1. SA18SS-06 Substitution Conclusion The SA18SS-06 matches the original LCAT1001-06 part in all key specifications—attenuation, power handling, impedance, and package outline. Its operational frequency range, however, is extended to 0–18 GHz, significantly outperforming the original 0–3 GHz. This provides substantial performance margin and broader applicability in high-frequency applications. One critical physical constraint for substitution is the connector type: while the datasheet indicates SMA, the part number and certain descriptions suggest an SSMA interface. If the actual connector is indeed SSMA, it will be physically incompatible with the original SMA interface, preventing direct plug-and-play replacement. To use this substitute, an adapter or replacement of the corresponding connector/cable assembly is required.

2. FMAT7467-6 Substitution Conclusion The FMAT7467-06 aligns with the original LCAT1001-06 in all fundamental parameters—attenuation, power rating, impedance, and SMA connector package—ensuring direct physical compatibility and matching of basic electrical characteristics. Its primary technical advantage is an enhanced operational frequency range of 0–12 GHz, far exceeding the original 0–3 GHz. This part maintains drop-in replacement convenience while offering superior high-frequency response. It is an upward-compatible, directly interchangeable solution suitable for systems requiring higher operating frequencies or wider bandwidth margin, with no adverse trade-offs.
