1. LCAT1001-09 Substitution Conclusion
Not feasible. The LCAT1001-09 differs in that its frequency range is only DC–3 GHz, significantly lower than the original part’s DC–12 GHz. Across the high‑frequency band from 3 GHz to 12 GHz, key performance parameters such as attenuation accuracy, impedance matching (VSWR), and power handling cannot be guaranteed. This would likely lead to increased signal reflection, abnormal insertion loss, or device failure at higher frequencies. Consequently, it can only be used in applications where the operating frequency does not exceed 3 GHz and cannot serve as a full‑band replacement.
2. LCAT1000-09 Substitution Conclusion
Conditionally feasible; system frequency requirements must be evaluated. The frequency range of the LCAT1000-09 is DC–6 GHz, narrower than the original part’s 12 GHz but still covering common low‑to‑mid‑frequency bands. If your actual application operates below 6 GHz and does not demand tight performance margins at 6 GHz (such as attenuation flatness and VSWR), this part can serve as a direct replacement in terms of power rating, impedance, and connector interface. However, if the system operates within the 6–12 GHz range, this part cannot be used, as its performance would degrade significantly.
