HI,
SN75LVDS83BZQLR bought DC 13+, comparing DC 21+, got difference on the X-ray and optical images but part QC testing passed.
regarding the change in the PCB substrate design. Additionally, please check the X-ray and optical images we've provided (attached) with them to confirm that the change does not have any adverse effects on the part's form, fit, or function. Thank you.
