Procurement Notes
Verify the manufacturer designation as Fairchild Semiconductor or its successor entity onsemi during sourcing. Confirm the specific suffix 'BU' corresponds to the required tape-and-reel or bulk packaging variant if applicable. Ensure compliance with RoHS directives and check for lead-free status documentation provided by the supplier.
Selection Notes
Select this component when an NPN transistor with 25 V Vceo and 100 mA Ic is required. Compare against alternatives like the KSP10TA if different pinout or gain characteristics are needed. Verify that the 350 mW power dissipation limit meets the thermal requirements of the target application environment.
Part Context
The KSP10BU belongs to the KSP10 series of NPN transistors from Fairchild Semiconductor. This series is designed for general-purpose use in low-voltage, low-current applications. The device shares similar electrical characteristics with other members of the family but may differ in packaging or specific manufacturing lot details.
Replacement Considerations
Consult official cross-reference tools for equivalent parts. Potential substitutes include the KSP10TA or generic 2N3904 equivalents, subject to verification of pinout compatibility and exact electrical parameter matching against the original datasheet specifications.
