306-006-420-178

Edgeboard Connectors Overview

The EDAC Inc. 306-006-420-178 is a standard card edge connector from the 306 Series, designed for dual-edge board insertion. It features 12 positions with 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 connector utilizes tin-plated copper alloy contacts in a single centerline row configuration. It employs a PC tail termination method for through-hole mounting on the PCB. The insulator body is constructed from green thermoplastic material, providing a low-profile design suitable for space-constrained applications requiring reliable electrical interconnection.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm plating type and terminal length. Ensure compatibility with the target PCB stack-up and hole dimensions. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with official EDAC documentation to validate availability and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with 12 positions and 3.96 mm pitch is required. Ensure the application supports tin plating rather than gold. Verify that the PCB thickness matches the 1.57 mm nominal specification. Consider the low-profile form factor for height-restricted enclosures. Confirm that the single-row layout aligns with the signal routing requirements of the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which offers various configurations of card edge connectors. The series provides options for different contact spacings, row counts, and termination styles. The 306-006-420-178 specifically addresses needs for dual-edge insertion with tin-plated contacts. It serves as a standardized solution for connecting edgeboards in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with identical mechanical dimensions. Verify pin count and pitch compatibility before considering alternative manufacturers. Ensure that any replacement maintains the same termination style and plating characteristics to preserve assembly integrity.
