Procurement Notes

This component is officially discontinued and no longer manufactured by Qualcomm. Sourcing new original units may be difficult or impossible through standard distribution channels. Engineers should verify availability with authorized distributors or consider alternative replacement parts that meet the same electrical specifications and form factor requirements for current production designs.

Selection Notes

Selection is limited due to the discontinued status of this specific part number. Designers requiring SAW filters for similar frequency bands must evaluate alternative components from the manufacturer's current portfolio. Compatibility checks regarding pinout, footprint, and insertion loss are essential when substituting this obsolete component with newer generations of RF filters.

Part Context

This device belongs to Qualcomm's RF Front-End (RFFE) filter portfolio, which includes various discrete and embedded solutions. These products typically leverage technologies such as ultraSAW or TC-SAW to address challenges in mobile, PC, and IoT applications. The B39800 series represents earlier iterations of these acoustic filtering solutions.
