RF Transmitter Procurement Notes
Verify end-of-life status prior to procurement as the manufacturer has scheduled this component for obsolescence. Confirm that existing inventory or last-time buy quantities meet project requirements. Ensure alternative sourcing channels are identified if long-term supply stability is critical for the application lifecycle.
RF Transmitter Selection Notes
Select this component only when specific 435 MHz operation and ASK/FSK modulation align with system requirements. Consider the limited thermal operating range and low voltage constraints during circuit design. Evaluate the availability of replacement parts due to the discontinued status before finalizing the bill of materials.
RF Transmitter Part Context
This part belongs to the TDx7100 series of radio frequency transmitters from Infineon Technologies. It serves as a specialized integrated circuit for simple wireless transmission tasks, distinct from complex multi-channel or high-power RF solutions. The component represents a legacy solution within the company's wireless portfolio.
RF Transmitter Replacement Considerations
No public confirmed substitute part numbers are available. Due to the end-of-life status, engineers must identify functional equivalents independently based on frequency, modulation type, and package compatibility.
