306-034-420-108

Overview

The EDAC Inc. 306-034-420-108 is a standard card edge connector receptacle featuring 68 positions arranged in a dual-edge female configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a single centerline row design. The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are tin-plated copper alloy, and the housing is constructed from green thermoplastic polyester. It supports panel mount installation at a vertical angle.

Feature Summary

• Dual-edge female receptacle design for secure board retention
• Low-profile insulator body construction
• Vertical panel mount installation style
• Thermoplastic polyester housing material

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• General-purpose electronic assembly connections

Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination type. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm that the dual-edge configuration aligns with the target board layout. Check current availability status as distribution may vary by region. Validate RoHS compliance requirements against project specifications before finalizing procurement.

Selection Notes

Select this connector when a high-density interface with 68 positions is required for dual-edge card applications. The 3.96 mm pitch provides robust mechanical stability for larger modules. Consider the vertical mounting orientation for space-constrained panel designs. Evaluate the tin-plated contacts for cost-effective general-purpose use rather than high-corrosion environments. Ensure the PCB manufacturing capabilities support the specified 1.57 mm thickness constraint.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and configurations to accommodate different board sizes. The 306 series is characterized by its low-profile design and reliable thermal plastic polyester insulation. It serves as a foundational interconnect solution for modular electronic systems requiring durable and standardized connections.

Replacement Considerations

Direct substitutes within the same series include part numbers such as 306-034-420-104 and 306-034-421-108. Verify that alternative parts maintain the identical 68-position count and 3.96 mm pitch. Cross-reference the contact plating options, as variations between tin and gold affect environmental resistance. Ensure the replacement maintains the dual-edge female configuration and vertical panel mount compatibility.
