1. LCAT1002-06 Substitution Conclusion Direct substitution is not recommended. While the LCAT1002-06 matches the original part FMAT1011 in key parameters such as attenuation value, power handling, and impedance, its operational frequency range is limited to 0–3 GHz, which is significantly narrower than the original part’s 0–6 GHz range. This limitation is critical: if the application frequency exceeds 3 GHz, the attenuator cannot guarantee its nominal attenuation accuracy, impedance matching, or power rating. This may lead to signal distortion, measurement errors, or device damage. Therefore, the LCAT1002-06 should only be considered for applications strictly operating below 3 GHz.

2. LCAT1000-06 Substitution Conclusion Full substitution is acceptable. The LCAT1000-06 is identical to the original part FMAT1011 in all key electrical specifications, including 6 dB attenuation, 2W power handling, 50‑ohm impedance, and the essential full operating frequency range of 0–6 GHz. Mechanically, both share the same SMA through‑hole package. The devices are directly interchangeable in terms of electrical performance—such as frequency response, VSWR, and power handling capability—as well as physical connectivity. The only distinction lies in the manufacturer branding, making the LCAT1000-06 a functionally equivalent drop‑in replacement in practical applications.
