316-039-521-103

Edgeboard Connectors Overview

The EDAC Inc. part number 316-039-521-103 is a card edge connector from the 316 series, designed for through-hole mounting. It features a dual female contact configuration with 78 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and accommodates a board thickness of 1.57 mm. The contacts are gold-plated copper alloy, providing reliable electrical performance. This component is classified as a standard card edge connector suitable for vertical installation.

Edgeboard Connectors Feature Summary

• Dual female contact design for secure card edge engagement
• Gold-plated copper alloy contacts for enhanced conductivity
• Through-hole termination method for stable PCB integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• General-purpose electronic assemblies needing high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required board thickness and contact plating specifications. Confirm that the dual female configuration aligns with the mating card edge requirements. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the through-hole mounting style matches the target printed circuit board layout constraints.

Edgeboard Connectors Selection Notes

Select this connector when a dual-sided card edge interface is required for signal integrity. The 0.156-inch pitch allows for higher density compared to larger spacing options. Verify that the 1.57 mm board thickness specification matches the design parameters. Consider the vertical orientation for space-constrained enclosures where horizontal clearance is limited.

Edgeboard Connectors Part Context

This component belongs to the EDAC 316 series of card edge connectors, which are engineered for high-reliability applications. The series offers various position counts and mounting styles to support diverse electronic design needs. The 316-039-521-103 variant specifically addresses requirements for dual-row connectivity with standard through-hole assembly processes.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting or plating options. Cross-series replacements require verification of mechanical dimensions and electrical ratings. Ensure any alternative maintains the dual female contact type and compatible board thickness tolerance.
