The friction lock fastening provides a positive hold against vibration without a secondary latch — enough retention for a cable harness inside an enclosure that sees occasional movement, but not rated for high-shock environments where a TPA or screw-lock would be specified.
At 26 positions loaded across two rows, this header fills a mid-density I/O slot on a PCB.
How it compares to similar AMPMODU Mod II headers
Compared to the 6-position 953440-3 and the 12-position 1379030-3, the 827881-2 carries 26 positions — a higher density for a wider I/O count. The 1394090-1 is a single-row, 6-position header with a different pitch (0.112") and latch holder — not a direct alternative for a 26-position dual-row application.
