The TE Connectivity 5745967-2 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, shell size 3 (DB, B). The polyester dielectric and steel shell with tin plating handle the mechanical and EMI-shielding role.
Flange Feature: Unthreaded Shell — Plan Your Screw-Lock Hardware
The 5745967-2 uses an unthreaded housing/shell flange. This is the same 25-position DB footprint as the 5745967-8, but the -8 adds 4-40 threaded inserts in the flange for captive jack-screws. If your assembly requires screw-lock retention — typical for cables that get plugged and unplugged in the field — the 5745967-8 saves a hardware step. If you are panel-mounting with separate standoffs or don't need threaded flanges, this part keeps the BOM simpler.
