Frequently asked questions
Which pin is which on the TO-92 package?
TO-92 JFET pinouts differ between manufacturers and batches, so confirm the drain, source and gate pins in the datasheet of your specific part before wiring it.
Can it be replaced by another part?
The listing names equivalents including BF245B, BF245C, 2N5457, 2SK117, MPF102, 2N5458, BF244A, BF256A, J113 and 2N3819. Compare the cutoff voltage and drain current in the datasheets before substituting, since they are not identical.
