392-078-542-201

Edgeboard Connectors Overview

The EDAC Inc. 392-078-542-201 is a standard card edge connector from the 392 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 78 positions arranged in two rows, providing a total of 78 contact points. The connector utilizes a 0.100-inch (2.54mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches. Constructed with copper alloy contacts featuring gold plating, it ensures durability and low contact resistance. The unit employs a cantilever contact type and is intended for through-hole wire wrap termination.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 78-position dual row configuration and 0.100-inch pitch before ordering. Confirm compatibility with the target printed circuit board thickness range of 0.054 to 0.070 inches. Ensure the manufacturing source is authorized to guarantee compliance with RoHS3 standards and material specifications. Cross-reference the lead time requirements against project schedules as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a vertical, through-hole mounted connector with wire wrap termination is required. The 392 series offers a balance of density and mechanical strength suitable for general-purpose applications. Consider the black color coding and flangeless design if space constraints or specific panel mounting styles are factors. Validate that the operating temperature range of -40°C to 105°C meets environmental demands.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 392 series, which specializes in standard card edge solutions. The series is characterized by its use of thermoplastic polyester insulation and copper alloy contacts. It represents a legacy yet widely adopted form factor for connecting edge-mounted circuit cards to baseboards in various industrial and commercial electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations with different pin counts such as 392-026-540-201 or 392-056-542-102, provided the pitch and termination style remain compatible. Verify that any alternative maintains the dual female configuration and wire wrap termination capability.
