306-009-420-178

Edgeboard Connectors Overview

The EDAC Inc. 306-009-420-178 is a standard card edge connector receptacle featuring dual female contacts with a 0.156-inch (3.96 mm) pitch. It provides 18 positions arranged in a single row, designed for through-hole mounting at a straight angle. The connector accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm). Contacts are copper alloy with a tin finish, rated for 5 A current. The insulator is green thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure board insertion
• Through-hole termination method for robust PCB attachment
• Accepts non-specified double-sided card edge boards

Edgeboard Connectors Applications

• Industrial control system interconnections
• Communication equipment backplanes
• Consumer electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating and body color specifications. Confirm that the required board thickness falls within the specified 1.37 mm to 1.78 mm range before finalizing procurement. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, single-row dual female connector is required for double-sided edge cards. Ensure the application environment remains within the -40°C to 105°C operating temperature limits. Verify that the 3.96 mm pitch aligns with the mating card edge layout and that through-hole assembly processes are compatible with the terminal design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which offers standard card edge connectors with 0.156-inch spacing. The series includes various position counts and mounting styles, providing versatile solutions for general-purpose electronic interconnects requiring reliable signal transmission across multiple industry sectors.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series ordering guide for alternative part numbers with different position counts or contact finishes. Direct substitutes must maintain the same 3.96 mm pitch and dual female configuration to ensure mechanical compatibility.
