RF Transmitter Procurement Notes

Verify the specific frequency suffix (433.42) against regional regulatory requirements, as other variants in this series operate at different frequencies such as 433.92MHz or 434.50MHz. Confirm that the 6-DIP package aligns with your PCB footprint design. Ensure the 2.2V–3.6V supply voltage matches your system's power architecture before integration.

RF Transmitter Selection Notes

Select this module when a fixed-frequency ASK transmitter is required for simple remote control applications. It is suitable for designs needing moderate output power and low complexity. Consider alternative models like the RC-TXASK-433.92 if standard ISM band compliance is prioritized over the specific 433.42MHz requirement.

RF Transmitter Part Context

This component belongs to RadioControlli’s sub-1GHz ASK/OOK transmitter series. It shares architectural similarities with other modules in the family, differing primarily by its specific resonant frequency. The series includes variants for 433.92MHz and 434.50MHz, offering flexibility for different regional standards while maintaining consistent interface and performance characteristics.

RF Transmitter Replacement Considerations

Direct substitutes include RC-TXASK-433.92 and RC-TXASK-434.50, provided the frequency difference is acceptable for the application. These parts share identical packaging and functional interfaces.
