306-033-421-101

Overview

The EDAC Inc. 306-033-421-101 is a standard card edge connector receptacle from the 306 series. It features 66 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card configurations. Designed for panel mount installation, it utilizes solder pin termination and copper alloy contacts with tin plating. The housing is constructed from green thermoplastic polyester, accommodating board thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A current at operating temperatures ranging from -40°C to 105°C, this component ensures reliable electrical connectivity in industrial applications.

Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Panel mount design with flange features for stable mechanical attachment
• Copper alloy contacts with tin plating for corrosion resistance

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct contact plating and housing color specifications. Confirm that the target application requires a dual-edge receptacle rather than a single-edge variant. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 and REACH regulations if required by project standards before finalizing procurement orders.

Selection Notes

Select this model when a high-density 66-position interface is required for double-sided PCB connections. The 3.96 mm pitch accommodates standard board thicknesses within the specified range. Consider the tin-plated contacts for general-purpose environments where gold plating is not strictly necessary. Verify that the vertical mounting orientation aligns with the chassis design constraints and thermal management requirements of the assembly.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors, designed for robust industrial and commercial electronics. The series offers various position counts and mounting styles to support diverse board-to-board and board-to-panel interfaces. The 306-033-421-101 specifically addresses needs for dual-edge connectivity with a focus on durability and standardized spacing for widespread compatibility.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with identical mechanical dimensions and electrical ratings. Verify cross-compatibility with existing PCB footprints and mating card edge profiles before substitution.
