Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A' against official Microchip or NXP documentation to confirm exact electrical tolerances, as generic listings may not distinguish between standard and enhanced variants. Ensure the TO-18 package style matches the design requirements. Confirm lead-free status if RoHS compliance is mandatory for the target assembly process.

Single Bipolar Transistors Selection Notes

Select this component when a hermetically sealed metal package is required for harsh environments. The TO-18 form factor offers superior heat dissipation compared to plastic packages. Consider the 0.4 W power limit and 175 °C max temperature when designing thermal management solutions for continuous operation.

Single Bipolar Transistors Part Context

This part belongs to the legacy small signal transistor family originally manufactured by Motorola and now managed by NXP. It serves as a fundamental discrete semiconductor component for analog circuit design. The TO-18 package is a standard through-hole format often used in military and industrial equipment where reliability is critical.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference guides for equivalents such as the 2N3904 in different packages or other NPN transistors with similar hFE and power ratings. Verify pinout compatibility before substitution.
