1. LCAT1001-10 Substitution Conclusion The LCAT1001-10 is only applicable within the 0–3 GHz frequency range, whereas the original part FMAT7466-10 supports 0–12 GHz. The difference lies in the frequency bandwidth. In applications involving RF signals above 3 GHz, the LCAT1001-10 may experience performance degradation, increased reflection, or failure due to its frequency limitation. Therefore, it can only serve as a substitute for the original part in low-frequency applications (≤3 GHz). The actual system frequency requirements must be evaluated before substitution.

2. LCAT1000-10 Substitution Conclusion The LCAT1000-10 supports a frequency range of 0–6 GHz, which is still lower than the original part’s 0–12 GHz range—again due to bandwidth difference. Within the 6–12 GHz high-frequency range, the LCAT1000-10 cannot guarantee the specified attenuation accuracy and impedance matching, potentially introducing signal distortion or power loss. Thus, it is only suitable for substitution in mid-to-low frequency applications (≤6 GHz). It is necessary to verify that the system’s maximum operating frequency does not exceed 6 GHz.
