306-027-520-101

Overview

The EDAC Inc. 306-027-520-101 is a standard card edge connector from the 306 series, designed for vertical panel mounting. It features 54 positions with a 0.156-inch (3.96 mm) contact spacing and utilizes dual-edge female contacts. The connector supports a PCB thickness of 1.57 mm and offers a current rating of 5 A per contact. Gold plating on copper alloy contacts ensures reliable conductivity, while the thermoplastic housing provides structural integrity. It operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Vertical panel mount style for fixed installation applications
• Gold-plated copper alloy contacts for enhanced signal reliability
• Thermoplastic housing material for durable mechanical support

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device circuit board interfaces
• Consumer electronics module connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and termination type. Ensure compatibility with the target PCB edge thickness and panel cutout dimensions before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm availability through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a high-density vertical connection is required for single-sided or double-sided edge cards. The 0.156-inch pitch accommodates standard board layouts while providing robust mechanical retention. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify that the panel mount orientation aligns with the system's thermal and spatial constraints.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles to suit different design requirements. EDAC, now part of Northern Technologies, specializes in high-reliability interconnect solutions for demanding environments. The 306 series is characterized by its consistent dimensional standards and durable construction materials.

Replacement Considerations

Direct substitutes within the same series include parts like 306-027-520-103 or 306-027-520-168, which share identical electrical and mechanical specifications but may differ in packaging or minor cosmetic attributes. Always verify pin-to-pin compatibility and housing dimensions before substitution.
