Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging configuration. The standard part number may be available in bulk or tape-and-reel formats depending on the requested variant. Ensure that the selected version matches the required RoHS compliance status and lead-free plating specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage NPN transistor with moderate current handling is required for discrete switching tasks. The TO-92-3 package facilitates easy integration into through-hole designs. Verify that the 15 V collector-emitter rating aligns with the circuit's supply voltage requirements and that the 50 mA continuous current limit meets the load demands.

Part Context

This component belongs to the PN918 series of small-signal NPN transistors produced by Central Semiconductor Corp. The company specializes in discrete semiconductor devices, offering both standard and custom solutions. The PN918 represents a legacy silicon BJT design widely used in fundamental electronic circuits requiring reliable switching characteristics.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives such as the 2N3904 or BC547 if system constraints allow. Verify that substitute components meet or exceed the original voltage, current, and thermal specifications to ensure circuit integrity.
