1. SA6-12 Substitution Conclusion
The SA6-12 is identical to the original part FMAT7611-12 in terms of attenuation value, power handling, impedance, and connector interface. The only difference lies in its frequency range, which is limited to 0–6 GHz, whereas the original part supports 0–18 GHz. If your application operates below 6 GHz, the SA6-12 can serve as a direct replacement. Since it is from the same manufacturer, performance consistency is assured. However, if the application involves the 6–18 GHz band, the SA6-12 cannot be used due to insufficient bandwidth, which may lead to signal distortion or significant deviation from the specified attenuation performance.
2. LCAT1000-12 Substitution Conclusion
The LCAT1000-12 matches the original part in key parameters such as attenuation value, power rating, impedance, and connector interface. The primary difference is similarly its frequency range, limited to 0–6 GHz compared to the original’s 0–18 GHz. For low-frequency applications within 6 GHz, this part can fulfill basic functional substitution. However, for requirements in the 6–18 GHz high-frequency range, its performance cannot be guaranteed. Moreover, due to the different manufacturer, RF characteristics such as VSWR and phase stability in the high-frequency band may differ from those of the original part. Verification in the actual circuit is necessary before determining suitability.
