306-017-421-178

Edgeboard Connectors Overview

The EDAC Inc. 306-017-421-178 is a standard card edge connector receptacle featuring 34 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). The component employs tin-plated copper alloy contacts for termination via solder pins, supporting a current rating of 5 A. Designed for panel mount installation, the housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and material specifications. Ensure the selected variant matches the required PCB thickness tolerance and mounting orientation. Cross-reference the part number with authorized distributors to confirm availability and compliance with current environmental directives such as RoHS standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper contact engagement. Verify that the tin-plated termination method aligns with the assembly process and that the 5 A current rating meets the application's electrical requirements.
