306-021-420-102

Overview

The EDAC Inc. 306-021-420-102 is a standard card edge connector receptacle featuring 42 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for panel mount installation with vertical orientation. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission, supporting a current rating of 5 A. The housing is made of thermoplastic polyester, providing durability for industrial applications.

Feature Summary

• Dual-row female contact configuration for high-density interconnection
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic polyester insulator body for structural stability
• Vertical panel mount design for secure board retention

Applications

• Industrial control systems requiring robust card edge interfaces
• Electronic modules utilizing 1.57 mm thick printed circuit boards
• Panel-mounted equipment needing reliable vertical connectivity

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact plating, and mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-row female configuration matches the system requirements. Check RoHS compliance status if environmental regulations apply to the assembly. Validate that the 5 A current rating meets the electrical load demands of the application.

Selection Notes

Select this component when a dual-row interface with 3.96 mm spacing is required for 1.57 mm thick cards. The gold-plated contacts offer superior performance over tin-plated alternatives in corrosive environments. The vertical panel mount style simplifies assembly compared to surface-mount options. Consider the thermoplastic polyester housing for applications requiring high thermal stability. Ensure the 42-position count aligns with the signal routing needs of the design.

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 low-profile insulator bodies. These connectors are engineered for general-purpose electronic applications where reliable mechanical and electrical connections are critical. The 306 series offers various position counts and mounting styles to accommodate diverse design constraints.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with different position counts or mounting variations. Verify cross-compatibility with other manufacturers' connectors sharing identical 3.96 mm spacing and 1.57 mm board thickness specifications. Ensure any replacement maintains the dual-row female contact type and gold plating requirements.
