RF Receivers Procurement Notes

Verify the specific suffix designation when ordering, as packaging variations such as CT may indicate bag packaging rather than standard box quantities. Confirm that the required sensitivity level aligns with your system design, as datasheets may list values ranging from -109dBm to -112dBm depending on test conditions. Ensure the supplier provides official documentation to validate the active part status and electrical specifications before finalizing procurement.

RF Receivers Selection Notes

Select this component when a dedicated superheterodyne receiver is preferred over direct conversion types for improved selectivity and image rejection. The wide supply voltage range allows compatibility with both 3.3V and 5V logic systems without additional regulation. Consider the through-hole package if mechanical robustness or manual assembly is required. Verify that the 433.92MHz frequency band is permitted in your target region for regulatory compliance.

RF Receivers Part Context

This module belongs to the RadioControlli family of RF receiver components, which includes variants like the RCBRX-434. While similar models may utilize PLL synthesizers, the RCRX1-434 specifically employs a crystal oscillator for its superheterodyne operation. It serves as a specialized alternative to general-purpose AM receivers, offering optimized performance for fixed-frequency industrial and consumer applications.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users requiring a replacement should verify pinout compatibility and electrical parameters against the original datasheet. Cross-referencing with other AM superhet modules requires careful validation of sensitivity and supply voltage ranges to ensure functional equivalence.
