306-028-521-107

Overview

The EDAC Inc. 306-028-521-107 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features 33 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The housing is constructed from thermoplastic material, providing durability and insulation resistance of 5 GOhms. The current rating is specified at 5 A.

Feature Summary

• Vertical panel mount design for secure installation
• Gold-plated copper alloy contacts for conductivity
• Thermoplastic insulator body for structural integrity

Applications

• Industrial control systems requiring robust interconnects
• Communication equipment board connections
• Medical device internal circuitry integration

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm pin count, termination type, and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the vertical panel mount style aligns with the mechanical assembly requirements. Cross-reference the 33-position configuration with system design schematics to prevent mismatch errors during procurement.

Selection Notes

Select this component when a single-row female card edge connector with 3.96 mm pitch is required. The vertical orientation suits panel-mounted designs where space efficiency is critical. The 5 A current rating supports moderate power applications. Verify that the gold contact finish meets environmental corrosion resistance needs. Ensure the thermoplastic housing material is compatible with the operating temperature range of the intended application environment.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-028-521-107 specifically denotes a 33-position variant with dual-edge female contacts. It is engineered for general-purpose electronic assemblies requiring reliable board-to-board or board-to-panel connections in industrial and commercial sectors.

Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different termination or housing colors. Verify mechanical dimensions and electrical ratings before swapping. No alternative part numbers are explicitly confirmed as direct replacements in public documentation without further specification matching.
