306-031-420-107

Overview

The EDAC Inc. 306-031-420-107 is a standard card edge connector header featuring 62 positions with a 3.96 mm (0.156 inch) pitch. It utilizes a single row of dual female contacts designed for vertical panel mount installation. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The housing is constructed from thermoplastic material, while the contacts are made of copper alloy with gold plating to ensure reliable signal transmission.

Feature Summary

• Features a low-profile insulator body with a single centerline row configuration
• Accepts printed circuit boards with a nominal thickness of 1.57 mm
• Utilizes gold-plated copper alloy contacts for enhanced conductivity

Applications

• Industrial control systems requiring robust board-to-panel connections
• Communication equipment utilizing standard card edge interfaces
• Automotive electronics assemblies needing high-density I/O

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact type and mounting style. Ensure the target application supports the 3.96 mm pitch and 1.57 mm board thickness requirements. Confirm that the 5 A current rating aligns with the system's electrical load. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-density 62-position interface is required within a limited vertical space. The 3.96 mm pitch offers a balance between pin count and spacing compared to finer pitches. Consider the panel mount orientation for integration into chassis designs. Verify that the thermoplastic housing material meets the thermal and mechanical demands of the operating environment.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its .156 inch contact spacing and compatibility with .062 inch thick PCBs. The 306 series provides various position counts and mounting options, serving as a versatile solution for connecting edge cards to backplanes or panels in electronic systems.

Replacement Considerations

Direct substitutes within the same series include parts like 306-032-420-107, which shares identical pitch and board thickness specifications but differs in position count. Cross-series replacements require matching the 3.96 mm pitch and 1.57 mm board thickness constraints to ensure mechanical fit.
