306-026-421-158

Overview

The EDAC Inc. 306-026-421-158 is a dual female card edge connector designed for panel and through-hole mounting. It features 52 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes tin-plated cantilever contacts and a green thermoplastic insulator. It supports PCB thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female configuration with cantilever contact type for reliable board insertion
• Flush mount flange design with top opening and threaded inserts for secure panel installation
• Tin-plated copper alloy contacts ensuring corrosion resistance and conductivity
• Green thermoplastic polyester insulator providing structural stability

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces
• Medical device circuit board connections

Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style, as variations exist within the series. Ensure the selected part number matches the required PCB thickness and mounting hole specifications. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer drawing for precise mechanical dimensions before integration.

Selection Notes

Select this component when a dual-row female interface with 0.156-inch spacing is required. Consider the flush mount feature for applications needing a low-profile connection point. Evaluate the operating temperature range against the environmental conditions of the target application. Verify that the PCB stack-up accommodates the specified card thickness limits for proper engagement.

Part Context

This connector belongs to the EDAC 306 Series, which provides standard card edge solutions. The series offers various pin counts and spacing options to suit different density requirements. Components in this line are designed for robust performance in general-purpose electronic assemblies. The model number encodes specific attributes such as position count and contact finish.

Replacement Considerations

Compatible substitutes include other EDAC 306 series connectors with matching 52-position dual female configurations. Verify that alternative parts maintain the same 0.156-inch pitch and flush mount flange geometry. Ensure electrical ratings and material composition align with the original design specifications.
