306-009-421-178

Edgeboard Connectors Overview

The EDAC Inc. model 306-009-421-178 is a standard card edge connector receptacle featuring 18 positions arranged in a single row. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs female, straight mounting with through-hole solder termination. Contacts are constructed from copper alloy with a tin plating finish, rated for 5 A current. The insulator body is made of green thermoplastic polyester, providing a low-profile design suitable for panel installation.

Edgeboard Connectors Feature Summary

• Accepts PCBs with a nominal thickness of 0.062 inches (1.57 mm)
• Features a low-profile insulator body for compact integration
• Utilizes a single centerline row configuration for straightforward routing

Edgeboard Connectors Applications

• Industrial control systems requiring reliable board-to-board connections
• Communication equipment utilizing standard card edge interfaces
• Consumer electronics assemblies needing durable through-hole connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal plating and contact material specifications. Ensure the target application supports the 0.156-inch pitch and single-row layout. Confirm that the PCB thickness aligns with the 0.062-inch nominal requirement for proper mechanical retention. Check RoHS compliance status against current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a single-row, through-hole card edge connector is required. The 0.156-inch pitch accommodates standard board designs. Tin-plated contacts offer cost-effective conductivity for general-purpose applications. The green thermoplastic polyester housing provides necessary insulation properties. Verify that the straight mounting style fits the enclosure constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting options. The 306 series is designed for robust performance in industrial and commercial environments. Components in this family typically feature thermoplastic polyester insulators and copper alloy contacts.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 306 series parts for different position counts. Verify compatibility with existing PCB footprints before substitution. Ensure that any alternative maintains the same 0.156-inch pitch and through-hole termination style.
