The LM4041C12QDBZT comes in a standard SOT-23-3 surface-mount package (also listed as TO-236-3 / SC-59). Three pins: cathode, anode, and no-connect.
TI lists the LM4041C12QDBZT as Active. ROHS3 compliant. The base product number LM4041 covers a family of fixed shunt references.
The difference is the temperature range. The 'Q' suffix in LM4041C12QDBZT indicates the -40°C to 125°C automotive/industrial grade, while the 'I' variant (LM4041C12IDBZT) typically covers -40°C to 85°C. Confirm the exact spec from the TI datasheet for the 'I' variant.
Yes, if the generic reference is a shunt type with the same footprint (SOT-23-3) and the circuit can tolerate ±0.5% initial accuracy and 100 ppm/°C drift. The 12 mA output and 80 µA minimum cathode current are typical for this class.
Yes, it is ROHS3 compliant per TI's listing.
