306-019-521-101

Edgeboard Connectors Overview

The EDAC Inc. 306-019-521-101 is a dual-edge female card edge connector featuring 19 positions with a 0.156-inch (3.96mm) contact spacing. Designed for panel and through-hole mounting, it utilizes gold-plated cantilever contacts to ensure reliable signal transmission. The unit accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. Constructed with thermoplastic polyester insulation, the connector operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever spring contacts for secure board retention
• Gold-plated terminals provide corrosion resistance and low contact impedance
• Thermoplastic polyester insulator body ensures durability in demanding environments
• Panel mount design with flange features for stable mechanical installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment interface modules
• Automotive electronic control units
• Medical device internal circuitry connections

Edgeboard Connectors Procurement Notes

Verify that the replacement part matches the original 19-position count and 0.156-inch pitch exactly. Confirm the dual-edge female contact type aligns with the target PCB edge card specifications. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS3 compliance if restricted substances are prohibited in the supply chain.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for non-specified edge cards. The 0.156-inch spacing accommodates standard board layouts while providing ample clearance. The green color coding aids in visual identification during assembly. Consider the through-hole termination method for permanent, high-reliability soldering applications.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 series, which specializes in standard card edge solutions. The series offers various position counts and spacing options to suit different board densities. The 306-019 variant specifically addresses applications needing a compact 19-pin interface with high mechanical stability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series connectors with identical 19-position dual-edge female configurations. Verify that any alternative maintains the same 0.156-inch pitch and gold plating specification. Cross-reference flange dimensions to ensure compatibility with existing panel cutouts.
