1. Qualification and Grade: The RBR2MM60BTFTR is explicitly marked as “Automotive” grade and is AEC-Q101 qualified; this information is absent from the RBR2MM60BTR’s parameter list, indicating it is a standard industrial- or commercial-grade product. AEC-Q101 qualification confirms that the device has undergone rigorous testing for automotive reliability requirements (e.g., temperature cycling, high-temperature reverse bias, moisture sensitivity). In automotive or other high-reliability designs, using a qualified component is mandatory. Without this certification, the device cannot meet the compliance and reliability standards of such designs. 2. Price and Positioning: The AEC-Q101 qualified RBR2MM60BTFTR is priced lower ($0.56000) than the non-qualified RBR2MM60BTR ($0.61000). This price discrepancy may be related to procurement channels, volume, or market strategy, and does not reflect typical manufacturing cost logic (qualified devices usually incur higher costs). This further reinforces that the fundamental distinction between the two lies in their qualification status, not in electrical parameters. During selection, certification requirements should be the primary consideration, not the listed price.
