Original Part
Alternative Part
1. LCAT1000-09 Substitution Conclusion
The LCAT1000-09 can fully replace the original part SA6-09. Both devices are identical in all key performance parameters, including 9 dB attenuation, 0–6 GHz operating frequency, 2 W power handling, and 50‑ohm impedance. The physical interface is also the same—an SMA inline module—ensuring mechanical and electrical compatibility. The primary differences are the change in manufacturer from Fairview Microwave to L‑com, along with the corresponding supply chain source and brand warranty services. There is no degradation in core specifications, making this substitution both feasible and equivalent.
2. FMAT7620-9 Substitution Conclusion
The FMAT7620-9 serves as an upgraded, backward‑compatible replacement for the original SA6-09 in the vast majority of applications. The key improvement is its extended operating frequency range of 0–18 GHz, significantly wider than the original part’s 0–6 GHz. This device employs higher‑frequency design and materials, delivering performance equal to or better than the original part within 6 GHz while providing headroom for potential future high‑frequency system requirements. Provided the application frequency does not exceed 18 GHz and the cost is acceptable, this part represents a superior alternative.
