Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact electrical characteristics and packaging details. Ensure compliance with RoHS directives and check for any lifecycle status changes before procurement. Cross-reference part numbers carefully as minor suffix variations may indicate different specifications or packaging types.

Selection Notes

Select this component when space constraints require an ultraminiature footprint with integrated biasing. Verify that the 0.08 A collector current and 50 V voltage ratings meet the target circuit requirements. Consider the built-in resistor ratio of 1 for base drive calculations. Confirm thermal dissipation capabilities align with the application's power density needs.

Part Context

This transistor belongs to Panasonic's lineup of transistors with built-in resistors, specifically designed for digital circuits. The UNRF series offers a compact alternative to discrete transistor-resistor combinations, facilitating simplified board layouts and reduced assembly complexity in modern consumer and industrial electronics.

Replacement Considerations

Consult Panasonic's official cross-reference tools for verified substitutes. Ensure any replacement matches the ML3-N2 package dimensions and electrical ratings. Verify that the substitute maintains the same built-in resistor ratio if circuit compatibility is critical.
