RF Detectors Procurement Notes

Verify availability status carefully as the part is listed as obsolete. Confirm package compatibility and lead times with authorized distributors. Ensure design-in decisions account for end-of-life implications and potential long-term supply constraints.

RF Detectors Selection Notes

Consider the 3V supply requirement and 4 mA current consumption when designing power management circuits. Evaluate the 10-SOP footprint against PCB layout constraints. Assess the 73 dB noise figure against system sensitivity requirements for FM reception.

RF Detectors Part Context

This component belongs to onsemi's RF receiver and detector family, specifically targeting FM IF system integration. It serves as a specialized solution for demodulating intermediate frequency signals in consumer electronics and communication devices requiring compact surface-mount implementations.

RF Detectors Replacement Considerations

No public confirmed substitute part numbers are available. Designers should evaluate pin-compatible alternatives or redesign circuits to accommodate newer generation RF receiver ICs from onsemi or other manufacturers.
