Narrative:
On mar/wed/04, I replaced the #3 brake on a B737-800. I installed brake part number XXXX, which is a B737-700 brake. The correct part number for a B737-800 is YYYY. I released the aircraft for service. On mar/thu/04, I was informed that the error had been discovered by an auditor. I'm told the brake will be replaced tonight in ZZZ1. When the brake was delivered to my aircraft, I failed to verify the correct part number using the parts tag. The containers have markings on them to indicate 'B737-700,' for exchange. This does not guarantee that the brake you need is in the container marked for the series of aircraft you expect. This is where I went wrong. I will never again assume that a brake is in the container with a label that states the series of aircraft I expect to see. The parts tag and data plate are the only ways to be sure.
