LSK389C SOIC-8 Group Buy

[Algar_emi]

Hi. Just starting this GB tentative to test if there is any interest in getting together to get better parts discount for the dual FET LSK389 from Linear Systems (see Linear Integrated Systems - Press Release), probably in SOIC-8 package. The part is a direct replacement for the discontinued 2SK389, used in multiples PASS LABS DIY design, like the ONO, Pearl, Discrete Op-Amp, just to name a few. If you want to make these projects, you need this dual FET. The few 2SK389 leftover in the world sell online for 12U$ ea and more, not counting the risk to get a counterfeit part.

I got samples and a price break for the LSK389. It is available and ready to ship. Price break are:

1-99: $3.00
100-999: $2.43
1000+: $2.19

It would be great to get at least 100 parts. We need to determine what grade to order, A (2.6-6.5ma), B (6-12ma) or C (10-20ma) (equivalent to previous 2SK389 grades GR, BL and V respectively) and the package SOIC-8 or TO-71. Personally, I would prefer the SOIC-8 package, but I'm flexible...Thanks...

grufti B 10 SOIC-8
EUVL B 20 SOIC-8 (but only @ $2.43)

So already 82 pieces B grade SOIC-8.

The other 3 guys want to switch types ?
Then we are done.

No interest in SO8: low power dissipation and a PITA to solder into existing circuits.

Your choice.
I don't see how you can twist the leads of the LS389 round to make it 2SK389 compatible.

I have a different application, so SOIC is fine for me.

Thank you for launching this project.

Subtotal A SOIC-8 = 20

Subtotal B TO-71 = 20

Can we close or still have to wait ?
Till when ?

Hi Patrick,

For me you can close the 1st round GB.

I'm looking for 10,5mA Idss so I would like to trade mines wich not have this value, somebody interest let me know the value he is searching so if I have the value that I don't need I'd like to trade for the value that I need.
