333-021-544-103

Edgeboard Connectors Overview

The EDAC Inc. 333-021-544-103 is a standard card edge connector designed for vertical PCB mounting. It features 18 positions with a single row configuration and a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, rated for 3 A current. The housing is made of green thermoplastic polyester, supporting board thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40 °C to +105 °C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Vertical mounting orientation with flush mount flange featuring top opening
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation providing stable mechanical support

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm contact plating thickness and housing color specifications. Ensure the target printed circuit board thickness falls within the 1.37 mm to 1.78 mm acceptance range for proper insertion. Confirm that the vertical mounting style aligns with the enclosure design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 18-position connection is required with a 3.96 mm pitch. The vertical form factor suits applications where space above the board is available. Verify that the 3 A current rating meets the circuit load requirements and that the operating temperature range covers the environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 333 series of standard density card edge connectors. The series provides various position counts and mounting styles for general-purpose electronic interconnects. The 333-021-544-103 specifically addresses the need for 18-position connections in compact vertical layouts.

Edgeboard Connectors Replacement Considerations

Cross-reference other 333 series variants for different position counts or mounting angles. Verify compatibility with existing tooling and PCB footprints when substituting similar parts from the same manufacturer family.
