387-020-520-808

Edgeboard Connectors Overview

The EDAC Inc. 387-020-520-808 is a standard card edge connector designed for vertical through-hole mounting. It features a dual-edge female configuration with 20 positions and a 0.156-inch (3.96 mm) contact spacing. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. It is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The housing is constructed from thermoplastic polyester, providing structural integrity and electrical insulation.

Edgeboard Connectors Feature Summary

• Dual-edge female receptacle design for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Vertical through-hole termination for PCB integration
• Thermoplastic polyester insulator body for durability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Computer peripheral interface modules
• Test and measurement instrumentation cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 387 Series Ordering Guide to confirm flange type and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status if required by project regulations. Cross-reference the DigiKey part number 151-387-020-520-808 for accurate distributor identification and availability checks.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector is required for vertical mounting applications. The 0.156-inch pitch suits standard industrial board layouts. Verify that the target PCB thickness aligns with the 0.062-inch specification. Consider the high-profile insulator body dimensions for enclosure clearance requirements. Ensure the gold plating meets the environmental conditions of the deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 Series, which provides standard card edge connectors with 0.156-inch spacing. The series offers various position counts and termination styles. The 387-020-520-808 specifically addresses dual-edge applications, distinguishing it from single-edge variants within the same family. It shares common material properties and thermal ratings with other models in the 387 lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 387 series include 387-020-520-804 and 387-020-520-604, provided the flange configurations match the mechanical design. Verify that alternative parts maintain the same 20-position count and dual-edge female characteristics. Ensure any replacement maintains the 0.156-inch pitch and compatible PCB thickness tolerance.
