The broken latch has "C-7442-5" molded on its' underside. The door handle screws are 2.5" measured center to center. Hope you can identify the replacement part based on these photos and description.

Thanks for posting, Ralph. Check out our 82-043 in the color white. You may also want consider purchasing a new internal mortise lock. See part 82-037, which is a mortise lock for a 2 panel Andersen sliding door. Make sure to match up your existing mortise lock with the dimensions found on the 82-037 product page.
