Backshell That Completes the D-Sub Assembly
The TE Connectivity 5748677-2 is a two-piece backshell from the AMPLIMITE HD-20 series, designed to terminate and shield a 15-position D-sub connector. It accepts round cable with a 180° straight exit, making it a straightforward choice for inline cable runs where the cable leaves the connector in the same axis as the mating direction. The shielded construction — nickel over copper plating on the ABS shell — provides a continuous ground path around the connector interface, which matters when the assembly sits near switching supplies or data lines.
Hardware Included — No Separate Screw Order
This backshell ships with mating screws (4-40 thread) and assembly hardware including grommets. The 4-40 screws are the standard thread for D-sub backshell retention — they engage the threaded inserts on the mating D-sub connector. Having them in the pack means one less line item on the BOM. The grommets provide strain relief at the cable entry point, clamping the round cable jacket to prevent pull-out from the solder bucket or crimp termination inside.
Shell Size and Compatibility — One Backshell, Two Connector Sizes
The 5748677-2 is listed as compatible with D-sub shell size A, which covers both standard 15-position and high-density 26-position connectors. That means a single backshell SKU can serve two different connector builds — useful for consolidating inventory if your harness shop runs both standard and HD D-subs. The 15-position count on the backshell matches the standard 15-pin D-sub footprint; the same shell also fits the HD-26 variant because the outer shell dimensions are identical between those two sizes in the AMPLIMITE HD-20 family.
Cross-Shop Note — 7-1437064-0 as a Functional Peer
The 7-1437064-0 is another AMPLIMITE HD-20 backshell in the same series, same shell size A, same 15-position fit. The difference is packaging: the 5748677-2 ships in bulk, while the 7-1437064-0 comes in a tube. Both are active and ROHS3 compliant. If your pick-and-place or kitting line prefers tube feed for the backshell hardware, the 7-1437064-0 is the tube-packaged alternative; otherwise the bulk-pack 5748677-2 covers the same assembly job.
