Original Part
Alternative Part
1. FMAT7467-10 Substitution Conclusion
The FMAT7467-10 matches the original part across most key specifications, but offers a narrower frequency range (0 Hz to 12 GHz compared to 0 Hz to 18 GHz for the original). If the application involves high-frequency signals above 12 GHz—such as in satellite communications, radar, or high-frequency test systems—this part cannot serve as a substitute. Beyond 12 GHz, its performance may degrade or fail, leading to signal distortion or potential equipment damage. For applications operating at or below 12 GHz, such as conventional wireless communication or intermediate-frequency circuits, it can be used as a viable replacement without concerns regarding attenuation, power handling, or impedance matching.
2. SA3SR-10 Substitution Conclusion
The SA3SR-10 provides identical attenuation, power rating, and impedance to the original part. However, its frequency range is limited to 0 Hz to 3 GHz, significantly lower than the original’s 18 GHz. This part is suitable only for low-frequency applications—such as audio, baseband signals, or low-rate data communication—and cannot be used in any scenario involving frequencies above 3 GHz, including microwave transmission, high-frequency testing, or broadband systems. If the system operates beyond 3 GHz, using the SA3SR-10 may result in inaccurate signal attenuation or thermal damage due to overheating. Therefore, it is not a drop-in replacement for the original part and should be restricted to specific low-frequency applications.
