Direct replacement for 16F688

[Christopher4187]

I am selling a device where I use a 16F688. I originally thought I needed the 688 but after selling a few hundred units, the customer never wanted that option implemented and he never will. I can purchase a 16F688 for $1.28 and a 16F505 for $1.05. It is a matter of saving money.

How many do you plan to sell? If you make the change and sell a “few hundred “ more, you will save $69 – a thousand more, you will save $230. Is it worth changing and retesting a perfectly good working product for that kind of money (and risk that they might not work the same)? Consider leaving it as is and working on your “next” money maker instead. Or, if the money out of your pocket is an issue, why not charge $.25 more for the product and come out ahead. If that is not an option, you could split the difference with your customers and charge $.12 more. I know what I would do.

Paul,

I thought about the same thing a while ago but it's better to have the mentality of saving money rather than spending it. I was thinking about changing a few other items on the board with the hopes of saving a few dollars for each unit. It was just a thought I was throwing around but maybe I was trying to pinch too many pennies.

you could also compare the C serie against F serie.

EDIT: i thought it was usually cheaper.. seems not at digikey today. Maybe different from a supplier to another.
