The black colour is standard across the D-5300 series and carries no functional difference from the grey variants in the broader Dynamic family. ## 3 vs 4 Positions — Single-Row Panel-Mount Decision The 1-1747821-3 carries 3 positions in a single row. The nearest same-series sibling is the 1-1747822-2, a 4-position, dual-row receptacle housing at the same 10.16 mm pitch and panel-mount footprint. The dual-row body adds a mounting flange and a second row of cavities, which changes the panel cutout width and the crimp-terminal count per harness. For a 3-wire circuit the single-row housing is the direct fit; the 4-position dual-row is a different panel layout and a different terminal count. No official cross-reference from Molex or other brands exists in the manufacturer documentation; the Dynamic D-5300 series is TE Connectivity proprietary tooling. The plug uses tab contacts and is free-hanging (in-line), so the mated pair forms a panel-mount receptacle to in-line plug connection. The crimp terminals for both halves are ordered separately — the receptacle uses female socket contacts, the plug uses tab contacts.","metaTitle":"TE 1-1747821-3 Dynamic D-5300 Receptacle Housing, 3 Pos","metaDescription":"TE 1-1747821-3 Dynamic D-5300 3-position single-row receptacle housing, 10.16 mm pitch, panel mount, crimp termination.
