Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange dimensions. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel mounting style and electrical ratings for the intended application environment.

Edgeboard Connectors Selection Notes

Select this model when a 38-position dual-edge interface is required with a 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the panel mount style aligns with the mechanical assembly requirements. Compare against other series members if different position counts or mounting styles are needed.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which provides standard card edge connectors for various industrial applications. The series offers multiple position counts and mounting options, including panel and PCB mount configurations. The 305-038-556-203 specifically addresses needs for dual-edge connections with robust mechanical retention via its flanged design.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or mounting styles. Cross-reference part numbers within the same series for equivalent electrical characteristics. Verify mechanical fit and pinout compatibility before substituting.
