Mr. Hansen for sure was smarter as we all and has stocked up a lifetime supply of this parts long ago when they where still avaiable for 50 cents or so.

When they were still in production, we paid around $2 each for them in quantities of 1000 or so. When we heard they were stopping production, we bought 20,000 of each. This brought the price down to around $1 each, but was obviously a considerable investment. This was compounded by the fact that they were also discontinuing the A1349 and C3381 (same packaging issues). So we spent about $80,000 to get a 10 or 20 year supply.

Hopefully someone will come out with a replacement before we run out.

We have always used the BL parts as availability of the V parts was not as reliable. However, the V parts are preferable in every application I can think of. I would get them now while you can. The asking price is quite reasonable considering the situation. Linear Systems is advertising an equivalent for the K389, but nothing regarding a complementary device.

Linear Systems is having production problems with their P-ch product. The last time I was in contact, they were having yield issues. They are well aware that there is pent-up demand for P-ch devices and are doing their best to meet that demand.
When remains to be seen.

Well, I've been waiting for close to 15 years for either them or InterFET to make any sort of true complement. I'll believe it when I see it. In the meantime we still have tens of thousands of the Toshiba parts.

The one that I wished we hadn't missed out on were the NEC FETs, the J44 and K163. In some ways these were even better than the Toshiba parts. And Hitachi made some parts that were even quieter than the long-discontinued J72 / K147 Toshibas.

And I think that John Curl has some other parts that never even made it to production. But at least with the existing J74 / K170 and J103 / K246 Toshiba pairs, some excellent circuits can be built.

Terms and Condition

Hi again folks,

Actually we already reached 713 pieces, perhaps more in the near time, if we still can not reach 1000 pieces request, i hope we can still go on, but the price is raise a little to US$6.5 each, really i must buy a whole box content of 1000 pieces and the other BOX total is 2000 pieces for both of them.

payment must collect it firstly (and this takes times folks) paypal (PP fee 3%) preffered or via money bank transfer (mail me for further info about this, and the bank charge is on you)

CAUTION : for credit card buyer, must added 3% more for surcharge fee

according to Mr. Hansen, we agreed to the "V" version, so all 2sk389 and 2sj109 is "V" :smash:

shiping and handling is via registered mail and this cost US$6 worldwide until 100 grams

Hope we are all here understand the situation, and goodluck to all of you with this rare parts!! :smash:

Hi A',
you'll need to buy lots of conductive bags to send them out.
Would be nice if the N & P parts are separately bagged to save excessive handling at our end.
Allow something in your costs, say 3.2% uplift instead of just the 3% paypal fee.

OK, so with that S&C charge, I split from Korben69 and order by my own.

And I increase quantities to :
2SK389V (14)
2SJ109V (12)

BTW, I agree with AndrewT for seperate antistatic bags, and the surcharge.

I'll pay by Paypal when asked for payment.
I'm not in a hurry, so I can wait for the 1000 limit to be reached 😉

Cheers,
Trung
