Overview
The EDAC Inc. part number 306-027-421-168 is a standard card edge connector designed for dual-edge board applications. It features 54 positions with female contacts and a pitch of 0.156 inches (3.96 mm). The connector utilizes tin-plated copper alloy contacts housed in green thermoplastic polyester insulation. It supports a current rating of 5 A and offers an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C, accommodating single-row configurations.
Feature Summary
- Dual-edge female contact configuration for secure board insertion
- Tin-plated copper alloy contacts ensuring reliable conductivity
- Green thermoplastic polyester housing for structural integrity
- Standard spacing compatible with general-purpose circuit boards
Applications
- General-purpose electronic assemblies requiring dual-edge connectivity
- Industrial control systems utilizing standard card edge interfaces
- Communication equipment board interconnections
- Consumer electronics manufacturing processes
Procurement Notes
Verify the specific contact plating material against project requirements, as sources indicate tin plating for this designation. Confirm that the 0.156-inch pitch aligns with the target PCB design specifications. Ensure the thermal rating of plus 105 degrees Celsius meets the operational environment constraints. Cross-reference the 54-position count with the intended signal routing needs to prevent mismatched interface requirements during assembly.
Selection Notes
Select this component when a dual-edge female connector with a 0.156-inch pitch is required. The tin plating offers cost-effective conductivity suitable for non-corrosive environments. Consider the green housing color for visual identification during assembly. Verify compatibility with the target board thickness and mounting style before finalizing the bill of materials.
Part Context
This component belongs to the EDAC standard card edge connector family, which provides various row counts and spacing options. The 306 series specifically addresses dual-edge applications with robust mechanical retention. EDAC Inc., now part of NorComp, manufactures these connectors for diverse industrial and commercial sectors, offering standardized solutions for reliable electrical interconnections.
Replacement Considerations
Direct substitutes within the same series require matching the 54-position count and 0.156-inch pitch. Verify that alternative parts maintain the female contact type and dual-edge orientation. Ensure comparable thermal ratings and insulation resistance values are met by any replacement option.
