On January 1, 2022, Impinj will begin the End-of-Life (EOL) process for the below listed Impinj Monza RAIN RFID tag chips.  

  • Impinj Monza 4i (IPJ-W1535-E00) 
  • Impinj Monza R6-A (IPJ-W1730-K00)  
  • Impinj Monza R6-B (IPJ-W1731-K00)

Impinj Monza R6-A and Monza R6-B tag chip EOL timeline: 



EOL process start date 

January 1, 2022 

Last date to place orders 

June 30, 2022 

Last shipment date 

December 31, 2022 

Due to supply constraints, there will be no last-time buy opportunity for Impinj Monza 4i. Impinj Monza 4E and Monza 4QT tag chips are drop-in compatible and are the recommended replacements for Monza 4i.   

Impinj recommends that partners transition to the Impinj M700 series of RAIN RFID tag chips to replace Impinj Monza R6-A and R6-B tag chips.  Impinj Monza MR-6A and MR6-B tag chip orders placed during the EOL period are non-cancelable and non-refundable. Otherwise, Impinj standard sales terms will be honored.
