306-019-521-168

Overview

The EDAC Inc. 306-019-521-168 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 38 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes gold-plated cantilever contacts on a green thermoplastic polyester insulator, supporting PCB thicknesses from 0.054 to 0.070 inches. Operating within a temperature range of -40°C to 105°C, it includes flange features for flush installation with top openings and 4-40 threaded inserts.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable board insertion
• Green thermoplastic polyester insulator body rated for high-temperature environments
• Panel mount design with integrated flange featuring top openings and threaded inserts

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module connections

Procurement Notes

Verify the specific pin count and contact spacing against the target PCB layout before ordering. Confirm that the mounting hole pattern matches the 4-40 threaded insert specifications. Ensure the selected PCB thickness falls within the 0.054 to 0.070 inch operational range. Check for RoHS compliance requirements if operating in restricted jurisdictions.

Selection Notes

Select this component when a robust dual-edge interface with wide contact spacing is required. The 0.156-inch pitch accommodates larger traces compared to finer pitches. Consider the through-hole termination method for superior mechanical stability. Evaluate the thermal rating if the application involves significant heat generation during operation.

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 306-019 variant specifically provides 38 contacts, balancing density with ease of assembly. It is distinct from single-row or different pitch variants within the broader product line.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with identical 38-position dual-edge configurations. Verify compatibility with existing PCB footprints and mounting hardware. Cross-reference with generic industrial connectors only if pinout and mechanical dimensions match exactly.
