Overview
The EDAC Inc. 306-025-400-178 is a dual-edge female card edge connector designed for panel mount installation. It features 50 positions with a 0.156-inch (3.96mm) pitch arranged in a single centerline row. The connector utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The unit employs solder eyelet termination and includes card guides for secure insertion.
Feature Summary
- Dual-edge female configuration with 50 positions
- Tin-plated copper alloy contacts for reliable connection
- Green thermoplastic polyester insulator body
- Panel mount installation with integrated card guides
Applications
- Industrial control systems requiring robust board-to-board connectivity
- Test and measurement equipment interfaces
- General-purpose electronic assemblies using standard thickness PCBs
Procurement Notes
Verify the contact plating specification, as some sources indicate tin while others suggest gold for similar series variants. Confirm the exact board thickness tolerance required for proper engagement with the card guides. Ensure the panel mounting hole pattern matches the mechanical drawing specifications before finalizing the design integration.
Selection Notes
Select this component when a low-profile, high-density connection is needed for 1.57mm thick boards. The 0.156-inch pitch allows for fewer rows compared to finer pitches, simplifying layout. Consider the tin plating for cost-effective applications where frequent mating cycles are not expected. Verify environmental ratings if operating outside standard temperature ranges.
Part Context
This part belongs to the EDAC 306 Series, which focuses on standard card edge connectors. The series offers various position counts and plating options. The 306-025-400-178 specifically addresses the need for a 50-position interface with a durable, low-profile housing suitable for industrial environments.
Replacement Considerations
Direct substitutes within the same series include 306-025-400-101, though plating differences may exist. Cross-reference mechanical dimensions and pinout compatibility carefully. No other manufacturers produce identical form-factor replacements without design modification.
