96-Position DIN 41612 Plug, Right-Angle, 64 Contacts Loaded
The 650945-5: It is a Style C connector — the shell carries all 96 position cavities, but only 64 contacts are loaded, leaving the remaining positions as empty slots for optional future expansion or custom pin-out patterns. The 3-row, 96-position footprint follows the standard DIN 41612 Type C layout, so the PCB pad pattern is well-documented and shared across multiple vendors' compatible receptacles.
What the 64 Loaded Positions Mean for the Fit
The 650945-5 carries 96 position cavities but only 64 contacts are loaded. This is the typical configuration for a Eurocard connector where the backplane receptacle has all 96 positions, but the daughtercard only needs 64 signal lines. The empty cavities are simply unpopulated — the plastic shell still provides the full keying and alignment. When replacing a failed connector on a board, confirm that the original part was also a 64-loaded variant and that the pin-out pattern matches the circuit assignments on the PCB. A fully loaded 96-position plug (like the 650945-1) would fit the same footprint but requires all 96 through-holes to be populated.
