305-076-520-278

Edgeboard Connectors Overview

The EDAC 305-076-520-278 is a standard card edge connector header featuring 76 positions with a 3.96 mm pitch. It utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Designed for panel mount installation at a vertical angle, this component accommodates printed circuit boards with a nominal thickness of 1.57 mm. The housing is constructed from thermoplastic material, providing structural integrity and insulation.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and terminal styles. Confirm that the thermal and mechanical specifications align with the target application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-row header with 76 positions and 3.96 mm spacing is required. Ensure the mating card edge board thickness matches the 1.57 mm design specification. Consider the vertical panel mount style for space-constrained enclosures where direct board insertion is not feasible.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, maintaining consistent 3.96 mm contact spacing across the lineup to support standardized interface designs in modular electronic architectures.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for cross-referenced part numbers. Verify that any substitute maintains identical 76-position count, 3.96 mm pitch, and panel mount vertical orientation to ensure mechanical fit.
