1. LCAT1000-10 Substitution Conclusion
The LCAT1000-10 matches the original part 32AS102-K10S3 in attenuation value, power handling, impedance, and package outline. However, its frequency range is limited to 0 Hz to 6 GHz, whereas the original part supports 0 Hz to 18 GHz. In applications involving signals above 6 GHz—such as microwave communications, radar, or test systems—the LCAT1000-10 will either fail to operate or exhibit degraded attenuation performance, thus limiting its suitability as a substitute. It may only be considered for temporary or cost-sensitive replacement if the system’s operating frequency is strictly confined to below 6 GHz. Even then, the unspecified grade and qualification status from manufacturer L‑com should be evaluated to ensure reliability requirements are met.
2. FMAT7620-10 Substitution Conclusion
The FMAT7620-10 aligns completely with the original part 32AS102-K10S3 in attenuation, frequency range (0 Hz–18 GHz), power rating (2 W), impedance, and physical footprint, with no apparent technical discrepancies. From a parametric standpoint, the FMAT7620-10 can serve as a direct drop‑in replacement for broadband high‑frequency applications such as lab testing or RF front‑end designs. That said, potential differences in unspecified grade and qualification from manufacturer Fairview Microwave—such as environmental robustness or operational lifetime—should be considered. It is recommended to verify performance consistency with the original Rosenberger part in the actual application before final deployment.
