Hi , i received a quote for a 2N5565 dual n channel jfet.

No.	Part No.	MFG	PACKAGE/DESCRIPTION	Qty	Unit/Price	Lead Time
1	2N5565	VISHAY	TO-71 Lead free/RoHS Compliant , Bulk new parts - Samples Required	15	$ 15.0000	1-2 days
TOTAL: (USD) 225.00​

I then received a follow up email stating the part is "refurbished" and maybe i could make an offer.
This puzzled me.
How can you refurbish this part , other than change the markings on the case.
Starting to smell.
Any thoughts.

 

Starting to smell.

Yup, sounds (old) fishy to me too.

thanks for the reply , any thoughts on the refurbish bit .

I suspect that these parts are old and have simply been rechecked against their datasheet parameters.

 

Cannibalised parts.

 

Know as "pulls" - second-hand parts.
If you are buying them from China or Ebay, then they are much more likely to be genuine than anything claimed to be new.
There is a slight chance they might be faulty, but whenever I have bought obsolete parts they have been genuine and working.

Hi , thanks for all the replies.
The quote is from China.
Maybe their idea of refurbish is genuine "pulls" and "rechecked against datasheet parameters"
Best regards.

 

Hi , All.
I sent this email:

Hi Leon , could you please clarify what you mean by "refurbished".
Are these parts genuine Vishay parts?
Best regards

This is what came back:

Yes, that's genuine Vishay part, but there are only the second hand.
"refurbished" means it's used, and the vendor re-sanding and polishing, we can provide the picture for your confirm before shipment.

Feel a little more confident.
The price asked was $15USD----ouch!
Will make offer as requested buy seller.

Thanks Ian0 , i inquired about their LS841 , but as yet i haven't heard back.
I don't think they are keen to deal with minions like me from down under.
The last time , some years ago i had get a forum member from the US to buy them and then send them to me.
Thanks for your interest.
Best regards

 

On-semi have a few JFET pairs

for those of us with sensible budgets!
Unfortunately, they are all common-source.

Some reputable, honest dealers offer items as "removed from equipment, qualifying it as either used or unused. Sometimes these are great deals. I once bought 20 12 volt/ 8 amp linear power supplies , "removed from new equipment" for $10 each. I quickly sold most of them, some for much more than I paid, and kept those that I wanted. So there are some good deals and some not so good deals.

Thanks MisterBill2 , it' a minefield.

 

Hi , i leapt into the unknown and purchased these.
Fingers crossed.

You'd think it would be rather tricky to fake something in a metal can with 6 leads!

 

But it would not be such a trick to pull such a device out of a board or socket and re-tin and/or re-shape the leads so it looks like new. That is done all the time. Beware! Maybe just get a couple of samples first so you can test them and maybe de-lid on to see if it is the real thing or not.

 

It certainly looks unused, the leads do not appear to have been trimmed.
