306-031-420-102

Overview

The EDAC Inc. 306-031-420-102 is a standard card edge connector classified as a header within the 306 series. It features 33 positions with a contact spacing of 3.96 mm and accommodates a nominal printed circuit board thickness of 1.57 mm. Designed for panel mount installation at a vertical angle, the component utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The housing is constructed from thermoplastic material, providing structural integrity and electrical insulation. This connector supports a current rating of 5 A and offers an insulation resistance of 5 Gohms, making it suitable for applications requiring robust mechanical and electrical performance in vertical mounting configurations.

Feature Summary

• Dual female contact configuration designed for secure mating with card edge boards
• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance
• Thermoplastic polyester insulator body ensures stable electrical isolation and mechanical support

Applications

• Vertical panel-mounted electronic assemblies
• Industrial control system interconnects
• Telecommunications equipment backplanes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pin count, plating type, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the 3.96 mm pitch aligns with the design requirements. Confirm RoHS compliance status through the latest datasheet before procurement.

Selection Notes

Select this component when a vertical, panel-mount card edge interface is required with a 33-position layout. The 3.96 mm pitch and 1.57 mm board thickness acceptance are critical constraints. Consider the 5 A current rating and gold plating for environments demanding high reliability and low contact resistance over repeated mating cycles.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are engineered for general-purpose interconnection needs. The series typically offers various position counts and mounting styles to accommodate diverse board-to-board or board-to-panel interfaces. The 306-031-420-102 specifically addresses the need for a vertical header configuration with defined electrical ratings.

Replacement Considerations

Cross-reference with other EDAC 306 series headers sharing identical 33-position, 3.96 mm pitch, and 1.57 mm board thickness specifications. Verify that any substitute maintains the same vertical panel mount orientation and gold-plated contact finish to ensure functional equivalence.
