306-026-500-103

Overview

The EDAC Inc. 306-026-500-103 is a standard card edge connector designed for high-reliability applications. It features a dual female configuration with 52 positions arranged in two rows, providing a total of 104 contact points. The connector utilizes a 0.156-inch (3.96 mm) pitch to accommodate specific board layouts. Constructed with copper alloy contacts and a Diallyl Phthalate (DAP) housing, it ensures durability. The unit supports through-hole mounting and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Dual female contact configuration for secure card edge insertion
• High-temperature resistant DAP housing material
• Gold-plated copper alloy contacts for reliable conductivity
• Through-hole termination method for PCB integration

Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Automotive electronic module connections
• Military and aerospace instrumentation boards

Procurement Notes

Verify the exact pin count and pitch compatibility with your target circuit board design before ordering. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Check for RoHS compliance status if environmental regulations apply to your project. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this model when a dual-row interface with a 3.96 mm pitch is required. Consider the operating temperature range to ensure suitability for harsh environments. Evaluate the mechanical retention needs against the connector's mounting style. Compare alternative series if different contact densities or housing materials are necessary for the specific application constraints.

Part Context

This component belongs to EDAC’s standard card edge connector lineup, which focuses on robust interconnect solutions for demanding sectors. The 306 series specifically addresses applications requiring durable, high-pin-count interfaces. These connectors are engineered to withstand significant thermal cycling and mechanical stress, making them suitable for long-term deployment in critical infrastructure and specialized electronic systems.

Replacement Considerations

Direct substitutes may include other EDAC models within the 306 series that share identical pitch and position counts. Verify cross-compatibility with existing PCB footprints and mating card dimensions. Consult official EDAC documentation for updated part number revisions or equivalent components with modified housing colors or plating specifications.
