305-042-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-207 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 42 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector accepts non-specified dual-edge cards with a thickness range of 1.37 mm to 1.78 mm. Contact plating is gold over copper alloy, and the housing is green thermoplastic polyester. It supports solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and flange specifications. Ensure compatibility with target PCB card thickness limits before procurement. Confirm RoHS3 compliance status through current manufacturer datasheets as regulatory requirements may evolve. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a high-density 42-position interface is required for dual-edge card applications. The 3.96 mm pitch offers a balance between signal density and mechanical stability. Consider the vertical panel mount style for chassis integration where space constraints favor upright installation. Verify that the 5A current rating meets the system's power distribution requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized solutions for card edge interfacing. The series is known for its versatility in accepting various polarizing keys and card types. The 305-042 variant specifically addresses applications needing a moderate number of connections with high reliability standards typical of industrial-grade hardware.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-042-520-202 and 305-042-521-503. Verify that alternative suffixes match the required termination type and flange dimensions. Consult EDAC cross-reference guides for compatible parts with similar electrical ratings and physical footprints.
