1. SA6H-01 Substitution Conclusion The SA6H-01 is conditionally viable as a substitute. Its primary limitation is its operational frequency range (0–6 GHz), which is half that of the original component (0–12 GHz). If your application circuit operates above 6 GHz, using this part will introduce unpredictable additional insertion loss and performance degradation, potentially leading to signal distortion or failure to meet system specifications. Apart from this difference, its attenuation value (1 dB), power handling capacity (2 W), impedance (50 Ω), and interface type (SMA) are identical to the original. Equivalent substitution is only permissible when the system's maximum operating frequency is confirmed to be ≤6 GHz.

2. LCAT1005-01 Substitution Conclusion The LCAT1005-01 is fully viable and offers advantages as an electrical performance substitute. The key difference is its significantly wider frequency range (0–18 GHz) compared to the original part (0–12 GHz). It guarantees the specified attenuation accuracy and matching performance across the original component's entire operational bandwidth, with additional margin. All core parameters—attenuation value, power rating, impedance, and mechanical interface—are identical. While the manufacturer has changed from Fairview Microwave to L-com, requiring verification of procurement channels and quality control processes, from a purely technical specification standpoint, this part is a direct, performance-superior replacement.
