305-076-556-501

Edgeboard Connectors Overview

The EDAC Inc. model 305-076-556-501 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features 76 positions with a dual female contact configuration and a pitch of 3.96 mm (0.156 inches). The contacts are gold-plated copper alloy, suitable for reliable signal transmission. The housing is constructed from green thermoplastic material, supporting a maximum operating temperature of +105°C and a minimum of -40°C. This component utilizes solder pin termination for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for robust card edge interface
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Vertical panel mount style facilitates structured enclosure integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact plating thickness and insulation resistance ratings. Ensure compatibility with the target PCB slot dimensions and verify that the panel mounting requirements align with the mechanical constraints of the final assembly design before procurement.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 76-position interface is required within a vertical panel-mount architecture. The 3.96 mm pitch accommodates standard double-sided PCBs. Consider the thermal range and gold plating if the environment demands high reliability or exposure to corrosive agents compared to tin-plated alternatives.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles, providing modular solutions for board-to-board and board-to-backplane applications. The 305 series is characterized by its durable thermoplastic housing and standardized mechanical footprint.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants such as 305-076-556-201, provided the termination style matches the assembly requirements. Cross-reference mechanical drawings to ensure identical panel cutout dimensions and mating height specifications.
