Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and flange configurations. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for your specific application requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 44-position interface is required for vertical mounting applications. The 2.54 mm pitch aligns with standard board layouts, while the gold plating supports frequent mating cycles. Consider the -40°C to +105°C operating range for environments with significant thermal variations. Verify that the flush mount or floating bobbin flange options match the chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, which specializes in standard card edge connectors for various industrial and commercial sectors. The series offers multiple position counts and row configurations to accommodate diverse connectivity needs. Components in this line are engineered for reliability in demanding environments, providing consistent performance for critical electronic connections in modern hardware designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch, such as the 345-044-521-202 variant. Verify mechanical fit and electrical ratings before swapping. Generic equivalents may lack the specific flange features or material specifications of the original EDAC component.
