1. FMAT7466-9 Substitution Conclusion
The FMAT7466-9 matches the original part LCAT1005-09 in attenuation (9 dB), power rating (2 W), impedance (50 Ω), and package (SMA In‑Line Module). The difference lies in the frequency range: the FMAT7466-9 covers 0–12 GHz, whereas the original part is rated for 0–18 GHz. If the application system operates at or below 12 GHz, the FMAT7466-9 can be used as a direct replacement. However, if the frequency exceeds 12 GHz (e.g., within the 12–18 GHz band), the FMAT7466-9 may not provide effective attenuation, potentially leading to signal distortion or degraded performance. Therefore, substitution feasibility depends on the actual frequency requirements of the application.
2. SA26B-09 Substitution Conclusion
The SA26B-09 is identical to the original LCAT1005-09 in attenuation (9 dB), power rating (2 W), impedance (50 Ω), and package (SMA In‑Line Module). The key variation is the frequency range: the SA26B-09 supports 0–26 GHz, compared with 0–18 GHz for the original part. With its wider frequency coverage that fully encompasses and exceeds the 18 GHz upper limit of the original, the SA26B-09 offers better compatibility and performance margin in high‑frequency applications. Provided the connector configuration (such as SMA gender) is compatible with the system, the SA26B-09 is a viable drop‑in replacement and may even deliver superior high‑frequency stability and reliability.
