1. LCAT1001-01 Substitution Conclusion
The LCAT1001-01 matches the original part FMAT7620-1 exactly in attenuation (1 dB), power rating (2 W), impedance (50 Ω), and package (SMA In-Line Module). These common parameters make it a potential direct substitute. The key difference lies in frequency range: the LCAT1001-01 only covers 0 Hz to 3 GHz, whereas the original part supports a wider 0 Hz to 18 GHz. If the application involves frequencies above 3 GHz—such as microwave communication, radar, or high‑frequency test systems—the LCAT1001-01 will not function properly and may cause degraded signal attenuation performance or even device failure. Conversely, if the application is limited to below 3 GHz (e.g., general RF or low‑frequency circuits), substitution is feasible. However, note that differences in manufacturer could introduce variations in quality or reliability.
2. LCAT1002-01 Substitution Conclusion
The LCAT1002-01 shares identical parameters with the LCAT1001-01, including attenuation (1 dB), power rating (2 W), impedance (50 Ω), and package (SMA In-Line Module). Therefore, its substitution conclusion is the same as that for the LCAT1001-01. The critical distinction remains the frequency range: the LCAT1002-01 is limited to 0 Hz to 3 GHz, while the original FMAT7620-1 covers 0 Hz to 18 GHz. This means substitution is only viable for low‑frequency applications (≤3 GHz), such as consumer electronics or baseband signal processing. For high‑frequency needs—like satellite communications or broadband instrumentation—the frequency mismatch of the LCAT1002-01 would create a performance bottleneck, making it unsuitable as a replacement. When making a decision, the system’s frequency requirements must be rigorously evaluated to avoid compatibility issues.
