306-025-500-104

Overview

The EDAC Inc. 306-025-500-104 is a standard card edge connector designed for panel mounting applications. It features a dual-edge female configuration with 25 positions and a contact spacing of 0.156 inches (3.96mm). The connector utilizes gold-plated contacts on a copper alloy substrate, housed within a green thermoplastic insulator body. It is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component operates reliably within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Feature Summary

• Dual-edge female contact configuration ensures secure mating with specified PCB edge cards
• Gold-plated contacts provide durable electrical connectivity and corrosion resistance
• Low-profile insulator body facilitates compact panel-mounted installations
• Thermoplastic housing material supports operation across extended industrial temperature ranges

Applications

• Panel-mounted electronic interconnect systems requiring standardized card edge interfaces
• Industrial control modules utilizing 0.062-inch nominal thickness printed circuit boards
• Equipment assemblies demanding reliable dual-row signal transmission in constrained spaces

Procurement Notes

Verify that the target application requires a dual-edge female connector compatible with 0.062-inch thick PCBs. Confirm that the system design accommodates the 0.156-inch contact spacing and panel mounting requirements. Ensure environmental conditions remain within the specified -40°C to +105°C operating range. Check for compliance with RoHS3 regulations if required by project specifications. Validate mechanical fit against existing panel cutouts and board dimensions before procurement.

Selection Notes

Select this component when a robust, low-profile card edge solution is needed for panel integration. The dual-edge design offers increased pin density compared to single-row alternatives while maintaining standard spacing. Consider the gold plating for environments where long-term contact reliability is critical. Evaluate the thermoplastic insulation properties against chemical exposure risks in the deployment environment. Ensure the chosen PCB thickness aligns precisely with the connector's acceptance specifications.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its focus on panel-mount versatility and compatibility with common PCB thicknesses. The 306 series provides a balance between mechanical stability and electrical performance for general-purpose interconnect needs. Components in this family typically feature durable metal alloys and standardized geometries to simplify supply chain management across various electronic designs.

Replacement Considerations

Compatible substitutes include other EDAC 306 series variants with matching position counts and spacing. Cross-reference alternative manufacturers offering dual-edge female connectors with 0.156-inch pitch. Verify that any replacement maintains identical PCB thickness tolerance and mounting style. Ensure environmental ratings and contact materials meet or exceed original specifications.
