307-076-400-258

Edgeboard Connectors Overview

The EDAC Inc. 307-076-400-258 is a standard card edge connector receptacle featuring 76 positions arranged in a dual-row configuration. It utilizes a contact spacing of 3.96 mm (0.156 inches) with a row spacing of 5.08 mm (0.200 inches). The component is designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It employs gold-plated copper alloy contacts and a thermoplastic polyester insulator body, supporting panel mount installation.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure board insertion
• Low profile insulator body construction
• Gold-plated copper alloy contacts for conductivity
• Thermoplastic polyester housing material

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with 1.57mm PCB thickness and 3.96mm pitch requirements. Ensure that the selected variant matches the required mounting style and termination type for the intended assembly process. Cross-reference datasheet specifications for environmental ratings and current carrying capacity before integration into final designs.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required for panels or chassis mounting. The 76-position count suits applications needing high-density signal routing within a constrained vertical footprint. Consider the 3.96mm pitch and 1.57mm board thickness constraints during mechanical design. Verify that the thermoplastic polyester housing meets the thermal and chemical resistance needs of the operating environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 307 Series, which defines standard card edge connectors characterized by 3.96mm contact spacing and 5.08mm row spacing. The series is engineered for reliable mating with 1.57mm thick PCBs. The 307-076-400-258 specifically denotes a 76-position receptacle variant within this standardized family, ensuring interchangeability with other components sharing these dimensional parameters.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers within the 307 series that share identical positioning, pitch, and board thickness specifications, such as the 307-076-420-258 or 307-076-422-203, provided they match the required termination and mounting style.
