Original Part
Alternative Part
1. SA6H-09 Substitution Conclusion
The SA6H-09 presents a key performance limitation as a substitute: its frequency range is limited to 0–6 GHz, whereas the original part (FMAT7466-9) supports 0–12 GHz. If your application circuit operates above 6 GHz, the SA6H-09 cannot guarantee its attenuation accuracy and impedance matching performance, which may lead to signal distortion or degraded system performance. However, if the operating frequency remains entirely within 6 GHz and all other parameters—such as attenuation value (9 dB), power rating (2 W), and interface type (SMA)—meet the requirements, it can serve as a same-brand, frequency‑reduced alternative.
2. LCAT1005‑09 Substitution Conclusion
The LCAT1005‑09 fully covers and exceeds the core electrical parameters of the original part. Its main advantage is an extended frequency range of 0–18 GHz, compared to the original part’s 12 GHz. It operates properly across the entire frequency band of the original part and provides additional frequency margin, resulting in better performance compatibility. Although the manufacturer differs (L‑com replacing Fairview Microwave), as long as the mechanical dimensions (SMA In‑Line Module) and interfaces are compatible, and there are no specific requirements for device “grade” or “certification” in the application environment, the LCAT1005‑09 represents a direct, performance‑equivalent or superior substitution.
