Alternative Part
1. FMAT7467-10 Substitution Conclusion
The FMAT7467-10 matches the original part exactly in attenuation, power handling, impedance, and connector interface. However, its operational frequency range (0–12 GHz) is significantly narrower than that of the original component (0–18 GHz), which is the primary limitation for substitution. If your application operates below 12 GHz, the FMAT7467-10 is fully compatible and can serve as a direct replacement. For systems that utilize the 12–18 GHz band, this part cannot be used as it exceeds its specified frequency range. Such operation may lead to severe degradation in attenuation performance, increased VSWR, and potential device damage. Therefore, it is critical to verify the actual operating frequency band of the system before substitution.
2. SA3SR-10 Substitution Conclusion
The SA3SR-10 aligns with the original part in basic parameters such as attenuation value, power rating, and impedance. Nevertheless, its key operational frequency range (0–3 GHz) is far lower than that of the original part (0–18 GHz), creating a fundamental barrier to substitution. This part is only suitable for low-frequency applications below 3 GHz, such as certain commercial communications or legacy instrumentation. For any system operating above 3 GHz—including most modern microwave communications, radar, and high-frequency test systems—the SA3SR-10 is completely unsuitable. It would severely limit system bandwidth and cause failure in high-frequency signal processing. Consequently, it cannot serve as a general-purpose replacement for the original part and has a very narrow range of applicability.
