Procurement Notes
Verify the specific ordering suffix to confirm exact packaging and quantity specifications. Confirm availability status as manufacturing data may indicate end-of-life or limited supply conditions. Ensure compatibility with existing circuit designs regarding pinout and electrical parameters before procurement.
Selection Notes
Select this component for applications requiring a P-channel JFET with a 30V breakdown voltage. Consider the 300 Ohm on-resistance and 400mW power dissipation limits when designing thermal management solutions. Verify that the TO-92-3 package fits the PCB layout constraints.
Part Context
This part belongs to NXP's discrete semiconductor lineup, specifically within the JFET category. It serves as a fundamental active component for analog signal processing tasks where low noise and high input impedance are required. The TO-92 form factor ensures compatibility with legacy and modern through-hole assembly processes.
Replacement Considerations
Consult official substitution lists for equivalent P-channel JFETs with matching 30V ratings and TO-92 packages. Verify pinout compatibility and electrical parameter overlaps to ensure seamless integration without circuit redesign.
