1. AT-101V Substitution Conclusion
From the perspective of core electrical and mechanical specifications, the AT-101V is a direct equivalent replacement for the LCAT1005-01. It shares identical attenuation value (1dB), frequency range (DC-18GHz), power handling capability (2W), characteristic impedance (50Ω), and interface form (SMA feed-through module). Within the target application band, the signal processing performance, power matching, and physical connectivity of the two parts will be completely consistent. The primary differences lie in the manufacturer brand change from L-com to Hirose, along with alterations in supply chain source, price, lead time, and specific quality control standards. However, these commercial and quality control variations typically do not affect its direct functional substitution within a circuit. Therefore, the substitution feasibility is high.
2. M3933/30-03N Substitution Conclusion
The M3933/30-03N matches the original part in key parameters such as attenuation value, power rating, impedance, and interface. Its most significant deviation is the extension of the operational frequency range from DC-18GHz to DC-32GHz. This part employs a higher-performance broadband internal circuit design and materials, enabling it to maintain excellent attenuation accuracy and VSWR performance up to 32GHz in the millimeter-wave band. For systems originally designed for applications only up to 18GHz, selecting this part provides substantial performance margin, theoretically offering higher reliability and consistency, though typically at a higher cost. For the original application frequency (≤18GHz), the electrical and mechanical feasibility for substitution is extremely high, and performance may even be superior, but the cost acceptability must be evaluated.
