Original Part
Alternative Part
1. AT-110V Substitution Conclusion
The AT-110V can serve as a direct replacement. Its key specifications—attenuation of 10 dB, frequency range from DC to 18 GHz, power rating of 2 W, 50 Ω impedance, and SMA through‑hole package—are identical to those of the original LCAT1005‑10. Moreover, the manufacturer Hirose is a well‑established supplier of connectors and RF components, ensuring seamless substitution in terms of electrical performance, mechanical interface, and typical application scenarios. No circuit redesign or mechanical re‑layout is required.
2. M3933/30‑21N Substitution Conclusion
The M3933/30‑21N can be considered a high‑performance alternative, though with a notable difference in frequency coverage. Its primary advantage is the extended frequency range up to DC‑32 GHz, surpassing the original part’s 18 GHz limit, while all other parameters—attenuation, power handling, impedance, and interface—remain the same. This part is fully compatible with the original part in applications below 18 GHz and offers the potential for higher‑frequency use. However, if deployed in a system originally designed for ≤18 GHz operation, the wider bandwidth design may come with a cost premium; therefore, the necessity of this upgrade should be evaluated on a case‑by‑case basis.
