306-031-400-104

Overview

The EDAC Inc. model 306-031-400-104 is a standard card edge connector receptacle featuring 31 positions in a single central row with a 3.96 mm pitch. It utilizes copper alloy contacts with tin plating and supports a current rating of 5 A. Designed for panel mount installation, the housing is constructed from green thermoplastic polyester. The connector accommodates board thicknesses within the range of 1.37 mm to 1.78 mm and operates reliably between -40°C and 105°C.

Feature Summary

• Single central row configuration for dual-edge card insertion
• Thermoplastic polyester housing providing structural stability
• Tin-plated copper alloy contacts ensuring reliable signal transmission
• Panel mount design with vertical orientation

Applications

• Industrial control systems requiring robust interconnects
• Medical equipment utilizing standardized card edge modules
• Aerospace and defense electronic assemblies
• Computing and storage hardware backplanes

Procurement Notes

Verify the specific contact count and row configuration against the official datasheet before procurement. Confirm that the tin plating specification meets the environmental requirements of the target application. Ensure the panel mounting style aligns with the mechanical design constraints. Cross-reference the operating temperature range with the system's thermal profile to guarantee long-term reliability under all expected conditions.

Selection Notes

Select this component when a single-row, 31-position interface is required with a 3.96 mm spacing. The tin-plated contacts are suitable for general-purpose applications where gold plating is not strictly necessary. Consider the vertical panel mount form factor for integration into enclosed chassis designs. Evaluate the 5 A current rating against the maximum load requirements of the connected circuitry to ensure safe operation.

Part Context

This part belongs to the EDAC 306 Series, which provides a wide range of card edge connectors for rack and panel applications. The series is designed for computing, storage, medical, aerospace, industrial, communications, consumer, and clean technology sectors. EDAC focuses on delivering high-quality interconnect solutions with rigorous quality assurance standards.

Replacement Considerations

Compatible substitutes include other EDAC 306 series variants with matching position counts and pitch specifications. Verify that alternative parts maintain the same single-row configuration and panel mount orientation. Ensure that the replacement connector supports the same board thickness range and current rating to preserve electrical and mechanical integrity.
