306-026-521-108

Overview

The EDAC Inc. 306-026-521-108 is a standard card edge connector from the 306 Series, designed for dual female mating with edgeboards. It features a contact spacing of 0.156 inches (3.96mm) and provides 26 positions across two rows, totaling 52 contacts. The connector utilizes PC tail termination type with gold plating on the contact area to ensure reliable signal transmission. The housing material is thermoplastic, offering durability for industrial applications. This component supports vertical mounting styles and is engineered to withstand operating temperatures up to +105°C, making it suitable for environments requiring moderate thermal resilience.

Feature Summary

• Dual female configuration providing 52 total contact positions for robust board-to-board connectivity
• Gold-plated PC tail contacts ensure low resistance and corrosion-resistant performance
• Thermoplastic housing material offers structural integrity and chemical resistance
• Vertical mounting design facilitates efficient PCB layout and assembly processes

Applications

• Industrial control systems requiring reliable interconnects
• Telecommunications equipment infrastructure
• Medical device internal circuitry connections
• Consumer electronics manufacturing assemblies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and plating thickness. Ensure the target PCB design accommodates the 0.156-inch pitch and dual-row formation. Confirm that the thermoplastic housing material meets the thermal requirements of the intended application environment before finalizing procurement orders.

Selection Notes

Select this model when a dual-row card edge connector with 52 contacts is required for vertical PCB integration. The 0.156-inch pitch allows for higher density compared to larger spacing options while maintaining reliable electrical isolation. Consider the gold plating for applications demanding long-term reliability in corrosive environments. Verify that the maximum operating temperature of +105°C aligns with the system's thermal profile.

Part Context

This component belongs to the EDAC 306 Series, which specializes in standard card edge connectors for various electronic industries. The series is known for providing versatile interconnect solutions across communication, medical, and industrial sectors. The 306-026-521-108 variant specifically addresses needs for medium-density connections with durable thermoplastic construction and reliable gold-plated termination methods.

Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers within the 306 Series or compatible families. Ensure any replacement maintains the same 0.156-inch pitch, 52-position count, and dual female configuration. Verify that mechanical dimensions and termination types match the existing PCB footprint to prevent assembly issues.
