In Search Of Intersil ISL21009BFB850Z Voltage Reference IC

[t1d]

Intersil ISL21009BFB850Z, Precision 5V Voltage Reference ±0.5mV 3ppm/ºC.
It doesn't seem to be available any longer in the USA.
I am hoping someone has some in their stock that they can share, swap or sell.
Thanks for your help...

Good source of parts: https://www.utsource.net/search.aspx?keyWords=ISL21009BFB850Z&page=1

I recently placed another order from them for other stuff. There RFQ is quick and real and small quantities are OK.

I have also had good luck with Utsource.net but it could be a long delay in delivery times.
Working from memory, I think ISL21009 series was discontinued in favor of better specs; ISL20190 series which added a built in trim pin.
Should be able to use it with minor modification. Consult datasheets.

Thanks, VTech... I look it up on Digikey... Closest part number was 21090... But, it looked like the specs might not be as good... It's late, here, so I did not give it a thorough reading... Good lead...

If you look here: https://www.digikey.com/product-sea...t=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25 the MOQ is 1, but non-stock.

Thank you for your continued help. This particular part number is now list as "obsolete." So, with a zero stock level, they will not fill the order. The newer model number was a great tip and I hope to find the replacement. Thanks!
