305-042-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit is panel-mounted vertically with solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing
• Gold-plated semi-bellows contact type for reliable engagement
• Panel mount design with flush mounting flange and top opening
• Compatible with non-specified dual-edge circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct flange and contact plating specifications. Confirm that the target application requires the 3.96 mm pitch and 42-position count. Check RoHS compliance status if restricted substances are mandated by the end product regulations. Ensure the PCB thickness falls within the specified operational range for proper mechanical retention.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch distinguishes it from finer-pitch alternatives. Consider the 5 A current rating for power distribution needs. Verify that the threaded insert flange feature aligns with the chassis mounting hardware. Compare against similar 305 series parts if position counts or mounting styles differ.

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 configurations. The 305-042-556-568 specifically denotes the 42-position variant with dual-edge compatibility. It is distinct from single-row or different pitch connectors within the broader EDAC portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 305 series parts with identical electrical and mechanical parameters but different position counts, such as 305-022-556-568 or 305-054-556-568. Cross-series replacements require verification of pitch, row count, and mounting style compatibility.
