306-022-500-178

Overview

The EDAC Inc. 306-022-500-178 is a standard card edge connector receptacle from the 306 Series, designed for through-hole panel mount installation. It features a dual female configuration with 44 positions arranged in two rows of 22. The contact spacing is 0.156 inches (3.96 mm), and it utilizes wire hole termination with gold plating on copper alloy contacts. The unit supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-row female architecture providing 44 total connection points for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester housing offers structural stability and thermal endurance
• Wire hole termination style facilitates secure soldering to printed circuit boards

Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument cards
• Automotive electronic control units

Procurement Notes

Verify that the specific part number matches the required 44-position dual-row configuration and 3.96 mm pitch before procurement. Confirm that the operating environment remains within the specified -40°C to +105°C temperature range. Ensure the target PCB design accommodates the 1.37 mm to 1.78 mm card thickness constraint. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Validate that the wire hole termination method aligns with the manufacturing process capabilities.

Selection Notes

Select this component when a robust, high-current capable card edge solution is required for panel-mounted applications. The 306 series provides a balance of mechanical durability and electrical performance suitable for demanding environments. Consider the dual-row layout if space efficiency is critical compared to single-row alternatives. Verify that the gold plating thickness meets long-term reliability requirements for the intended mating cycles. Ensure compatibility with existing tooling for the specified contact spacing.

Part Context

This connector belongs to EDAC's 306 Series, which specializes in standard card edge connectors for general-purpose industrial and commercial applications. The series is characterized by its use of thermoplastic polyester insulation and copper alloy contacts. It serves as a reliable interconnect solution for edgeboard systems where consistent signal integrity and mechanical stability are prioritized over miniaturization.

Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch, such as the 306-022-500-107 variant, provided the mounting style and termination type remain compatible. Cross-series replacements require careful verification of dimensional tolerances and electrical ratings to ensure functional equivalence without redesigning the host PCB footprint.
