387-042-524-804

Edgeboard Connectors Overview

The EDAC Inc. 387-042-524-804 is a standard card edge connector from the 387 series, designed for vertical through-hole mounting. It features 42 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, rated for 3 A current, and housed in black thermoplastic polyester. It supports PCB thicknesses of 1.37 mm to 1.78 mm (0.054" to 0.070") and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board insertion
• Vertical orientation with flanges for panel or chassis stability
• Gold-plated contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides thermal resistance

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces
• Medical device circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific position count and row configuration against the official datasheet before procurement, as the 387 series includes variants with different pin counts and termination types. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical fit. Check RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, vertical card edge interface is required for high-density applications. The 3.96 mm pitch allows for compact layout while maintaining adequate spacing. Ensure the application environment stays within the -40°C to +105°C operating range. Consider the gold plating for corrosion resistance in demanding environments compared to tin-plated alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 series of standard card edge connectors. The series is characterized by its 0.156 inch (3.96 mm) contact pitch and robust construction suitable for various industrial and commercial applications. The 387 series offers multiple configurations in terms of position count, row arrangement, and termination style to accommodate diverse design requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and form factor but different position counts, such as 387-020-520-804 or 387-034-524-103. Verify that any replacement matches the 42-position requirement and dual-row specification. Cross-series replacements require careful evaluation of pitch, height, and electrical ratings.
