1. LCAT1000-03 Substitution Conclusion
The LCAT1000-03 matches the original part 32AS102-K03S3 in attenuation (3 dB), power rating (2 W), impedance (50 Ω), and package (SMA‑inline module). The key difference lies in the frequency range: the LCAT1000-03 only supports 0 Hz to 6 GHz, whereas the original part covers 0 Hz to 18 GHz. In applications operating above 6 GHz—such as microwave communications, radar, or high‑frequency test systems—the LCAT1000-03 will not provide accurate attenuation performance. This could lead to signal reflection, increased insertion loss, or degraded system performance. However, for low‑frequency applications below 6 GHz, including Wi‑Fi, mobile communications, or general RF circuits, it can serve as a direct drop‑in replacement without concerns over power or impedance matching.
2. LCAT1001-03 Substitution Conclusion
The LCAT1001-03 shares the same attenuation, power rating, impedance, and package as the original part 32AS102-K03S3. The critical deviation is its narrower frequency range, covering only 0 Hz to 3 GHz compared to the original’s 0 Hz to 18 GHz. The LCAT1001-03 is suitable solely for low‑frequency applications such as broadcasting, two‑way radios, or basic RF links. If used above 3 GHz—for example in 5G, satellite communications, or high‑frequency instrumentation—its attenuation characteristics may deviate from the nominal values, potentially causing signal distortion or system instability. This component should only be considered as a substitute in scenarios strictly limited to 3 GHz and below; otherwise, a part with a higher frequency range is recommended to ensure performance compatibility.
