The Amphenol Delta D D3W3P36A6GX08LF is a D-Sub combo plug carrying 3 power contacts in a single row, laid out on the 2 (DA, A) - 3W3 shell size. It is a right-angle through-hole male connector with gold-plated pins — 30.0µin on the mating interface — rated 30 A per contact at 300 V. This is a power-blend D-Sub: the three contacts carry bus-level current while the shell footprint matches a standard DA-size panel cutout. It is used where a signal-density D-Sub would be undersized for the power rail — power supply outputs, industrial drive interconnects, battery management harnesses, and server PSU boards that need a single connector for both signal and power.
What the 30 A Rating Means for the Build
30 A per contact is the rated current for each power pin. The brass contact material with that plating grade resists fretting corrosion better than a tin finish when the connector sees thermal cycling or vibration.
Right-angle through-hole termination with board lock and grounding indents. The backset spacing is 0.374" (9.50 mm) — this sets the distance from the PCB edge to the mounting flange, so the panel cutout location relative to the board edge must match this dimension. The flange feature is Housing/Shell (4-40), meaning the plug uses 4-40 threaded inserts for jack-screw retention.
The D3W3P36A6GX08LF shares the same 3 (Power) position count, 30 A rating, 300 V, gold 30.0µin plating, board lock, grounding indents, and right-angle through-hole mounting with the D3W3P36A6GL08LF and D3W3P36A6GV08LF. The difference is the flange feature: the GX uses Housing/Shell (4-40) threaded inserts; the GL uses Housing/Shell (M3); the GV adds Mating Side, Female Screwlock (4-40) plus mounting brackets. If your panel or mating receptacle is tooled for 4-40 jack-screws, the GX is the direct fit — the GL with M3 would require a different screw. The GV's extra mounting brackets add mechanical stability but change the panel cutout clearance.
