1. SA18H-09 Substitution Conclusion
The SA18H-09 can serve as a complete substitute for the original part LCAT1001-09. Their core parameters—attenuation value, power handling, impedance, and connector interface—are identical, ensuring direct electrical and mechanical compatibility within the original design specifications (DC-3GHz, 2W). The key difference lies in the frequency range: the SA18H-09 operates from 0–18 GHz, significantly wider than the original part's 3 GHz limit. This part maintains its specified attenuation accuracy and performance up to 18 GHz, typically due to more refined internal circuit design and materials. When used within the original system's operating band (≤3 GHz), it provides higher performance margin and reliability. This constitutes an "over-specified" yet harmless substitution, with the primary potential impact being higher cost.
2. FMAT1013 Substitution Conclusion
The FMAT1013 is also a fully compatible substitute for the original LCAT1001-09. It matches the original part in all key specifications—attenuation, power rating, impedance, and interface—meeting direct replacement requirements. The difference is its wider frequency range (0–6 GHz) compared to the original 3 GHz. It may offer improved performance and better consistency around the 3 GHz region, providing additional frequency performance margin for the original system. Compared to the SA18H-09, the FMAT1013's frequency coverage (6 GHz) aligns more closely with the original requirement (3 GHz). It ensures ample performance improvement (superior to the Original Part) while likely achieving a better balance between cost and ultra-high-frequency performance. This makes the FMAT1013 a cost-effective and reliable alternative to the Original Part.
