The Great Search: Don’t overpay for out-of-stock parts, find Digi-Key alts! #TheGreatSearch #DigiKey #Adafruit @DigiKey @Adafruit

The great search is here to help you with your not-so-great parts shortage!

This week we’re looking at a twitter thread of folks commiserating over AWOL components.

Tobias is frustrated to see a 30 cent part, the TPS27081A go for $15 from unscrupulous brokers!

Maybe we can find some pin-compatible alternatives for them? Let’s go on The Great Search!

See the parts on Digi-Key

  1. Well, If you pick a specialized single-source golden hammer to pound in a penny nail, don’t complain if the hammer is out of stock some times! This TPS27081A part is just a high-side power path switch that’s dressed uo in an expensive tuxedo. Instead, simply use a jelly-bean dual NMOS logic level switch (yeah, PMOS transistors have lower Rdson, but they are more expensive and harder to source). I won’t even bother with a parametric search, off the top of my head look at the ubiquitous FS8205A, they have 18mOhm Rdson per transistor and cost qty.-10 USD $0.0575 each, and qty.-1,000 $0.0384 each. Shipping containers full of these tiny SOT-23-6L 6A switches are made every week. There are three regular sources for the FS8205A that I can see. Right now LCSC lists 10,000+ FS8205A ready to go. See here:

    And here is a datasheet:
