Overview

The EDAC Inc. 306-025-420-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight orientation. It features 50 positions arranged in a dual-edge configuration, utilizing a 0.156-inch (3.96 mm) pitch. The connector accepts board thicknesses ranging from 0.051 to 0.071 inches (1.30 to 1.80 mm). Contacts are constructed from copper alloy with tin plating, rated for 5 A current. The housing is made of green thermoplastic polyester, ensuring durability and stability in electronic assemblies.

Feature Summary

Dual-edge female contact configuration for secure board retention
Through-hole solder termination for robust PCB attachment
Thermoplastic polyester housing providing structural integrity
Copper alloy contacts with tin plating for reliable conductivity

Applications

Industrial control system backplanes
Telecommunications equipment interconnects
Consumer electronics module integration
Test and measurement device interfaces

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact plating and housing color specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm regional availability and shipping restrictions via authorized distributors, as supply status may vary by location. Cross-reference the manufacturer part number with ECAD models for accurate footprint validation during design finalization.

Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for through-hole applications. Consider the 5 A current rating and tin-plated contacts for general-purpose signal and power transmission. Evaluate the straight mounting style against spatial constraints within the enclosure. Verify that the target printed circuit board thickness falls within the specified operational range for optimal mechanical engagement.
