305-076-500-512

Edgeboard Connectors Overview

The EDAC Inc. 305-076-500-512 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-edge configuration with 76 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and finished with gold plating to ensure reliable conductivity. The insulator body is made of thermoplastic polyester, providing structural integrity and electrical insulation.

Edgeboard Connectors Feature Summary

• Dual-edge design accepts two-sided card edge PCBs for high-density signal routing
• Low-profile insulator body reduces overall assembly height requirements
• Gold-plated copper alloy contacts provide durable connection surfaces
• Panel mount vertical installation style ensures secure mechanical fixation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing reliable vertical interconnects
• Test and measurement instrumentation with modular card architectures

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, termination type, and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the part number with official EDAC documentation to validate availability and compliance status, as distributor listings may not reflect real-time stock or updated manufacturing revisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 76-position interface is required for vertical panel mounting. Confirm that the application environment falls within the operating temperature range of -40°C to +105°C. Evaluate the need for gold-plated contacts versus alternative finishes based on corrosion resistance requirements. Ensure the mating card edge thickness aligns with the specified 0.062-inch nominal dimension for proper insertion force and retention.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and configurations to suit different density needs. The 305-076-500-512 variant specifically addresses applications requiring a high number of connections in a compact vertical footprint, leveraging the established reliability of the 305 family design.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 76-position count, 3.96 mm pitch, dual-edge configuration, and vertical panel mount style. Verify that any alternative part supports the same 1.57 mm PCB thickness and operates within the -40°C to +105°C temperature range. Consult EDAC's official cross-reference guides for approved equivalent part numbers.
