Procurement Notes
Verify the specific suffix against official Panasonic documentation to confirm packaging type and lifecycle status. Confirm RoHS compliance requirements match the project specifications. Check for any maintenance or discontinuation notices on the manufacturer's website before finalizing procurement plans.
Selection Notes
Select this component when a PNP pre-biased transistor with a low base resistance ratio is required. Ensure the circuit design accommodates the specific R1/R2 values of 270 Ohms and 5 kOhms respectively. Verify that the -50 V voltage rating meets the system's maximum operating conditions.
Part Context
This part belongs to the UNR212x series of composite devices manufactured by Panasonic Electronic Components. The series includes various configurations of PNP transistors with different internal resistor ratios to suit diverse digital switching requirements.
Replacement Considerations
Direct substitutes within the same series include UNR212Y, which shares similar voltage and current ratings but utilizes different internal resistor values (3.1 kOhms and 4.6 kOhms). Verify pin compatibility and electrical characteristics before substitution.
