306-029-521-158

Overview

The EDAC Inc. 306-029-521-158 is a dual-edge female card edge connector featuring 58 positions arranged in two rows of 29 contacts each. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The connector employs gold-plated cantilever spring contacts for reliable signal transmission and is housed in green thermoplastic polyester insulation. Designed for panel mounting via threaded inserts, it supports through-hole solder termination and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for secure board retention
• Panel mount design utilizing flush-mount flanges with top openings and 4-40 threaded inserts
• Gold-plated contact surfaces ensuring corrosion resistance and stable electrical performance
• Thermoplastic polyester insulator body providing structural integrity across specified thermal ranges

Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Test and measurement equipment needing high-density signal routing
• Telecommunications infrastructure utilizing standard card edge form factors
• Automotive electronics assemblies operating within defined thermal limits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to confirm exact pin count, contact plating thickness, and mounting hardware specifications. Ensure compatibility with target PCB thickness tolerances and panel cutout dimensions prior to procurement. Cross-reference the component status to confirm current availability and lead times directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when a high-pin-count dual-edge interface is required for panel-mounted applications. The 0.156-inch pitch accommodates larger trace widths compared to finer pitches, suitable for power or mixed-signal applications. Confirm that the 4-40 threaded insert mounting method aligns with the mechanical enclosure design and that the operating temperature range meets the environmental requirements of the end-use system.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors designed for general-purpose interconnect solutions. The series offers various position counts and mounting options, catering to diverse industrial and commercial electronic applications. The 306-029 variant specifically addresses needs for higher density connections while maintaining the durability associated with the series' cantilever contact technology.

Replacement Considerations

Consult the EDAC 306 Series cross-reference documentation for direct substitutes. Verify that alternative parts match the 0.156-inch pitch, 58-position count, dual-edge configuration, and panel mounting requirements to ensure mechanical and electrical compatibility.
