306-023-521-103

Overview

The EDAC Inc. 306-023-521-103 is a standard card edge connector receptacle designed for high-reliability applications. It features 46 positions arranged in a dual female configuration with a 0.156-inch (3.96 mm) contact spacing. The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts and gold plating, it ensures stable electrical performance. The housing utilizes thermoplastic polyester material, providing robust insulation and mechanical stability.

Feature Summary

• Dual female contact configuration for secure board retention
• Low profile insulator body design for space-constrained assemblies
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing for thermal stability

Applications

• High temperature electronic systems requiring reliable interconnects
• Industrial control panels utilizing double-sided card edge modules
• Aerospace instrumentation with strict dimensional constraints
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific ordering suffix to confirm contact spacing, board thickness compatibility, and mounting style before procurement. Ensure that the selected variant matches the required dual female configuration and thermoplastic polyester housing material. Cross-reference the manufacturer datasheet to confirm compliance with environmental operating temperatures and insulation resistance specifications for the intended application environment.

Selection Notes

Select this component when a dual-row connection is required for a 0.062-inch thick PCB. The 0.156-inch pitch accommodates standard edge card layouts while maintaining low profile requirements. Evaluate the thermoplastic polyester housing for thermal endurance against polyphenylene sulfide alternatives if higher temperature ratings are necessary. Confirm that the floating eyelet mounting option aligns with the chassis design for proper alignment during insertion.

Part Context

This part belongs to the EDAC 306 series of edgeboard connectors, which are engineered for demanding industrial environments. The series offers various position counts and mounting configurations to support diverse system architectures. As a receptacle type, it interfaces directly with double-sided card edge modules, providing a secure mechanical lock and consistent electrical contact throughout the operational lifecycle of the connected hardware.

Replacement Considerations

Compatible substitutes include EDAC 306-023-521-107 and 306-023-521-103 variants within the same series. Verify that alternative parts maintain the identical 0.156-inch pitch and 46-position count. Ensure that the replacement maintains the dual female gender and compatible board thickness specification to guarantee mechanical fit and electrical continuity without redesigning the host panel.
