307-031-531-178

Edgeboard Connectors Overview

The EDAC Inc. 307-031-531-178 is a standard card edge connector header from the 307 series, designed for vertical panel mounting applications. It features 31 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 5.08 mm (0.200 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, while the insulator body is made of thermoplastic material.

Edgeboard Connectors Feature Summary

• Single row female card edge connector design with low profile insulator body
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount configuration for secure structural integration
• Compatible with 1.57 mm nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and contact orientation against your schematic before ordering. Confirm that the target PCB thickness matches the 1.57 mm specification to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure compatibility with existing panel cutouts and mounting hardware requirements.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-density connection is required for thick PCBs. The 3.96 mm pitch offers robust spacing compared to finer pitches. Consider the vertical mounting style if space constraints require perpendicular board insertion. Verify environmental ratings if operating in extreme temperatures beyond standard ranges.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 Series, which provides standardized card edge solutions. The series is characterized by consistent 3.96 mm contact spacing across various position counts. These connectors are engineered for durability in demanding electronic environments, offering a balance between mechanical stability and electrical performance for modular system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and board thickness but different pin counts, such as 307-030-531-178 or 307-035-531-178. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to maintain system integrity.
