The BergStik series is widely second-sourced; if you need a direct drop-in, the 0.100" pitch and 50-position count are the key matching criteria.
The key matching parameters are the 50 positions, 2 rows, 2.54mm pitch, and through-hole termination. No official direct replacement is listed by Amphenol ICC.
