306-020-421-158

Edgeboard Connectors Overview

The EDAC Inc. 306-020-421-158 is a standard card edge connector featuring 20 positions arranged in a single centerline row with a 0.156-inch (3.96mm) contact spacing. Designed for panel installation, it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component utilizes copper alloy contacts with gold plating and a thermoplastic insulator body. It operates within a temperature range of -40°C to +105°C and carries RoHS3 compliance.

Edgeboard Connectors Feature Summary

• Single centerline row configuration for simplified board layout
• Accepts nominal 0.062 inch thick PCBs for standard compatibility
• Low profile insulator body design for space-constrained applications

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Standard card edge interface modules
• Industrial control board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct termination style and contact plating specifications. Confirm that the required PCB thickness aligns with the 0.062-inch nominal acceptance range. Check for updated environmental compliance documentation such as RoHS3 status prior to final procurement approval.

Edgeboard Connectors Selection Notes

Select this component when a single-row card edge connector with wide 0.156-inch spacing is required. Ensure the application environment stays within the specified -40°C to +105°C operating temperature range. Verify that the panel mounting style matches the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various position counts and spacing options, typically utilizing thermoplastic insulators and gold-plated copper alloy contacts. These components are designed for reliable vertical or panel-mount connections in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 306 series variants sharing the same 0.156-inch pitch and single-row configuration. Verify mechanical footprint compatibility and electrical rating equivalence before substituting with alternative manufacturers' products.
