1. LCAT1002-06 Substitution Conclusion The LCAT1002-06 can serve as a replacement for the original part LCAT1005-06, but only in applications where the operating frequency does not exceed 3 GHz. The key difference lies in the frequency range: the LCAT1002-06 supports 0 Hz to 3 GHz, whereas the LCAT1005-06 supports 0 Hz to 18 GHz. If the system operates above 3 GHz, the LCAT1002-06 may fail to maintain the specified attenuation accuracy and signal integrity, leading to degraded high‑frequency performance, signal distortion, or attenuation drift. This can compromise the reliability of the RF link. Therefore, substitution must be strictly evaluated against the frequency requirements.

2. LCAT1000-06 Substitution Conclusion The LCAT1000-06 can replace the original part LCAT1005-06, but only for applications up to 6 GHz. The primary variation is in frequency coverage: the LCAT1000-06 operates from 0 Hz to 6 GHz, while the LCAT1005-06 covers 0 Hz to 18 GHz. In the 6 GHz to 18 GHz range, the attenuation characteristics of the LCAT1000-06 may deviate from nominal values, introducing insertion loss variation or impedance mismatch. This can degrade high‑frequency signal processing quality and overall system performance. Hence, substitution must ensure the actual operating frequency remains below 6 GHz to avoid potential risks.
