306-009-421-103

Edgeboard Connectors Overview

The EDAC Inc. 306-009-421-103 is a standard card edge connector receptacle designed for dual-edge board applications. It features 18 positions with a 3.96 mm (0.156 inch) pitch. The unit utilizes tin-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it supports panel mount installation at a vertical angle. The connector accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Thermoplastic polyester insulation for thermal stability
• Panel mount design with vertical orientation
• Tin-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, housing color, and mounting style variations. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical engagement. Confirm RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. Consider the 5 A current rating and 105°C maximum operating temperature for environmental suitability. Verify that the panel mount vertical style aligns with the chassis design constraints and that the tin-plated contacts meet the corrosion resistance requirements of the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination options. The 306-009-421-103 specifically addresses dual-edge applications, distinguishing it from single-edge variants in the same family. It provides a standardized solution for modular electronic systems requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 306 series parts sharing the 3.96 mm pitch and 18-position count. Verify identical dual-edge configuration and panel mount vertical orientation before substitution. Ensure compatible PCB thickness tolerance and current ratings match the original design requirements.
