305-042-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-508 is a standard card edge connector from the 305 series, designed for panel mount applications 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 utilizes gold-plated copper alloy contacts and a green thermoplastic housing. It supports solder pin termination and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB edge thickness tolerances before procurement. Confirm RoHS compliance status through manufacturer datasheets rather than distributor summaries. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 42 positions is required. The 3.96 mm pitch suits applications needing wider spacing between contacts. Verify that the vertical panel mount style aligns with mechanical constraints. Consider the 5 A current rating for power distribution needs. Ensure the operating temperature range meets environmental requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-042 variant specifically addresses mid-range density requirements. It complements other EDAC products like the 305-048 and 305-054 models for scalable system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-042-520-202 and 305-042-500-504. Verify pinout and mechanical dimensions match before substitution. Check if alternative suffixes offer different plating or housing colors without affecting electrical performance.
