3431-1202 Description

Short technical summary and product information.

The 3M 3431-1202 is a 34-position male pin header designed for board-to-board or cable-to-board applications. It features a 2.54mm pitch and is arranged in a 2-row configuration with all positions loaded. The connector is through-hole mounted with a right-angle orientation, making it suitable for compact layouts where space is limited.

 

The header is shrouded with a 3-wall design and includes a latch lock/eject hook fastening system for secure mating. Additional features include a keying slot and mounting flange for polarization and mechanical retention. The contacts are made of copper alloy with a tin-lead finish and a square shape, with a contact length of 2.84mm. The insulation is black, glass-filled PCT/polyester with a UL94 V-0 flammability rating.

 

Electrically, the connector is rated for 1.75A per contact, and it operates over a temperature range of -55°C to 105°C. The row spacing is also 2.54mm, ensuring consistent alignment with standard mating headers.
