Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and material specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the required current rating of 5 A aligns with the system design parameters. Check for RoHS compliance status relevant to the procurement region. Validate lead times directly with authorized distributors as availability may vary.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with 54 positions is required for vertical panel installation. The 3.96 mm pitch suits applications needing wider spacing between rows compared to finer pitches. Consider the 5 A current rating for power distribution needs within the connector interface. The thermoplastic polyester housing offers durability for industrial environments. Ensure the mounting style matches the chassis design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and mounting options to accommodate different board densities. The 305-054 variant specifically addresses applications requiring a higher pin count while maintaining the standard 0.156 inch spacing characteristic of the family.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-054-520-202 or 305-054-520-502 if variations in housing color or specific flange characteristics are acceptable. Verify that any substitute maintains the identical 54-position count and 3.96 mm pitch to ensure mechanical fit.
