357-031-405-178

Edgeboard Connectors Overview

The EDAC Inc. 357-031-405-178 is a standard card edge connector from the 357 series, designed for single-edge board applications. It features 31 positions with a pitch of 0.156 inches (3.96 mm). The connector utilizes female contacts with tin plating and is constructed from black thermoplastic polyester insulation. It supports a PCB thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Single-edge female connector configuration for reliable signal transmission
• Thermoplastic polyester insulation provides durable structural integrity
• Tin-plated contacts ensure effective conductivity in standard environments

Edgeboard Connectors Applications

• General electronic circuit board interconnections
• Industrial control system modules
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific contact plating specification against the official manufacturer datasheet, as distributor listings may vary between tin and gold finishes for this part number. Confirm that the required PCB thickness falls within the 0.054 to 0.070 inch range to ensure proper mechanical engagement. Check RoHS compliance details directly with the supplier documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row, vertical mount card edge interface is required for boards up to 0.070 inches thick. The 31-position count suits moderate-density applications. Ensure the operating environment remains within the specified -40°C to +105°C thermal limits. Tin plating is suitable for general use but may require consideration if high corrosion resistance or low contact resistance is critical compared to gold alternatives.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 357 series, which offers a comprehensive range of card edge solutions. The series is characterized by its standardized 0.156-inch pitch and robust thermoplastic housing. This specific model represents a mid-range position count option within the family, balancing connectivity density with physical footprint constraints for various industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 357 series variants with matching 31 positions and 3.96 mm pitch, such as 357-031-527-104, provided contact plating and PCB thickness tolerances align with design requirements.
