1. SA18E-09 Substitution Conclusion The SA18E-09 can serve as a direct and complete substitute for the original part number. Its key technical parameters—including attenuation value (9 dB), frequency range (DC-18 GHz), power handling (2W), impedance (50 Ω), and connector type (SMA In-Line Module)—are fully aligned with the original part LCAT1006-09. Across the entire DC to 18 GHz spectrum, the signal attenuation characteristics, power handling capability, and impedance matching performance of the two components are theoretically identical. Therefore, they can be interchanged directly without concern for performance degradation or system mismatch.

2. FMAT7467-9 Substitution Conclusion The FMAT7467-9 is a conditional substitute with a key limitation. The primary deviation from the original specification is its frequency range, which is limited to DC-12 GHz, whereas the original part supports operation up to 18 GHz. If your application or test requirements involve the 12 GHz to 18 GHz frequency band, this part will not function correctly, exhibiting issues such as deviation from the nominal attenuation value and degraded VSWR. It is only a viable, parametrically compliant substitute (matching in attenuation, power, and interface) when the system's maximum operating frequency is definitively at or below 12 GHz. This difference directly dictates the scope of its applicability as a replacement.
