306-026-421-168

Overview

The EDAC Inc. 306-026-421-168 is a dual-edge female card edge connector designed for board-to-board or backplane interconnections. It features 52 positions with a contact spacing of 0.156 inches (3.96mm). The connector utilizes tin-plated contacts and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with a low-profile insulator body, this component supports single centerline row configurations. It is intended for applications requiring reliable mechanical stability and electrical continuity in industrial and commercial environments.

Feature Summary

• Accepts PCBs with a nominal thickness of 0.062 inches (1.57mm)
• Features a low-profile insulator body design
• Utilizes tin-plated contacts for corrosion resistance

Applications

• Industrial control systems
• Commercial computing hardware
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix to ensure the correct contact plating and termination style match the design requirements. Confirm that the target PCB thickness falls within the specified acceptance range of 0.062 inches. Check for any environmental certifications required by the end application. Ensure the mounting orientation aligns with the assembly layout. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing the procurement order.

Selection Notes

Select this connector when a 0.156-inch pitch is required for high-density signal routing. The dual-edge configuration allows for increased pin count within a limited footprint. Consider the tin plating for general-purpose applications where gold plating is not strictly necessary. Evaluate the low-profile height constraints of the enclosure to ensure proper clearance. Verify compatibility with standard PCB manufacturing processes for the specified board thickness.

Part Context

This component belongs to the EDAC 306 series of card edge connectors. The series is characterized by its robust construction and versatile positioning options. It serves as a critical interconnect solution in modular electronic systems. The part number structure indicates specific attributes regarding position count, contact type, and plating. Understanding the series context helps in identifying compatible mating components and accessories.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacements must be verified against mechanical dimensions and electrical specifications. Ensure any alternative component matches the 0.156-inch spacing and 52-position requirement. Consult the manufacturer for potential obsolescence notices or recommended upgrades.
