387-042-521-202

Edgeboard Connectors Overview

The EDAC Inc. part number 387-042-521-202 is a standard card edge connector designed for single-sided board applications. It features 42 positions with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes female contacts with gold plating and a cantilever contact type, housed in a black thermoplastic polyester insulator. It supports through-hole termination and accommodates card thicknesses ranging from 0.054 to 0.070 inches. The unit operates within a temperature range of -40°C to 105°C and includes flange features for flush mounting with side openings.

Edgeboard Connectors Feature Summary

• Single-sided female connector configuration with cantilever contact design
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation housing with black coloration
• Through-hole termination method for secure PCB mounting

Edgeboard Connectors Applications

• Single-sided circuit board interconnection
• Industrial control system backplanes
• Telecommunications equipment interfaces
• General-purpose electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 337/387 Series Ordering Guide to ensure correct flange and termination specifications. Confirm that the target application requires a single-sided connector rather than a dual-sided variant. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the printed circuit board thickness falls within the specified 0.054 to 0.070 inch range for proper mating.

Edgeboard Connectors Selection Notes

Select this component when a single-sided interface with 42 positions is required. The 0.156-inch pitch is suitable for general-purpose high-density applications. Consider the cantilever contact type for ease of insertion and removal during maintenance. Verify that the through-hole mounting style aligns with the manufacturing process. Compare against dual-sided alternatives if both sides of the card require connection.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 series of standard card edge connectors. The series offers various position counts and configurations for different board types. The 387 series is widely used in industrial and commercial electronics for reliable board-to-board or board-to-backplane connections. Similar parts in the series differ primarily in position count and flange characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 387 series parts with identical 42-position single-sided specifications. Verify compatibility with existing PCB footprints and mounting hole patterns. Cross-reference with distributor databases for equivalent components from other manufacturers offering matching electrical and mechanical parameters.
