No official second source or pin-compatible replacement is listed, so the 65781-050 is the direct line item for the 28-position Dubox receptacle. ## Housing and Compliance — UL94 V-0 The insulator is glass-filled polyester rated UL94 V-0 — the highest flame-retardant grade for connectors inside enclosed equipment.","metaTitle":"65781-050 Dubox 28-Pin 2.54mm Receptacle","metaDescription":"Dubox 28-position board-to-board receptacle, 0.100\" pitch, through-hole, tin-plated contacts, UL94 V-0.
