306-022-420-103

Overview

The EDAC Inc. model 306-022-420-103 is a standard card edge connector receptacle designed for vertical panel mount applications. It features a dual female contact configuration with 44 positions arranged in a single centerline row. The component utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The insulator body is constructed from green thermoplastic polyester, providing a low-profile design. Contacts are made of copper alloy with a tin plating finish to ensure reliable electrical connection.

Feature Summary

• Vertical panel mount receptacle design with a low-profile insulator body
• Dual female contact configuration accommodating non-specified dual-edge PCBs
• Tin-plated copper alloy contacts for secure termination
• Green thermoplastic polyester housing material

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• General-purpose electronic module mounting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and orientation details. Ensure the target application requires a 3.96mm pitch and 1.57mm board thickness compatibility. Confirm that the tin-plated contact finish meets the environmental and conductivity requirements of the intended assembly process before finalizing procurement orders.

Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge card insertion. The 44-position capacity and 3.96mm spacing define the interface density. Verify that the tin plating is suitable for the operating environment, as gold-plated alternatives exist within the same series for higher corrosion resistance or lower contact resistance needs.

Part Context

This part belongs to the EDAC 306 Series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-022-420-103 specifically denotes a 44-position variant with tin contacts and a green insulator. It is distinct from other series like the 357 or 837 which may feature different contact types or high-temperature ratings.

Replacement Considerations

Compatible substitutes include other EDAC 306 series parts with matching 44 positions and 3.96mm pitch. Verify pinout and mechanical dimensions against the original specification. Cross-reference with distributor databases for equivalent generic card edge connectors meeting the same electrical and form-factor constraints.
