The TE Connectivity 787003-3 is a CHAMP series locking post — a board-mount accessory, not a connector. It secures the mating halves of CHAMP D-Sub connectors by threading into the connector's jack-screw holes with its M2 thread, then passing through the PCB to anchor the assembly. The 6.00 mm length below the head gives clearance for standard board thicknesses and panel stacks. Bulk packaged for hand assembly or kitting.
M2 Thread and Fit
The M2 thread size matches the standard jack-screw thread on CHAMP D-Sub connector housings. This post replaces or supplements the original screw-lock hardware — it threads into the same M2-tapped hole in the connector body, then the 6.00 mm shank passes through the board and is secured with a nut or the board's own plated hole. The thread is the fit-critical dimension: an M2.5 or #4-40 post will not engage.
Compatibility — Which Connectors It Works With
The 787003-3 is listed for use with CHAMP D-Sub connectors — the full family of TE's CHAMP D-Sub housings that carry the M2 jack-screw thread. This includes standard-density and high-density CHAMP D-Subs across all position counts. It does not fit standard D-Sub connectors (which use 4-40 or M3 thread) or other connector families. If the connector body says CHAMP and has M2 threaded inserts, this post is the correct locking hardware.
