Where do I find female headers with pins just long enough (~6mm) to fit a breadboard?
Ordinary socket headers such as these:
have pins that are too short to stay put in the breadboard, but the so-called stacking headers such as these:
have pins that are too long and too thin.
I sometimes have breakout boards with parts underneath (they are meant to be plugged into another board with socket headers), which I want to be able to use on the breadboard. The male-female extension wires from Adafruit are great for momentary checks, but not for something that might last a few weeks on the breadboard.
I can't find anything on Mouser, and even since Digikey stopped having a printed/PDF catalog, it's impossible to find anything unless you know the exact part number.
I know I can get the stacking headers and trim them, but there has to be a tidier solution.
