Procurement Notes

Verify the manufacturer origin carefully, as Sanyo Semiconductor operations have undergone corporate restructuring and brand transitions. Ensure the specific suffix matches the required tape-and-reel or bulk packaging configuration. Confirm RoHS compliance status through the official datasheet provided by the current rights holder or authorized distributor before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage PNP transistor with moderate current handling is required for surface-mount designs. Compare the -12 V collector-emitter rating against circuit supply voltages to ensure adequate headroom. Evaluate the 50 mA current limit against peak load requirements to prevent thermal overstress during continuous operation.

Part Context

This transistor belongs to the broader family of small-signal bipolar devices historically manufactured by Sanyo Electric. These components are widely utilized in consumer electronics and industrial control systems where compact form factors and reliable switching characteristics are essential for modern printed circuit board architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the verified source material. Engineers should consult official cross-reference databases or contact authorized distributors for equivalent PNP transistors with matching voltage, current, and package specifications.
