Procurement Notes
This component is officially obsolete and no longer manufactured by Qualcomm. Procurement must rely on the secondary market or authorized distributors holding remaining stock. Verify the authenticity of available units through official datasheets and manufacturer documentation. Ensure that any sourced inventory matches the exact part number to avoid compatibility issues with original designs.
Selection Notes
Designers should consider this component only if existing legacy hardware requires replacement with identical specifications. Due to its obsolete status, long-term supply continuity cannot be guaranteed. Evaluate alternative components from the same family or newer generations that offer similar electrical characteristics and form factors to ensure sustainable product lifecycles.
Part Context
The B39421 series represents Qualcomm's portfolio of RF front-end filters utilizing SAW technology. These components are engineered for mobile communications and IoT devices, providing essential signal conditioning. The B39421B3675U310 specifically targets the 415 MHz band, serving as a discrete filter solution within broader RF transceiver architectures.
Replacement Considerations
Public records indicate B39421R2702U310 as a similar substitute option. Verification of electrical compatibility and pin configuration is required before implementation.
