305-038-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-578 is a standard card edge connector header featuring 38 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for vertical panel mounting with solder pin termination. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. The housing is made of thermoplastic material, accommodating board thicknesses typically around 1.57 mm.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness and housing color variations. Ensure compatibility with mating card edge thickness specifications before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for your region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and gold contact finish for environments demanding robust conductivity. Verify that the vertical mounting style aligns with the mechanical constraints of the enclosure design and that the 38-position count matches the circuit requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting options, providing a standardized solution for connecting printed circuit boards to system backplanes or chassis panels through reliable soldered interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-038-520-578 or 305-038-521-502, differing primarily in housing material or plating details. Always validate mechanical dimensions and electrical ratings against the original specification sheet before substitution.
