Procurement Notes
Verify the specific suffix against official manufacturer documentation before procurement. Confirm that the requested variant matches the required resistance values and hFE ranking. Check the latest product lifecycle status on the manufacturer's website to ensure availability and compliance with current specifications.
Selection Notes
Select this component when a single NPN transistor with integrated biasing resistors is required for space-constrained designs. Ensure the 50 V voltage rating and 100 mA current capacity meet the circuit requirements. Verify that the internal resistor values align with the intended logic levels and drive currents.
Part Context
This part belongs to the UNR221x series of transistors with built-in resistors from Panasonic Electronic Components. The series offers various combinations of internal resistors and gain rankings to suit different digital circuit needs while maintaining a consistent physical footprint.
Replacement Considerations
Consult the official Panasonic replacement guide for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' devices without verifying pinout, electrical characteristics, and package dimensions.
