306-021-421-158

Edgeboard Connectors Overview

The EDAC Inc. 306-021-421-158 is a dual female edgeboard connector designed for printed circuit board applications. It features 42 positions with a contact spacing of 0.156 inches (3.96 mm). The component utilizes a single centerline row configuration and accepts nominal PCB thicknesses of 0.062 inches (1.57 mm). Constructed with a low-profile insulator body, it provides reliable interconnection for edge-mounted cards.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card insertion
• Single centerline row design accommodating standard PCB thicknesses
• Low-profile insulator body for compact assembly requirements

Edgeboard Connectors Applications

• Edge-mounted circuit board interconnections
• Industrial control system backplanes
• Communication equipment card slots

Edgeboard Connectors Procurement Notes

Verify the specific part number against manufacturer documentation to ensure compatibility with required PCB thickness and contact spacing specifications. Confirm that the dual female configuration aligns with the mating card interface requirements. Cross-reference the low-profile body dimensions with available board space constraints before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual female edge connector with 0.156-inch spacing is required. Ensure the target application supports the nominal 0.062-inch PCB thickness acceptance. Evaluate the low-profile form factor against spatial limitations within the enclosure or chassis design to guarantee proper fit and mechanical stability during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of edgeboard connectors. The series offers various position counts and spacing options to suit different electronic assembly needs. The 306-021-421-158 variant specifically addresses applications requiring 42 positions with a wider 0.156-inch pitch, distinguishing it from finer-pitch alternatives in the product line.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified equivalent part numbers. Ensure any replacement maintains identical contact spacing, position count, and PCB thickness acceptance capabilities to preserve mechanical and electrical integrity within the existing assembly.
