305-018-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-018-555-503 is a standard card edge connector header featuring 18 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for .062 inch (1.57 mm) nominal thickness printed circuit boards. The component employs gold-plated copper alloy contacts with a half-bean spring type, rated for 5 A current. It supports panel mount installation at a vertical angle using solder lug termination. The insulating body is constructed from thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female header design for reliable board-to-board interconnection
• Gold-plated half-beam spring contacts ensure low resistance and durability
• Thermoplastic polyester housing provides thermal stability and insulation
• Panel mount vertical orientation with solder lug termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic sub-systems

Edgeboard Connectors Procurement Notes

Verify the specific flange feature configuration, as suffix variations indicate different mechanical mounting styles such as flush mount or floating bobbin designs. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required panel cutout dimensions and mounting hardware specifications for proper integration.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 3.96 mm pitch is required for .062 inch thick PCBs. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Evaluate the specific flange style needed for the enclosure, as mechanical mounting requirements dictate the appropriate suffix selection within the 305 series family.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors designed for high-reliability applications. The series offers various position counts and mounting configurations, all sharing a consistent 3.96 mm pitch and robust construction. The 305-018-555-503 specifically addresses needs for 18-position dual-row connections with specialized panel mounting features.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include variants like 305-018-555-507 or 305-018-555-508, which share identical electrical parameters but differ in plating or flange mechanics. Cross-brand replacements require matching the 3.96 mm pitch, 18-position count, and .062 inch board thickness constraints.
