Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm internal resistance values and marking symbols. Confirm availability status as product lines may be discontinued or subject to change without notice. Request the latest Product Standards before final design implementation to ensure specifications remain current.

Selection Notes

Select this component when a pre-biased NPN transistor with equal base and emitter resistance ratios is required. Ensure the 10 kΩ resistor configuration matches the target logic interface requirements. Verify that the 150 MHz transition frequency meets the signal processing speed needs of the application.

Part Context

This part belongs to the UNR921xJ series of transistors with built-in resistors manufactured by Panasonic Industry. The series offers various resistor combinations tailored for different digital logic applications. The '0L' suffix typically denotes tape-and-reel packaging, while the 'J' indicates the specific resistor configuration within the family.

Replacement Considerations

Consult the manufacturer's cross-reference list for verified substitutes. Ensure any replacement maintains the same NPN polarity, 50V rating, and identical 10kΩ/10kΩ resistor configuration to guarantee functional compatibility in existing designs.
