Product details

28-Position Dual-Row Footprint — 0.100" Pitch

The through-hole solder tails extend 0.140" (3.56 mm) below the insulator — enough for a standard 0.062" PCB with room for the solder fillet.

Tin-Plated Contacts — 100.0 µin Mating Surface

Post finish is 30.0 µin tin, standard for solder joint reliability.

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.

Frequently asked questions

What is the mating connector for 65781-050?

The specific mating part number depends on your board-to-board stack height and pin length; look for a Dubox or compatible 28-position header with matching pitch and row spacing.

What is the insulation height of 65781-050?

The insulation height is 0.335" (8.51 mm). This dimension, combined with the mating header's height, determines the total board-to-board stack height.
