306-021-520-168

Overview

The EDAC Inc. 306-021-520-168 is a standard card edge connector from the 306 series, designed for vertical panel mounting applications. It features a single row of 21 positions with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches), accommodating a range between 1.37 mm and 1.78 mm. Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The insulator body is constructed from thermoplastic material, providing durability in operating temperatures ranging from -40°C to +105°C.

Feature Summary

• Single centerline row configuration with .156 inch contact spacing
• Accepts .062 inch nominal thickness PCB cards
• Low profile insulator body design
• Gold-plated copper alloy contacts

Applications

• Vertical panel mount interconnects
• Standard card edge board connections
• Industrial control system interfaces
• Electronic equipment backplanes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count, termination style, and flange options. Ensure the selected variant matches the required PCB thickness tolerance and mounting hardware specifications. Cross-reference the RoHS compliance status and environmental ratings with the official product documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-row card edge interface with 3.96 mm pitch is required for vertical panel installation. Confirm that the target PCB thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm. Evaluate the need for gold-plated contacts for corrosion resistance and low contact resistance in the intended operational environment.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its .156 inch contact spacing and robust construction suitable for various electronic applications. The 306 series offers multiple variations in position count and termination styles, allowing for flexible integration into different board architectures and system designs.

Replacement Considerations

Direct substitutes must maintain the 3.96 mm pitch, single row configuration, and compatible PCB thickness range. Verify mechanical dimensions and mounting hole patterns to ensure physical compatibility. Electrical characteristics such as current rating and insulation resistance should match or exceed the original specifications.
