346-038-500-202

Edgeboard Connectors Overview

The EDAC Inc. 346-038-500-202 is a standard card edge receptacle connector from the 346 series, designed for vertical through-hole mounting on printed circuit boards. It features 38 positions with a 3.175 mm (0.125 inch) contact spacing and accommodates dual-edge card configurations. The contacts are gold-plated copper alloy, rated for 3 A current, while the housing is constructed from green thermoplastic polyester. This component supports PCB thicknesses of approximately 1.57 mm and utilizes PC pin termination for secure board integration.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural stability and environmental protection
• Vertical through-hole design facilitates direct PCB integration without additional brackets

Edgeboard Connectors Applications

• General-purpose electronic equipment interconnection
• Industrial control system module connections
• Communication infrastructure hardware assembly

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific contact plating, housing color, and termination style variations. Ensure compatibility with the target PCB stack-up and card edge thickness specifications before ordering. Confirm RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this model when a 38-position vertical card edge interface is required with standard 0.125-inch spacing. Consider the 3 A current rating and gold contact finish for applications demanding durable electrical performance. Evaluate mechanical retention needs as this is a receptacle type requiring mating with a corresponding card edge connector.

Edgeboard Connectors Part Context

This component belongs to the EDAC 346 series of standard card edge connectors, which offers a wide range of position counts and configurations. The series is characterized by its robust construction using thermoplastic polyester insulators and versatile mounting options suitable for various industrial and commercial electronics applications requiring reliable board-to-board or board-to-card connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants with different position counts such as 346-020-500-102 or 346-050-555-812, provided the pin count matches the design requirements. Cross-series replacements like the 846 high-temperature series may be considered if thermal performance is critical, though mechanical dimensions must be verified.
