1. FMAT7467-10 Substitution Conclusion The FMAT7467-10 can serve as a direct drop-in replacement for the LCAT1001-10, as both share identical key parameters—attenuation (10 dB), power rating (2 W), impedance (50 Ω), SMA interface, and mechanical outline. However, the FMAT7467-10 extends the frequency range to 12 GHz, significantly exceeding the original part’s 3 GHz upper limit. This gives the FMAT7467-10 superior broadband performance in high-frequency applications, while its low-frequency characteristics (e.g., DC–3 GHz) remain equivalent to the original part. If the system operates at or below 3 GHz, the electrical performance will be unchanged after substitution. Should future upgrades involve higher frequencies, this part provides additional headroom.

2. SA3SR-10 Substitution Conclusion The SA3SR-10 is a fully equivalent substitute for the LCAT1001-10. Both devices match exactly in attenuation (10 dB), frequency range (DC–3 GHz), power rating (2 W), impedance (50 Ω), and SMA interface structure, with no core performance differences. The SA3SR-10 can directly replace the original part without requiring circuit adjustments or raising compatibility concerns. It is suitable for all applications within the original system’s frequency requirement (≤3 GHz). Moreover, since it is sourced from the same manufacturer (Fairview Microwave), quality and reliability are expected to remain consistent.
