306-018-421-101

Edgeboard Connectors Overview

The EDAC Inc. 306-018-421-101 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 36 positions with a 0.156-inch (3.96mm) pitch and utilizes female contacts. The connector employs through-hole solder termination and tin-plated copper alloy contacts housed in a green thermoplastic polyester insulator. Rated for 5A current, it supports vertical panel mount installation and accommodates unspecified dual-edge cards.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Through-hole solder termination for robust PCB attachment
• Tin-plated copper alloy contacts for reliable signal transmission
• Vertical panel mount design for standardized enclosure integration

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics mainboard connections
• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and insulation color, as variations exist within the 306 series. Confirm that the tin finish meets environmental compliance requirements if lead-free standards are mandatory. Ensure the panel mount hole pattern matches the mechanical design specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96mm pitch is required. The tin-plated contacts offer a cost-effective solution compared to gold finishes while maintaining adequate conductivity. Verify that the 5A current rating aligns with the application's power distribution needs and that the vertical orientation fits the available chassis space constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of card edge connectors, which provides various termination styles and mounting options. The series includes variants with different contact counts, plating materials, and insulator colors. The 306-018-421-101 specifically denotes the 36-position dual-edge variant with tin plating and green housing, distinguishing it from other series members like the 302 or 896 lines.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position count but different plating or color codes. Cross-series replacements require matching the 3.96mm pitch and dual-edge form factor. Verify mechanical compatibility and electrical ratings before substituting with generic card edge connectors.
