Edgeboard Connectors Procurement Notes

Verify part authenticity through authorized EDAC distributors or official channels. Confirm RoHS compliance status and specific packaging quantities prior to order placement. Ensure compatibility with target PCB dimensions and mounting requirements. Request updated datasheets to validate latest manufacturing revisions. Cross-reference ordering suffixes to confirm exact contact plating and housing color specifications.

Edgeboard Connectors Selection Notes

Select this component when dual-edge board connectivity is required with a 3.96 mm pitch. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm range for proper fit. Consider the vertical panel mount style and flush flange design for enclosure integration. Ensure the 5 A current rating meets circuit demands. Confirm that gold-plated semi-bellows contacts align with signal integrity and durability needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting styles for card edge applications. The series is characterized by thermoplastic polyester housings and copper alloy contacts. Similar parts in the series vary by position count, such as 22 or 48 positions, and may differ in mounting angles or flange configurations while maintaining consistent pitch and material properties.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include variants like 305-020-556-202, which shares identical electrical and mechanical specifications. Verify that alternative part numbers maintain the same 20-position count, 3.96 mm pitch, and dual-edge female configuration. Ensure matching flange dimensions and termination types before substitution.
