306-029-421-168

Overview

The EDAC Inc. 306-029-421-168 is a dual-edge female card edge connector from the 306 Series, designed for panel mount and through-hole termination. It features 58 positions with a 0.156-inch (3.96mm) contact spacing and tin-plated contacts. The insulator is green polyester thermoplastic, supporting PCB thicknesses of 0.062 inches (1.57mm). Rated for -40°C to +105°C, it utilizes cantilever spring contacts for reliable signal transmission in standard industrial applications.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for secure board retention
• Flush mount flange with top opening for standardized panel integration
• Tin-plated copper alloy terminals ensuring corrosion resistance and conductivity
• Green polyester thermoplastic insulation body rated for high-temperature environments

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics motherboard connections
• Medical device circuit board interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating type, and mounting style. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference the RoHS status and moisture sensitivity level requirements with project standards to guarantee regulatory compliance and storage stability during assembly processes.

Selection Notes

Select this component when a 0.156-inch pitch dual-edge connector is required for panel-mounted applications. The 58-position count suits moderate-density designs. Verify that the target printed circuit board thickness aligns with the specified 0.062-inch nominal requirement. Consider the operating temperature range of -40°C to +105°C for environmental suitability in industrial or commercial settings.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for robust mechanical performance. The series offers various position counts and termination options. The 306-029-421-168 specifically addresses needs for dual-edge connectivity with flush mounting capabilities, serving as a critical interface component in modular electronic systems requiring reliable signal integrity.

Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitutes. Ensure replacement parts match the 0.156-inch pitch, 58-position count, and dual-edge female configuration. Verify identical mounting styles and thermal ratings to maintain system compatibility without redesigning the host PCB layout.
