D-Sub Backshell for 25-Position Shell Size B
The TE Connectivity 2-2198617-5 is a two-piece plastic backshell from the ADK series, designed to fit standard 25-position D-sub connectors with Shell Size B. The ABS housing includes the assembly hardware — 4-40 mating screws, grommets, and strain relief — so the backshell arrives ready to install without sourcing separate fasteners.
25 vs 37 Positions — Same Shell Size, Different Cable Bundle
The same ADK series includes a 37-position variant, 3-2198617-7, that shares the Shell Size B footprint. The 25-position 2-2198617-5 fits the standard DB-25 cable bundle; the 37-position sibling takes a larger round cable for the extra conductors. Both use the same 4-40 screw hardware and shielded construction — the choice is driven by the D-sub pin count on the harness.
