Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Honeywell Aerospace. Procurement must rely on remaining stock from authorized distributors or secondary market sources. Verify RoHS compliance status and check for Product Change Notices (PCN) regarding lead frame plating or pad dimensions before integration into new designs.

Selection Notes

Engineers should evaluate the 31.5dB fixed attenuation profile against system link budget requirements. The 0.5dB step resolution offers fine-grained control suitable for precision calibration tasks. Consider the 50 Ohm impedance match for standard RF infrastructure compatibility and ensure the 24-VQFN thermal pad soldering process aligns with available assembly capabilities.
