1. LCAT1002-01 Substitution Conclusion
Direct substitution of the LCAT1002-01 for the original part number is not viable, and its applicability is highly limited. The key discrepancy lies in its frequency range, which is specified only from DC to 3 GHz, significantly lower than the original part's DC to 12 GHz. Within the 3 GHz to 12 GHz band, the performance of this attenuator—including parameters such as attenuation accuracy and VSWR—will degrade severely or become non-functional, compromising signal integrity in that frequency range. It can only be considered a degraded-performance alternative for applications where the operational frequency is strictly confined below 3 GHz.
2. FMAT7620-1 Substitution Conclusion
The FMAT7620-1 is a fully compatible and superior electrical substitute for the original part. However, critical mechanical interface verification is mandatory. Its primary technical advantage is an extended frequency range of DC to 18 GHz, which fully encompasses and exceeds the original part's DC to 12 GHz specification. Within the original band, it provides equivalent or better high-frequency performance and stability. The documentation specifies its interface as "SMA MALE," whereas the original part uses a "JACK-PLUG" (i.e., SMA Female) connector. This represents an opposite physical connector gender. A direct swap would result in an inability to mate physically. Provided that the interface gender is confirmed to match or can be adapted via a suitable coaxial adapter within the system, the FMAT7620-1 is the superior replacement choice.
