306-025-420-104

Overview

The EDAC Inc. 306-025-420-104 is a standard card edge connector receptacle featuring 50 positions with a 3.96 mm pitch. Designed for dual-edge board insertion, it utilizes gold-plated copper alloy contacts and a green thermoplastic housing. The component supports panel mount installation at a vertical angle and accommodates PCB thicknesses of 1.57 mm. It offers a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female contact configuration for secure board retention
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount design facilitates direct chassis integration

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm plating type and housing color variations. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required contact material and insulation resistance ratings for the intended application environment.

Selection Notes

Select this connector when a 3.96 mm pitch dual-edge interface is required for vertical panel mounting. Consider the 5 A current rating and 105°C maximum operating temperature for thermal management planning. Verify that the target printed circuit board thickness aligns with the 1.57 mm specification. Evaluate the gold plating requirement against cost constraints and environmental exposure needs.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and pitch options for general-purpose electronic interconnections. The 306 series is characterized by robust mechanical retention and standardized dimensions suitable for widespread industrial adoption.

Replacement Considerations

Cross-reference part numbers within the EDAC 306 series for alternative position counts or pitch variations. Verify mechanical footprint compatibility before substituting with other manufacturers' products. Ensure electrical ratings match or exceed original requirements.
