RF Transmitter Procurement Notes

The MICRF102BM is officially discontinued and no longer stocked by major distributors such as DigiKey. Verification of availability should focus on identifying direct substitutes like the MICRF102YM. Ensure that replacement components meet the same electrical specifications and package requirements to maintain system compatibility without redesign.

RF Transmitter Selection Notes

Select this component only if legacy support for the 300-470MHz band and ASK/OOK modulation is required. Consider the discontinuation status when planning long-term production. Verify that the 8-SOIC package fits the existing PCB layout. Evaluate the MICRF102YM as a potential direct replacement if available, ensuring it matches the original pinout and performance characteristics.

RF Transmitter Part Context

The MICRF102 series belongs to Microchip's portfolio of single-chip RF transmitters utilizing proprietary QwikRadio technology. Originally developed by Micrel before its acquisition, these devices target simple, cost-effective remote control solutions. The MICRF102BM specifically denotes the tape-and-reel or tube packaged variant within the 8-SOIC form factor, distinct from other suffixes that may indicate different packaging or temperature grades.
