306-023-421-178

Overview

The EDAC Inc. 306-023-421-178 is a standard card edge connector receptacle featuring 23 positions in a single row with a 3.96 mm (0.156 inch) contact spacing. Designed for panel mount installation, it utilizes solder pin termination and gold-plated copper alloy contacts rated for 5 A current. The thermoplastic polyester housing supports PCB thicknesses of 1.57 mm nominal. It operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Feature Summary

• Single-row female configuration with gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator body providing structural integrity and electrical isolation
• Panel mount design with vertical orientation and solder pin termination for secure board attachment

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB form factors
• Consumer electronics assemblies needing high-reliability interconnects

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, housing color, and flange specifications. Ensure the target application matches the 1.57 mm nominal PCB thickness requirement. Confirm RoHS compliance status through the latest certified documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-row, 23-position interface with 3.96 mm pitch is required. The gold plating offers superior corrosion resistance compared to tin alternatives. Verify that the mechanical constraints of the enclosure allow for the specified panel mount dimensions and vertical profile requirements.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and mounting options. The 306-023-421-178 specifically denotes the 23-position variant with standard gold plating and thermoplastic construction, distinct from high-temperature or dual-edge variants.

Replacement Considerations

Cross-reference with EDAC 306-023-421-102 if tin plating is acceptable. Check 307-023-431-178 for similar positioning but verify pitch compatibility. No direct substitutes are confirmed without verifying mechanical and electrical parameter alignment.
