Original Part
Alternative Part
1. AT-110V Substitution Conclusion
The AT-110V can directly replace the original part LCAT1006-10. Both devices share identical key technical parameters, including 10 dB attenuation, DC‑18 GHz frequency range, 2 W power handling, 50 Ω impedance, and SMA through‑hole package. This ensures seamless substitution in terms of electrical performance and mechanical interface, meeting all original design requirements. The differences lie in the manufacturer (Hirose Electric Co Ltd) and the associated supply chain change. Attention should be paid to lead time, cost, and potential minor variations in the manufacturer’s quality control standards, though these do not affect functional performance.
2. M3933/30-21N Substitution Conclusion
The M3933/30-21N can replace the original LCAT1006-10 and offers a higher frequency performance ceiling. The key distinction is the extension of the frequency range from DC‑18 GHz to DC‑32 GHz. This part maintains specified attenuation accuracy and performance up to 32 GHz, providing performance headroom for applications originally operating below 18 GHz. However, the cost may be correspondingly higher. All other critical parameters—power handling, impedance, and package—remain compatible with the original part. Substitution is therefore feasible and is particularly suitable for applications that may later require higher frequency expansion or where additional confidence in high‑frequency performance is desired.
