305-048-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-048-520-503 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 48 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). It utilizes gold-plated copper alloy contacts with a half-beam termination style for reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness and housing color variations. Ensure compatibility with the target PCB stack-up and panel mounting requirements. Cross-reference the RoHS status and REACH compliance data directly from the source documentation before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with high current capacity is required. The 3.96 mm pitch suits applications needing robust mechanical locking without excessive density. Consider the vertical panel mount style and solder pin termination for fixed installation scenarios requiring durable long-term connectivity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are engineered for general-purpose industrial and commercial electronics. The series offers various position counts and termination styles, providing flexibility for different board densities. The 305 series is characterized by its reliability in harsh environments and standardized dimensions for easy integration into existing chassis designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series that share identical 48-position counts and 3.96 mm spacing, such as 305-048-500-201 or 305-048-520-501, provided the specific suffix matches the required plating and housing specifications.
