Can't be true.  The Chairman says there is no inflation.  Gas up over a $ a gallon is just your imagination too. rofl >!

Inflation has gone through the roof worldwide. They reckon things won’t settle till the third quarter of next year. You were fortunate to find a competitive alternative. Asian suppliers are really feeling the brunt of shortages owing to the effects of the pandemic.

PIC12F1822 from $0.91 (09/09/2020) to $1.29 each at 100 pieces (11/14/2021)
PIC16F1823 from $1.02 (12/09/2020) to $1.47 each at 100 pieces (11/14/2021)

Yeah, only 6.2% inflation.

Be thankful you can even get them! Let this truck driver tell you why, https://bit.ly/3Fhkc8u

I had read that maybe a week ago.  But in this case it is a production problem.  Mouser shows 122 stock for the 12F1822 DIP, and I ordered them all.  Next shipment isn't due until next June.

There are plenty of the SMD version available, but I used the DIP to make it easy to do a firmware upgrade.  For example, the noise monitor feature can be added to an original XTB-ANR just by swapping the PIC.

Another Mouser order, another bunch of price increases:

DF04M bridge rectifier from .19 to .30 (100 qty)  up 58%
10 ohm 1W SMD resistor from .09 to .22 (10-99 qty)  up 144%
TL432 voltage reference from .17 to .23 (100 qty)  up 35%
MMBT2222A transistor from .05 to .09 (100 qty)  up 80%
PV37W103C01B00 trimpot from 1.74 to 2.10 (10-49 qty)  up 21%

Yes, it is pennies here and pennies there.  But with 50 or more components in a product, it adds up.

And of course there are the components back ordered until next summer or fall.

I've been buying components for almost 2 decades, and there have never been increases across the board like there have been over the last year.

Just checked availability of one of the PIC microcontrollers I use:

On Order:
5,948 Expected 2/13/2023
3,540 Expected 3/6/2023

No version of DIP or SMD was in stock at Mouser, Digikey, or any other distributor here in the US.  This may get worse with the supply of neon from the Ukraine being curtailed.

While I have sufficient inventory for now, component availability may cause the end of many products - not just mine.  Future firmware updates may require the existing chips to be re-programmed rather than providing new chips.
