In a low-vibration bench or test fixture, that is fine. In a mobile or high-shock assembly, pair it with a locking receptacle or add a secondary retention method.
No official pin-compatible replacement or successor is listed. If you need a shrouded or locking version, the BERGSTIK II series offers similar pitch and pin counts with a shroud — but that is a different footprint and requires a board layout change.
The unshrouded header accepts both IDC ribbon-cable sockets and discrete crimp housings with the same pitch and row spacing.
