857-035-557-108

Edgeboard Connectors Overview

The EDAC Inc. 857-035-557-108 is a standard card edge connector receptacle designed for high-reliability applications. It features 70 positions with a 3.96 mm pitch, accommodating a board thickness of 3.96 mm (0.156 inches). The component utilizes gold-plated copper alloy contacts and a polyphenylene sulfide housing to ensure durability in demanding environments. Rated for 5 A current, it supports wire wrap termination and panel mount installation at a vertical angle.

• Gold-plated copper alloy contacts for corrosion resistance
• Polyphenylene sulfide housing material for thermal stability

Edgeboard Connectors Applications

• Industrial control systems
• Power supply units
• Storage devices

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version for the 857-035-557-108 model to confirm exact insulation resistance and operating temperature ranges, as these parameters can vary by manufacturing batch. Ensure compatibility with the target PCB thickness of 0.156 inches before procurement. Cross-reference the pin count and termination style with system requirements to prevent integration errors during assembly.

Edgeboard Connectors Selection Notes

Select this connector when a 70-position dual-edge interface is required for panel-mounted applications. The 3.96 mm pitch dictates the associated PCB trace layout. Consider the vertical mounting orientation and wire wrap termination method during mechanical design. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors. The series is characterized by robust construction suitable for industrial and commercial electronics. Similar models in the series vary primarily in position count and housing material, offering scalable solutions for different density requirements within the same form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 857 series variants with matching 70 positions and 3.96 mm pitch. Ensure replacement parts maintain the same gold plating and PPS housing specifications to preserve environmental performance and electrical continuity.
