The TE Connectivity 1658683-1 is a 44-position, 3-row receptacle housing from the AMPLIMITE HDP-22 series, configured as a high-density D-sub (shell size 3 / DB / B layout). It accepts female crimp contacts and mounts free-hanging (in-line) for cable-to-panel or cable-to-cable harness assemblies. The shell is steel with tin plating at 200 µ in (5.08 µm) thickness, providing EMI shielding and corrosion resistance for industrial control cabinets, test equipment, and data-communications racks where a high-density pin count is needed in a standard D-sub footprint. The housing is black glass-filled polyamide (PA / Nylon), rated UL94 V-0 for equipment inside enclosures requiring flame-rated materials.
44 Circuits in a DB-Shell Footprint — High-Density Layout
The high-density layout packs 44 signal contacts into a shell size 3 (DB, B) footprint — the same shell that carries 25 positions in a standard-density D-sub. The 3-row staggered arrangement reduces the per-contact pitch compared to a 2-row layout, which means the mating plug and crimp contacts must be the AMPLIMITE HDP-22 high-density type, not standard D-sub hardware. The 44-position count matches the circuit count on a BOM line for a high-density D-sub harness — confirm the mating plug is also a 44-position AMPLIMITE HDP-22 high-density shell.
Mating and Termination — Cable-Harness Assembly
This receptacle housing mates with a 44-position AMPLIMITE HDP-22 high-density D-sub plug (male pin housing) of the same shell size 3 / DB / B layout. The 3-row contact arrangement requires a sequential insertion tool that supports the high-density staggered pattern; the crimp contacts must be fully seated until the retention tang locks into the housing cavity.
