1. LCAT1002-07 Substitution Conclusion For specific low-frequency applications below 3 GHz, it can serve as a downgraded substitute; however, its overall substitutability is limited, and it is not recommended as a general-purpose replacement. The key distinction lies in its frequency range of only 0–3 GHz, which is significantly narrower than the original part’s 0–12 GHz. This part is suitable only for systems operating at or below 3 GHz (such as common UHF and certain S‑band applications). If used in higher frequency bands covered by the original design (e.g., C‑band or X‑band), system failure or performance degradation will occur due to severe deviation from specified performance parameters, including insertion loss and VSWR.

2. FMAT7620-7 Substitution Conclusion It is a feasible upgrade replacement in terms of electrical parameters, provided that full mechanical interface compatibility is verified. The difference is its extended frequency range of 0–18 GHz, which exceeds the original part’s 0–12 GHz. This part maintains all specified performance across the original operating band and offers additional frequency margin, making it a performance upgrade. Successful substitution also requires ensuring that mechanical dimensions, connector type (SMA male), and form factor exactly match the original installation. While electrical performance is satisfied, mechanical compatibility remains the final critical factor for a successful replacement.
