Overview
The EDAC Inc. 306-025-521-107 is a standard card edge connector from the 306 series, designed for panel mounting applications. It features a dual-edge female configuration with 50 positions arranged in two rows of 25 contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.
Feature Summary
- Dual-edge female contact configuration for secure board insertion
- Panel mount installation style with integrated M3 threaded inserts
- Gold-plated copper alloy contacts ensuring reliable conductivity
- Thermoplastic polyester insulation providing thermal stability
Applications
- Industrial control panel interconnections
- Rack-mounted electronic equipment interfaces
- High-density signal routing in modular systems
Procurement Notes
Verify that the specific part number matches the required 50-position dual-edge specification and M3 threaded insert mounting style. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment falls within the specified -40°C to +105°C operating temperature limits. Check RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a panel-mount solution with high mechanical stability is required. The M3 threaded inserts provide superior retention compared to snap-fit alternatives. Choose this model for applications requiring a 3.96 mm pitch and dual-edge access. Consider the gold plating for environments where corrosion resistance is critical. Verify that the 5 A current rating meets the electrical requirements of the connected circuitry.
Part Context
This connector belongs to the EDAC 306 series, which specializes in robust card edge solutions for demanding industrial environments. The series offers various position counts and mounting options, including panel and PCB mount styles. The 306-025-521-107 variant specifically addresses needs for dual-edge connectivity with fixed panel mounting capabilities.
Replacement Considerations
Direct substitutes within the same series include 306-025-521-178, which shares identical electrical and mechanical specifications but may differ in packaging or minor cosmetic attributes. Cross-series replacements require verification of pitch, position count, and mounting interface compatibility.
