305-076-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-076-555-503 is a standard card edge connector header featuring 76 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts and solder lug termination for secure mounting. Designed for panel installation, it operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 76 connection points
• Gold-plated copper alloy contacts for reliable conductivity
• Solder lug termination style for panel mounting
• Compatible with 1.57 mm nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify the specific contact code suffix against official EDAC documentation to confirm tail length and bend specifications. Ensure the ordering part number matches the required row count and position quantity. Confirm compliance with RoHS directives if restricted materials are prohibited in your assembly process. Cross-reference the datasheet for precise dimensional tolerances before integration.

Edgeboard Connectors Selection Notes

Select this model when a high-density dual-row interface is required for thick PCBs. The 3.96 mm pitch suits applications where board alignment precision is moderate. Verify that the 5 A current rating meets the electrical load requirements. Consider the vertical panel mount style for chassis-based designs requiring robust mechanical retention.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and termination styles to accommodate different board thicknesses and mounting configurations. The 305 line is engineered for durability in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 76-position dual-row layouts and 3.96 mm pitch. Verify that alternative part numbers maintain the same 1.57 mm board thickness compatibility and gold plating specifications to ensure functional interchangeability.
