RF Transmitter Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Microchip Technology. Procurement is restricted to existing stock or third-party distributors. Verify part authenticity carefully due to potential availability of refurbished units. Check expiration dates and storage conditions if sourcing from non-direct channels. No new production runs are scheduled.

RF Transmitter Selection Notes

Engineers should consider this part only for maintenance of legacy designs. New projects must avoid this obsolete component. Evaluate alternative transmitters that support modern manufacturing standards. Ensure any substitute matches the required frequency band and modulation type. Review pin compatibility if replacing in existing footprints.

RF Transmitter Part Context

The MICRF103YM TR belongs to Microchip's historical portfolio of low-cost RF transmitters. It was commonly used in early automotive keyless entry systems. The device represents an earlier generation of integrated RF solutions before more advanced multi-band options became standard. Its discontinuation reflects industry shifts toward higher integration and lower power requirements.
