306-028-400-103

Overview

The EDAC Inc. 306-028-400-103 is a dual female card edge connector featuring 56 positions arranged in two rows of 28. It utilizes a 0.156-inch (3.96mm) contact spacing with a single centerline row configuration. The component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Designed for through-hole termination, it operates within a temperature range of -40°C to 105°C and incorporates a low-profile insulator body.

Feature Summary

• Dual female contact configuration providing 56 total connection points across two rows
• Accepts standard 0.062-inch nominal thickness printed circuit boards
• Low-profile insulator body design for compact assembly requirements

Applications

• High-density electronic board interconnections
• Industrial control system module interfaces
• Telecommunications equipment backplane connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required termination styles and mounting configurations. Confirm that the dual female contact type aligns with the mating card edge design. Check RoHS compliance status and environmental ratings against project specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual-row interface is required for 0.062-inch thick substrates. The 0.156-inch pitch supports high pin counts in limited space. Ensure the application environment remains within the specified -40°C to 105°C operational range. Validate mechanical clearance for the low-profile body height during PCB layout planning.

Part Context

This part belongs to the EDAC 306 series of edgeboard connectors. The series offers various position counts and termination options. It serves as a standard solution for vertical board-to-board or board-to-backplane connections in industrial and commercial electronics applications requiring reliable signal transmission.

Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 306 series designation, dual female contact style, 56-position count, and 0.156-inch pitch. Verify identical board thickness acceptance and termination method before cross-referencing.
