1. Substitution Conclusion for 32AS102-K20S3 The 32AS102-K20S3 matches the original part LCAT1000-20 in all key parameters—attenuation value, power handling, impedance, and package (20 dB, 2 W, 50 Ω, SMA connectorized module)—while offering a wider frequency range (0–18 GHz compared to 0–6 GHz). It not only fully covers the operational bandwidth of the original part but also supports higher‑frequency applications, delivering superior performance while remaining backward compatible. Therefore, direct substitution is feasible with no concern regarding frequency limitations.

2. Substitution Conclusion for SA3R-20 The SA3R-20 shares the same attenuation, power rating, impedance, and package as the original LCAT1000-20 (20 dB, 2 W, 50 Ω, SMA connectorized module); however, its frequency range is narrower (0–3 GHz versus 0–6 GHz). If the application involves operation within the 3–6 GHz band, this part will not function properly and may cause signal distortion or equipment damage. Substitution is only viable when the system’s operating frequency is strictly limited to below 3 GHz; otherwise, careful consideration is required.
