The Amphenol FCI DB25P564CTXLF is a 25-position D-sub plug (male pins) in the standard DB-25 shell size — layout 3 (DB, B).
Right-angle through-hole mounting means the solder tails exit the bottom of the insulator and bend 90 degrees to align with the PCB holes. The backset spacing is 0.409" (10.40 mm) — the distance from the mounting face to the first row of pins — which sets the board-edge clearance. The flange feature is housing/shell (unthreaded), so the connector uses the standard D-sub footprint with 4-40 threaded inserts on the mating half or backshell, not on the plug itself.
How It Compares: DB25P564GTXLF
The difference is packaging and features: the DB25P564CTXLF ships in tray and includes grounding indents; the DB25P564GTXLF ships in bulk and adds board locks for extra PCB retention during wave solder. If your assembly needs the mechanical anchor of board locks, the GTXLF variant is the one to specify. Otherwise, the CTXLF covers the same signal path at the same footprint.
