Procurement Notes
Verify component authenticity through authorized channels due to the part's discontinued status. Confirm RoHS compliance details via official documentation before integration. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain reliability during assembly processes.
Selection Notes
Select this component for applications requiring a single NPN digital transistor with through-hole mounting. Verify that the 50V voltage rating and 100mA current capacity meet system requirements. Consider the SC-72 package dimensions for PCB layout constraints compared to surface-mount alternatives.
Part Context
This component belongs to the DTA143 series of pre-biased transistors from ROHM Semiconductor. The series offers various configurations including PNP types and different packaging options such as SOT-23 and SOT-416. The DTA143ESATP specifically denotes the NPN variant in the SPT through-hole format.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Due to the discontinued status, verify pin compatibility and electrical characteristics with potential alternatives from the same manufacturer or other suppliers offering equivalent digital transistor specifications.
