What it does not have
The 75844-222-72LF: The header is unshrouded and uses a push-pull breakaway fastening type — there is no polarizing key, polarizing rib, or polarized slot to prevent mis-mating in a dense connector field. If your application needs mate-keying or polarized alignment, look to a shrouded BERGSTIK variant or a different series with built-in keying. The 72 positions are all loaded; there are no stripped or partial-load positions in this part number. Row spacing matches the 0.100" (2.54mm) pitch, so the two rows sit 2.54mm apart — standard grid, which mates with any 0.100" dual-row IDC or crimp receptacle that accepts a 0.100" pitch header.
Where this connector lives
Board-to-board stacking, board-to-cable harness takeoff, and test-fixture patch are the typical uses for a 72-position breakaway header at this pitch. The 72-circuit count is large enough to carry a parallel bus or multi-signal harness bundle but compact enough that the 0.100" pitch still fits standard 2.54mm grid routed boards. The 130°C upper temperature limit covers reflow-profiled assembly and industrial environments that run hot; the -65°C lower limit covers cold-start and outdoor enclosures. UL94 V-0 housing material means it clears the most common flame-retardancy requirement for industrial control panels and instrumentation.
