306-031-421-158

Overview

The EDAC Inc. 306-031-421-158 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 31 positions with a 0.156-inch (3.96mm) contact spacing and accepts PCBs with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes female contacts with tin plating and a low-profile insulator body. It supports panel mount installation via tails and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Accepts printed circuit boards with a nominal thickness of 0.062 inches
• Features a low-profile insulator body design
• Utilizes single centerline row configuration with tin-plated contacts

Applications

• Industrial control systems requiring robust card edge connections
• Communication equipment interface modules
• Consumer electronic device internal interconnects

Procurement Notes

Verify the specific pin count and contact spacing against the target PCB design before procurement. Confirm that the tin plating specification meets the environmental requirements for the intended application. Ensure the panel mounting method aligns with the mechanical constraints of the assembly. Check for RoHS compliance status if restricted substances are prohibited in the final product.

Selection Notes

Select this component when a 0.156-inch pitch is required for dual-edge card applications. Consider the low-profile form factor if vertical space is limited. Evaluate the tin-plated contacts for cost-effectiveness compared to gold-plated alternatives. Ensure the operating temperature range of -40°C to 105°C suits the environmental conditions of the deployment site.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors with 0.156-inch spacing. The series offers various position counts and termination styles to accommodate diverse board layouts. The 306 series is widely used in general-purpose electronics where reliable mechanical and electrical connections are necessary for modular designs.

Replacement Considerations

Direct substitutes within the same series include parts with identical 0.156-inch spacing and compatible PCB thickness specifications. Verify that any replacement maintains the same terminal type and mounting style to ensure mechanical compatibility.
