RFID, RF Access, Monitoring ICS Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and potential end-of-life notifications is required before integration into new designs. Sourcing should focus on remaining inventory or authorized surplus channels if immediate replacement is necessary.

RFID, RF Access, Monitoring ICS Selection Notes

Designers should consider the obsolete status when selecting this part for new products. The MLX90109 series offers specific 125 kHz capabilities, but alternative active components may be required for long-term production. Evaluate pin compatibility and electrical specifications against newer Melexis offerings to ensure seamless transition without redesigning the entire RF interface.

RFID, RF Access, Monitoring ICS Part Context

The MLX90109 belongs to the MLX90109 series of wireless entry and go ICs manufactured by Melexis Technologies NV. This family focuses on low-frequency RFID solutions. The specific suffix -RE indicates reel packaging, while the base model defines the core transceiver functionality. It falls under the category of wireless and RF integrated circuits, specifically targeting tag and transponder implementations.

RFID, RF Access, Monitoring ICS Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Due to the obsolete status, engineers must consult official Melexis selection guides or distributor cross-reference tools for compatible active replacements that match the 125 kHz frequency and SOIC-8 package constraints.
