3428-6303 Description

Short technical summary and product information.

The 3M 3428-6303 is a 20-position, 2-row shrouded header with male pins on a 2.54mm (0.100") pitch. It features a through hole termination with solder contacts. The contacts are made of copper alloy with a tin-lead finish (30µin thickness). The insulation is black PBT/polyester with glass fill, rated UL94 V-0. The header includes a 4-wall shrouding, latch lock/eject hooks, keying slot, and mounting flange for secure board-to-board or cable connections.

 

With a current rating of 1A and an operating temperature range of -55°C to 105°C, this connector is suitable for industrial and commercial applications. The overall contact length is 17.65mm, and the insulation height is 17.27mm. Row spacing and pitch are both 2.54mm, providing a standard 0.100" grid. The contact length (mating length) is 3.94mm.

 

This header is designed for board-to-board or cable-to-board interfacing where a keyed and locked connection is required. The mounting flange and latch lock ensure mechanical stability. The shrouded design protects pins and provides polarization. All 20 positions are loaded.
