Attenuators Procurement Notes

Verify the current manufacturing status as this component is listed as obsolete in some distributor catalogs. Confirm availability of parametric equivalents if direct supply is unavailable. Ensure the replacement part matches the 20 dB attenuation value, 50 ohm impedance, and N-type connector specifications required for your specific application.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation is required within a 50 ohm system operating up to 13 GHz. Consider the physical size and connector type compatibility with existing PCB or cable assemblies. Evaluate alternative parts from other manufacturers if Hirose supply is restricted due to obsolescence.

Attenuators Part Context

This model belongs to Hirose's line of connectorized attenuators designed for N, BNC, and TNC interfaces. These components are engineered to provide reliable signal control in RF environments. The series offers various attenuation values to suit different circuit requirements while maintaining consistent impedance characteristics.

Attenuators Replacement Considerations

Molex part number 0732870450 is identified as a parametric equivalent substitute. Verify that the alternative component meets the same 20 dB attenuation, 50 ohm impedance, and 13 GHz frequency specifications before integration.
