306-028-420-108

Overview

The EDAC Inc. 306-028-420-108 is a standard card edge connector receptacle designed for panel mount applications. It features a dual female configuration with 56 positions arranged in two rows, providing a contact spacing of 0.156 inches (3.96 mm). The unit utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual row female contact configuration for high-density interconnection
• Panel mount installation style with flush mounting flange
• Tin-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator housing for durability

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB form factors
• Test and measurement instrumentation panels
• Consumer electronics manufacturing assembly lines

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required plating and housing color specifications. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical retention and electrical contact. Check regional availability as distribution status may vary by location.

Selection Notes

Select this component when a dual-row, 56-position interface is required for vertical panel mounting. Ensure the application environment remains within the -40°C to 105°C operational temperature limits. Consider the tin plating option if lead-free compliance is necessary, noting that gold plating options exist in other series variants for different conductivity requirements.

Part Context

This part belongs to the EDAC 306 Series, which represents a line of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, catering to general-purpose electronic interconnection needs across various industrial and commercial sectors.

Replacement Considerations

Compatible substitutes include EDAC 306-023-421-102 and 306-010-421-108, provided the position count and pitch match the design requirements. Verify that alternative parts maintain the same dual-row configuration and panel mount orientation.
