306-021-400-103

Overview

The EDAC Inc. 306-021-400-103 is a dual-edge female card edge connector from the 306 Series, designed for panel mount and through-hole termination. It features 42 positions with a 0.156-inch (3.96mm) contact spacing arranged in a single centerline row. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The unit operates within a temperature range of -40°C to 105°C and meets RoHS3 standards.

Feature Summary

• Dual-edge female configuration with 42 positions for secure board insertion
• Through-hole solder termination ensuring robust mechanical and electrical connections
• Green thermoplastic polyester insulator body providing thermal stability
• Tin-plated copper alloy contacts for reliable signal transmission

Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Consumer electronic device expansion slots
• Medical instrumentation internal connectivity

Procurement Notes

Verify that the specific part number matches the required 42-position count and 0.156-inch pitch before ordering. Confirm that the target PCB thickness aligns with the specified 0.062-inch nominal requirement to ensure proper contact engagement. Check for RoHS3 compliance if environmental regulations apply to the final assembly. Ensure panel mounting holes correspond to the flange specifications provided in the official datasheet.

Selection Notes

Select this component when a dual-edge female connector with 42 pins is required for vertical panel installation. The 0.156-inch spacing suits applications where standard board widths are utilized. Consider the tin plating for general-purpose use rather than high-frequency or corrosive environments requiring gold. Verify that the through-hole mounting style fits the PCB layout constraints compared to surface-mount alternatives.

Part Context

This connector belongs to the EDAC 306 Series, which offers various pin counts and configurations for card edge applications. The series is characterized by low-profile insulator bodies and standardized spacing dimensions. It serves as a standard interconnect solution within EDAC's portfolio for general industrial and commercial electronics, distinct from specialized high-density or high-temperature series.

Replacement Considerations

Cross-reference with other EDAC 306 Series variants such as 306-021-421-103 for identical specifications. Verify compatibility with mating cards having matching edge conductor layouts. Ensure that any substitute maintains the same 0.156-inch pitch and 42-position count to preserve mechanical fit.
