1. LCAT1001-07 Substitution Conclusion
The LCAT1001-07 cannot serve as a full drop-in replacement for the original LCAT1000-07. The core difference lies in its operational frequency range, which is limited to DC-3 GHz, whereas the original part supports DC-6 GHz. If the signal frequency in the original application exceeds 3 GHz—such as in 5G, Wi-Fi 6E, or certain military/test bands—using the LCAT1001-07 will introduce unpredictable additional insertion loss, degraded VSWR, and even signal distortion, as its performance in this high-frequency range is neither specified nor guaranteed. It may only be considered as a cost-reduction or more readily available alternative in applications where the operating frequency is confirmed to be ≤3 GHz.
2. LCAT1002-07 Substitution Conclusion
The situation with the LCAT1002-07 is identical to that of the LCAT1001-07; it likewise cannot fully replace the original LCAT1000-07. The key limitation is also the frequency range (DC-3 GHz vs. DC-6 GHz). This discrepancy directly prevents its safe and reliable use in high-frequency circuits that may operate within the 3 GHz to 6 GHz band as originally designed. Its substitution conclusion aligns with that of the LCAT1001-07: it is only suitable for systems where the operating frequency is strictly limited to 3 GHz and below. Under this condition, its attenuation value, power handling capability, and interface configuration are consistent with the original part and can be interchanged.
