## Questions & Answers

**Q: Are these real or fake?**
A: My experience was that these are not mechanically the same as the BS170.  The source and drain pins 1 and 3 are reversed on this item compared with the BS170 specification on the data sheet.
It is possible that these were manufactured as 2N7000 transistors, which have this reversed gate and drain pinout / lead configuration, but inadvertently printed with the BS170 label on the flat face of the TO92 package housing, which is common to both types.
In theory, these could be soldered onto a PCB with the package body rotated 180 degrees to get the correct connections of the source, gate and drain pins.  However, that then leaves the question of whether this item has the electrical specification of a BS170, or a 2N7000, or of some quite different TO92 housed transistor with pin/lead 1 as source, 2 as gate and 3 as drain.
I can't say, because I sent the pack of 50 back for a refund after a couple had been destroyed in a PCB in which I assumed that I was getting devices with the correct BS170 pinout / lead configuration.
A transistor tester showed that these items are N-channel Enforcement mode MOSFETS, but my transistor tester is not sophisticated enough to she whether the items supplied can switch the specified 500mA of a BS170, or only the reduced 200mA maximum switching current of a 2N7000.
So, to answer your question, are they fake?: they definitely don't have the correct mechanical pin/lead configuration of a BS170, so in that respect they are implicated as fake.  If however they have the same electrical characteristics of a BS170 (which I can't comment on), then it may be possible to use them as BS170s as long as they are installed 180 degrees rotated.
Finally, these are much cheaper than other sources of BS170s, so it is possible that somewhere in the manufacturing. distribution, wholesale and retail supply chain, someone knows that these are not fully mechanically and electrically compliant with the specifications in the BS170 datasheet, and as such it is disappointing that they are still on sale, or that no note has been added to the item description about the above issues, given that I returned my order in the first week of May 2023 and another customer left a review on 13 May 2023 pointing out the same problem.
