837-031-558-108

Edgeboard Connectors Overview

The EDAC Inc. 837-031-558-108 is a single-row female card edge connector designed for through-hole mounting. It features 31 positions with a 0.156-inch (3.96mm) contact spacing. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The insulator is constructed from green diallyl phthalate (DAP), supporting an operating temperature range of -40°C to 125°C. It accommodates card thicknesses between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Utilizes cantilever spring contacts for reliable board insertion
• Features a flange with top opening and threaded inserts for secure panel mounting
• Constructed with high-temperature DAP insulator material

Edgeboard Connectors Applications

• High-temperature industrial control systems
• Automotive electronics modules
• Communication equipment backplanes
• Military and aerospace circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct termination style and flange configuration. Confirm that the required card thickness falls within the specified tolerance range. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure the mounting hole pattern matches the threaded insert specifications provided in the mechanical drawings.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-contact-count interface is required for thick PCBs. The 0.156-inch pitch suits applications where standard density is not critical but robust mechanical retention is needed. Consider the through-hole wire-wrap or solder termination options available within the series based on manufacturing capabilities. Evaluate the need for the specific flange mounting style versus other series variants.

Edgeboard Connectors Part Context

This part belongs to the EDAC 837 High Temperature Series, characterized by durable materials suitable for harsh environments. The series offers various position counts and termination styles. The 837-031 variant specifically addresses needs for higher density interconnects in a single row format while maintaining the structural integrity expected in industrial-grade connectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 837 series models with matching pin counts and pitch. Verify compatibility with existing panel cutouts due to the specific flange design. Cross-reference with 337 series parts if different termination methods are acceptable, ensuring electrical and mechanical parameters align.
