306-017-420-158

Edgeboard Connectors Overview

The EDAC Inc. 306-017-420-158 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 34 positions with a 0.156-inch (3.96mm) contact spacing arranged in two rows of seven contacts per grid. The connector utilizes tin-plated tails for termination and gold plating on the mating area, supported by a copper alloy contact material. It accommodates PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The insulator is made of thermoplastic polyester, providing a green housing suitable for operation between -40°C and 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with non-specified card compatibility
• Gold-plated mating contacts with tin-plated termination tails
• Panel mount design with flange featuring top opening and threaded inserts

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct pin count, plating type, and flange configuration. Confirm that the target PCB thickness falls within the specified 0.054 to 0.070 inch range. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and order quantity.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 0.156-inch spacing is required for dual-sided card insertion. Ensure the application environment supports the -40°C to 105°C operating temperature range. Consider the panel mount installation method and verify that the available threading matches the assembly requirements. Compare against similar series parts if different contact spacings or insulation materials are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for robust mechanical performance. The series offers various position counts and spacing options to accommodate diverse board designs. The 306-017-420-158 specifically addresses applications requiring a 34-position interface with durable tin-plated tails for reliable soldering.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series cross-reference documentation for direct substitutes. Verify that any alternative part maintains identical 0.156-inch spacing, 34-position count, and dual-edge female configuration. Ensure mechanical dimensions and mounting hole patterns match the existing PCB layout to avoid redesign.
