Procurement Notes
This component is designated as not recommended for new designs. Production continues solely to support existing customers. Engineers should verify availability through official ROHM channels and consider alternative active parts for new projects. Supply status may change without notice.
Selection Notes
Select this part only for legacy board upgrades or maintenance where the specific R1/R2 ratio and VMT3 footprint are mandatory. Verify that the 1kΩ input resistance and 10kΩ emitter-base resistance match the original schematic requirements. Confirm AEC-Q101 compliance is necessary for the target automotive environment.
Part Context
The DTC143XMFHAT2L belongs to the DTx series of pre-biased transistors manufactured by ROHM Semiconductor. It integrates an NPN bipolar junction transistor with two internal resistors into a single compact package. This integration reduces board space and assembly costs compared to discrete resistor-transistor combinations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the 'not recommended for new designs' status, engineers must evaluate functional equivalents with identical pinouts, electrical ratings, and automotive qualifications independently.
