3M 3000 Series Straight Through Hole PCB Header, 64 Contacts, 2.54 mm Pitch, 2 Row, Shrouded N3764-6303RB

3M N3764-6303RB is a PCB header from the trusted 3000 Series, designed for straight through hole mounting with 64 male contacts arranged in 2 rows and a 2.54 mm pitch. Manufactured with glass filled polyester, it supports high temperature processes up to 260°C, making it ideal for lead-free soldering in compliance with JEDEC J-STD-020C standards.

The header features a shrouded housing providing 4 wall contact protection and includes roll pin style ejector latches that secure the connector while allowing easy removal even in high vibration conditions. The ejector latches improve retention and prevent damage during disconnection.

Contacts are made of copper alloy with gold plating to ensure low electrical resistance and durability. The connector system supports both board-to-board and wire-to-board mounting, making it versatile for a wide range of electronic assemblies.

This PCB header is rated for a maximum voltage of 25V and a current of 5.0A, operating reliably from -55°C to 105°C, which suits industrial, instrumentation, medical, communications, and data applications. The design includes center bump polarization and extra polarization slots to minimize misalignment during mating. Military polarization is achievable with the optional polarizing key (3M part number N3518).

Installation is secure with mounting holes and the connector layout aligns with standard PCB design specifications. Multiple versions exist with different latch styles and housing materials; this particular model has a high temperature PCT housing for enhanced thermal endurance.

These connectors are widely used in industrial and electronic component manufacturing, providing a robust, reliable interface where durable connections are critical. 3M’s 3000 Series PCB Headers are recognized for quality and performance in demanding environments.

Features a straight through hole mount type for board-to-board and wire-to-board connector systems. Housings are made of glass filled polyester allowing high temperature resistance up to 260°C for lead-free soldering. Includes 64 male copper alloy contacts plated with gold for reliable electrical connection and corrosion resistance.

Designed with 4 wall shrouding and ejector latches for secure mating and easy ejection in high vibration environments. Operating voltage up to 25V and current capacity of 5.0A suitable for various industrial and electronic applications.
