Single-Row Panel-Mount Housing for 10.16 mm Pitch Power Circuits
The TE 1-1747821-3 is a 3-position, single-row receptacle housing from the Dynamic D-5300 series, designed for panel-mount wire-to-wire or wire-to-board power interconnects where the 10.16 mm pitch gives generous creepage for higher-voltage runs without crowding the panel cutout. 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.
