I guess that I am one of those who gets her panties in a wad. (so uncomfortable LOL) But the DBX1 is not the same as a 15x1. The 15x1 is a flat shank and the DBX1 is a round shank. However, the timing length (top of shank to top of the eye) is the same. And most later model machines that take a flat shank will not take a round shank.
The real difference is the length after the point. If a DBX1 needle will fit in the 206 the point may hit the bobbincase, it depends on the whether or not the bobbincase is the open style or not. But one also needs to consider that the longer point may not clear the fabric at the point that the feeddogs start moving or hit the fabric while the feeddog are still moving.This can be a problem with thicker fabrics. One might not think that the slight point difference is a problem, but if you have timed a machine you know that very tiny differences can have a big impact.
Here is a picture that shows the point differences. Note that the DBX1 from different manufacturers will have different length tips.

So, stick with the original needles, they are available in a number of places.
