306-027-421-108

Overview

The EDAC Inc. 306-027-421-108 is a standard card edge connector receptacle featuring 54 positions with a 3.96 mm (0.156 inch) contact spacing. It utilizes a single centerline row design and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs tin-plated copper alloy contacts rated for 5 A current and offers panel mount installation in a vertical orientation. The housing is constructed from thermoplastic polyester, providing insulation resistance of 5 GOhms.

Feature Summary

• Accepts nominal 0.062 inch thick PCBs
• Low profile insulator body design
• Single centerline row configuration

Applications

• Panel-mounted electronic assemblies requiring dual-edge card connection
• Industrial control systems utilizing standard thickness circuit boards
• High-density signal routing in vertical mounting configurations

Procurement Notes

Verify the specific contact plating specification against official datasheets, as distributor listings may indicate variations such as tin or gold finishes for similar part numbers within the 306 series. Confirm that the required board thickness aligns precisely with the 0.062 inch nominal tolerance to ensure proper mechanical retention and electrical contact integrity during operation.

Selection Notes

Select this component when a high-position-count connector with wide 0.156 inch spacing is required for robust mechanical stability. Ensure the application supports vertical panel mounting and utilizes thermoplastic polyester compatible environments. Verify that the 5 A current rating per contact meets the system's electrical load requirements without necessitating derating due to ambient temperature conditions.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors, designed for reliable interconnection between edgeboards and backplanes. The series emphasizes low-profile construction and versatile mounting options, catering to applications demanding durable connections in constrained spaces while maintaining compatibility with standard industry board thicknesses.

Replacement Considerations

Cross-reference with other 306 series variants such as 306-027-421-168 for potential alternative termination or material specifications. Ensure any substitute maintains the identical 54 position count, 3.96 mm pitch, and 0.062 inch board thickness acceptance to guarantee mechanical fit and functional equivalence.
