In a telecom or industrial card that gets swapped quarterly, that's a decade-plus of field service at the interface. The housing is glass-filled thermoplastic, rated UL94 V-0, and coloured blue for visual identification in a dense backplane. The push-pull fastening means it seats and unseats without tools — handy for field-swappable cards where you don't want a latch mechanism to snag.

The 24-position 71991-312LF is the nearest second-source within the same Dubox™ series — same pitch, stack height, plating, and housing. The 20-position 71991-310LF is also a direct sibling.
