What the ratings mean for the fit
The 431605302: The Board Lock feature provides positive mechanical retention during solder reflow and resists shear forces from cable strain after assembly. The Locking Ramp fastening type gives an audible click when the mating receptacle is fully seated, which is useful in high-vibration environments where a friction-only connector would walk loose over time.
