1. LCAT1002-07 Substitution Conclusion Proceed with caution for low-frequency applications only. The LCAT1002-07 is identical to the original SA6-07 part in terms of attenuation value, power handling, impedance, and connector interface. However, its core limitation is a reduced operational frequency range of DC-3 GHz, compared to the original's coverage up to 6 GHz. If your application involves signal frequencies above 3 GHz, substituting with the LCAT1002-07 will introduce additional, uncharacterized attenuation and performance degradation, such as increased VSWR. This can lead to non-compliance with system performance specifications or signal distortion. Therefore, it can only serve as a downgraded substitute for the original part in low-frequency applications below 3 GHz.

2. FMAT7620-7 Substitution Conclusion A direct and performance-enhanced substitute. The FMAT7620-7 matches the original SA6-07 part in all key parameters, including attenuation, power rating, impedance, and connector interface. Its operational frequency range is significantly wider, extending from DC to 18 GHz compared to the original's 6 GHz. Within the original part's entire operating band (0-6 GHz), the FMAT7620-7 guarantees its specified electrical performance. It remains functional even at higher frequencies, offering greater performance margin and reliability. Consequently, it serves as a direct, superior-performance replacement for the original part.
