337-078-544-202

Edgeboard Connectors Overview

The EDAC Inc. 337-078-544-202 is a standard card edge connector designed for vertical through-hole mounting. It features a dual female configuration with 78 positions arranged in two rows. The contact spacing is 0.156 inches (3.96 mm), and the row spacing is 0.200 inches (5.08 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are made of copper alloy with gold plating, rated for 3 A current at 5 GOhms insulation resistance. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure board insertion
• High-profile thermoplastic polyester insulator body
• Gold-plated copper alloy contacts for reliable conductivity
• Vertical through-hole termination with wire wrap style

Edgeboard Connectors Applications

• Industrial control system backplanes

• Computing hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct pin count and termination style. Confirm RoHS compliance status and environmental ratings prior to ordering. Check manufacturer lead times as availability may vary. Ensure PCB design matches the specified 0.062-inch thickness requirement for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a dual-row vertical card edge interface is required with 0.156-inch spacing. Verify that the target application supports wire wrap termination methods on the PCB. Ensure the operating environment falls within the specified -40°C to +105°C temperature range. Confirm compatibility with the intended board thickness and mating card dimensions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 337 series of standard card edge connectors. The series offers various position counts and row configurations. These connectors are engineered for robust mechanical stability and electrical performance in demanding environments. The 337 series utilizes high-profile bodies to accommodate thicker boards and provide strain relief.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 337 series parts with identical 78-position dual female specifications. Cross-reference spacing and termination styles carefully. Generic equivalents may lack the specific high-profile body design or gold plating thickness.
