1. LCAT1000-06 Substitution Conclusion
The LCAT1000-06 can serve as a conditional substitute for the original FMAT7620-6 part. Both units are identical in terms of attenuation value, power rating, impedance, and connector interface. The core difference lies in the frequency range: the original part supports DC-18 GHz, whereas the LCAT1000-06 is limited to DC-6 GHz. Therefore, this substitution is viable if your actual application frequency is below 6 GHz. However, for signals within the 6 GHz to 18 GHz band, this part will either fail to function or cause signal anomalies, making it an unsuitable replacement.
2. LCAT1001-06 Substitution Conclusion
The LCAT1001-06 presents a low feasibility and high-risk option as a substitute for the original FMAT7620-6. While its basic parameters—such as attenuation, power handling, impedance, and interface—are matched, there is a significant discrepancy in frequency range. The original part covers up to 18 GHz, but the LCAT1001-06 is only rated for DC-3 GHz. This unit is solely applicable for low-frequency operations below 3 GHz. At any operating frequency above 3 GHz, it will introduce unpredictable attenuation errors and performance degradation, which carries a high probability of causing system failure. Consequently, it is not recommended as a general-purpose substitute.
