305-038-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-038-500-278 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features 38 positions with a 3.96 mm pitch and supports a 1.57 mm board thickness. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. Rated for 5 A current, it offers 5 GOhms insulation resistance and operates between -40°C and +105°C. This dual-edge female header uses solder lug termination.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural integrity and insulation
• Vertical panel mount style facilitates direct chassis integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact pin count, termination type, and plating specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm. Confirm that the panel mounting requirements align with the vertical orientation design. Cross-reference the RoHS compliance status with current regulatory standards for your region before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge interface is required for panel-mounted applications. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the 5 A rating meets the circuit load requirements. Consider the vertical orientation for space-constrained enclosures where front-panel access is necessary. Ensure the thermoplastic housing material withstands the environmental temperature range of the deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its durable construction and versatile mounting options. Similar parts in the series vary primarily by position count and termination style. The 305 series is widely used in industrial and commercial electronics requiring reliable mechanical and electrical connections for plug-in boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical pitch and position counts but different termination styles, such as 305-038-520-278 (solder pin) or 305-038-555-278. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure the alternative part number matches the required current rating and operating temperature range.
