1. SA6-06 Substitution Conclusion The SA6-06 can serve as a substitute for the original part LCAT1005-06, but only in applications where the operating frequency does not exceed 6 GHz. The primary difference lies in the frequency range: the SA6-06 covers 0–6 GHz, whereas the original part supports DC–18 GHz. Consequently, the SA6-06 is unsuitable for high-frequency signal processing between 6 GHz and 18 GHz. If the actual system frequency exceeds 6 GHz, substitution may result in degraded attenuation performance or functional failure. All other key parameters—including attenuation value (6 dB), power rating (2 W), impedance (50 Ω), and connector type—remain identical to the original part. Therefore, the SA6-06 is fully compatible in the lower frequency range.

2. FMAT1011 Substitution Conclusion The FMAT1011 can also replace the original part LCAT1005-06, subject to the same frequency limitation (0–6 GHz). The main distinction is again the frequency coverage: the original part supports up to 18 GHz, while the FMAT1011 is limited to 6 GHz. In applications above 6 GHz, this part cannot guarantee attenuation accuracy or stability. All other specifications—6 dB attenuation, 2 W power handling, 50 Ω impedance, and SMA interface—match the original. Thus, the FMAT1011 can be used as a direct replacement for frequencies below 6 GHz, provided the system frequency requirements are strictly evaluated.
