842-007-521-103

Edgeboard Connectors Overview

The EDAC Inc. 842-007-521-103 is a standard card edge connector receptacle designed for single-edge board applications. It features seven positions with a 2.54 mm (0.100 inch) pitch and supports PCB thicknesses ranging from 1.37 mm to 1.78 mm. The component utilizes gold-plated copper alloy contacts housed in a green diallyl phthalate insulator rated UL 94V-0. It employs a right-angle through-hole mounting style, ensuring secure mechanical attachment and reliable electrical connectivity for high-temperature environments.

Edgeboard Connectors Feature Summary

• Single-edge female connector configuration for standardized card insertion
• Gold-plated copper alloy contacts ensure durable conductivity
• Right-angle through-hole mounting facilitates precise PCB alignment
• Diallyl phthalate insulator provides thermal stability and UL 94V-0 rating

Edgeboard Connectors Applications

• High-temperature industrial control systems
• Medical interconnect solutions requiring reliable signal transmission
• Agricultural technology equipment operating in harsh environments
• General-purpose electronic assemblies needing robust card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating, insulator color, and mounting orientation match project requirements. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper engagement. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a right-angle, single-edge connection is required for boards up to 1.78 mm thick. The 2.54 mm pitch suits standard digital or analog signal routing. Consider the high-temperature capability of the diallyl phthalate material if the application exceeds standard operating ranges. Verify that the through-hole footprint aligns with the manufacturing capabilities of the assembly line.

Edgeboard Connectors Part Context

This part belongs to the EDAC 842 series, which specializes in high-temperature card edge connectors. The series is engineered for durability in demanding sectors such as medical and agricultural technologies. The 842 series distinguishes itself by using diallyl phthalate insulation, offering superior thermal performance compared to standard thermoplastics, making it suitable for elevated temperature operational scenarios.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 842 family for variations in position count or mounting style. Verify that any substitute maintains the 2.54 mm pitch and single-edge configuration. Ensure the replacement part matches the right-angle orientation and through-hole termination method to preserve mechanical fit and electrical interface integrity.
