306-025-500-108

Overview

The EDAC Inc. model 306-025-500-108 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features 50 positions in a dual female configuration with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The unit operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Feature Summary

• Dual-edge female contact design for secure board retention
• Gold-plated copper alloy contacts ensure reliable conductivity
• Vertical panel mount style with low-profile insulator body

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Procurement Notes

Verify the specific suffix requirements against the official EDAC ordering guide to ensure correct plating thickness and material specifications. Confirm that the target PCB thickness aligns with the 1.57 mm acceptance criteria. Check current supply chain status as availability may be restricted or subject to long lead times depending on regional distribution channels.

Selection Notes

Select this component when a dual-sided card edge interface is required for vertical panel mounting. Ensure the application demands a 3.96 mm pitch and robust gold contact plating. Verify that the housing color and thermal rating meet environmental constraints. Compare against single-row variants if space limitations require a different footprint configuration.

Part Context

This part belongs to the EDAC 306 series of standard density card edge connectors. The series offers various position counts and mounting styles. The 306-025-500-108 specifically denotes a 50-position dual-edge variant. It is engineered for high-reliability applications requiring stable electrical connections in demanding environments.

Replacement Considerations

Consult the EDAC 306 series ordering guide for direct substitutes with differing position counts or plating options. Cross-reference compatible parts from other manufacturers only if mechanical dimensions and electrical ratings match precisely.
