387-031-542-602

Edgeboard Connectors Overview

The EDAC Inc. 387-031-542-602 is a single-row card edge connector designed for vertical through-hole mounting. It features 31 positions with a 0.156-inch (3.96 mm) contact spacing and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes copper alloy cantilever contacts with a gold plating finish to ensure reliable signal transmission. Insulation is provided by black thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C. This component includes top mount openings with unthreaded flanges measuring 0.128 inches in diameter for secure panel installation.

Edgeboard Connectors Feature Summary

• Thermoplastic polyester insulation rated for high temperatures
• Vertical through-hole termination for PCB integration

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Embedded computing module slot interfaces
• Test and measurement instrument card slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 387 Series Ordering Guide to confirm exact pin count, termination style, and flange specifications. Ensure compatibility with target PCB stack-up dimensions and verify RoHS compliance status prior to procurement. Cross-reference the DigiKey or Mouser part number alias to confirm supply chain availability and lead times.

Edgeboard Connectors Selection Notes

Select this connector when a single-row, 31-position interface is required for vertical board insertion. Confirm that the host PCB thickness falls within the specified 0.054 to 0.070 inch range. Evaluate thermal requirements against the -40°C to +105°C operational limit. Consider the unthreaded flange design for applications requiring simple panel mounting without threaded fasteners.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 Series of standard card edge connectors. The series offers various configurations including different row counts, termination types, and flange options. The 387-031-542-602 specifically represents a 31-position variant with gold plating and thermoplastic insulation, designed for robust industrial and commercial electronic applications requiring reliable edge-board connectivity.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 387 Series Ordering Guide for direct substitutes with identical electrical and mechanical parameters. Verify alternative part numbers from other manufacturers only if they match the 0.156-inch pitch, 31-position count, and vertical through-hole mounting style.
