (0 Hz ~ 12 GHz vs. 0 Hz ~ 18 GHz). In the high-frequency band from 12 GHz to 18 GHz, the performance of the FMAT7467-9—specifically its attenuation accuracy and VSWR—cannot be guaranteed and may degrade significantly. It is only suitable for replacing applications operating at or below 12 GHz. This part is not applicable if the system's operational frequency involves or approaches 18 GHz.
