1. LCAT1000-06 Substitution Conclusion This component can serve as a downgraded replacement provided the frequency requirement is met. The key difference lies in its frequency range (0–6 GHz), which is only half that of the original part (0–12 GHz). Performance parameters such as attenuation accuracy and VSWR are neither calibrated nor guaranteed in the 6 GHz to 12 GHz band. If the application frequency exceeds 6 GHz, it may result in inaccurate signal attenuation, increased reflection, and degraded system performance. Therefore, this substitute is only suitable for applications where the operating frequency is confirmed not to exceed 6 GHz.

2. LCAT1001-06 Substitution Conclusion Substitution is not recommended; it is only applicable to specific low‑frequency scenarios. The primary limitation is again the significantly narrower frequency range (0–3 GHz) compared to the original part (0–12 GHz). It operates reliably only below 3 GHz. For mid‑ to high‑frequency signals (3–12 GHz) covered by the original design, unpredictable attenuation errors and impedance mismatch may occur, potentially leading to signal distortion and measurement inaccuracies. Hence, this part cannot be substituted unless it is confirmed that the system operates exclusively below 3 GHz.
