Overview
The EDAC Inc. part number 306-027-521-168 is a dual female card edge connector featuring 82 positions. It utilizes a contact spacing of 0.156 inches (3.96mm) with a single centerline row configuration. The component is designed to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). It incorporates a low-profile insulator body and tail-type contacts for board mounting.
Feature Summary
- Dual female contact configuration for secure card edge mating
- Single centerline row design accommodating standard PCB thicknesses
- Low-profile insulator body construction for compact assembly
Applications
- Industrial control systems requiring robust card edge interfaces
- Communication equipment utilizing modular board architectures
- Medical devices needing reliable high-density connections
Procurement Notes
Verify the specific manufacturer datasheet for the 306-027-521-168 to confirm exact mechanical dimensions and material specifications. Ensure compatibility with the target PCB stack-up, particularly regarding the 0.062-inch nominal thickness requirement. Cross-reference the official EDAC documentation for any updates on plating details or environmental ratings before finalizing procurement orders.
Selection Notes
Select this component when a dual female card edge connector with 82 positions is required. The 0.156-inch pitch suits applications needing moderate density without excessive miniaturization. Consider the low-profile body height if vertical clearance within the enclosure is limited. Validate that the single centerline row aligns with the signal routing strategy of the associated circuit board design.
Part Context
This connector belongs to the EDAC 306 Series, which specializes in card edge solutions. The series offers various contact counts and termination options tailored for diverse electronic assemblies. The 306-027-521-168 specifically addresses needs for higher pin counts in a dual female format, supporting stable electrical connections in demanding operational environments.
Replacement Considerations
Consult official EDAC catalogs for direct substitutes within the 306 series. Verify that alternative part numbers match the 82-position count and 0.156-inch spacing exactly. Ensure any replacement maintains the dual female configuration and compatible PCB thickness tolerance.
