307-020-455-204

Edgeboard Connectors Overview

The EDAC Inc. 307-020-455-204 is a standard card edge connector from the 307 series, designed for reliable signal transmission in electronic assemblies. It features 20 positions with a 3.96 mm pitch and supports dual female contacts for non-specified double-sided card edges. The connector utilizes copper alloy terminals with gold plating to ensure low contact resistance and durability. Rated for 5 A current, it accommodates board thicknesses between 1.37 mm and 1.78 mm. The thermoplastic polyester housing provides insulation resistance of 5 GOhms and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm terminal type, orientation, and flange characteristics. Ensure compatibility with target PCB or card edge thickness specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and compliance status.

Edgeboard Connectors Selection Notes

Select this component when a robust, panel-mountable solution is required for double-sided card edge applications. The 3.96 mm pitch and 5 A rating suit moderate-density industrial environments. Confirm that the operating temperature range aligns with the system's thermal requirements and that the housing material meets necessary environmental standards.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting options, providing engineers with flexible interconnection solutions for diverse hardware architectures requiring reliable mechanical and electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting styles or terminal types. Verify cross-compatibility by comparing dimensional drawings and electrical ratings with alternative EDAC part numbers.
