333-078-560-203

Edgeboard Connectors Overview

The EDAC Inc. 333-078-560-203 is a standard card edge connector designed for through-hole mounting with a vertical orientation. It features 78 positions arranged in a dual-row configuration, providing a total of 78 contact points. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 inches to 0.070 inches (1.37 mm to 1.78 mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing is made of thermoplastic polyester, offering durability and an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified card applications
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Thermoplastic polyester housing provides structural integrity and thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board-to-board connections
• Computing hardware peripheral interface modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with target PCB stack-up dimensions, particularly the 1.37mm to 1.78mm thickness requirement. Confirm that the vertical through-hole mounting style aligns with the assembly process and mechanical constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for non-standard card geometries. The 3.96mm pitch allows for broader trace spacing compared to finer pitches, reducing manufacturing complexity. Verify that the 3A current rating meets the electrical load requirements of the application circuitry before finalizing the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 333 series of standard card edge connectors. The series is characterized by its versatility in handling various card types and its robust construction suitable for demanding environments. The 333 series typically offers a wide range of position counts and mounting options to accommodate diverse electronic packaging needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as the 333-070-560-203 or 333-080-560-203, provided the mechanical footprint and pinout requirements allow for adjustment.
