306-016-400-178

Edgeboard Connectors Overview

The EDAC Inc. 306-016-400-178 is a standard card edge connector from the 306 series, designed for through-hole mounting. It features a dual female configuration with 32 total positions arranged in two rows of 16. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are tin-plated copper alloy, providing reliable electrical connection. The insulator body is constructed from green thermoplastic polyester, ensuring durability and stability in various industrial environments.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodates non-specified double-sided PCBs
• Low-profile insulator body reduces overall assembly height
• Flange features include flush mount capability with top opening
• Integrated card guides ensure precise board insertion alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Communication equipment backplanes
• Consumer electronic device interconnects
• Medical instrumentation circuit boards

Edgeboard Connectors Procurement Notes

Verify that the required PCB thickness aligns with the 0.062-inch nominal specification to ensure proper mechanical retention. Confirm that the tin plating finish meets the environmental and conductivity requirements for the specific application, as this differs from gold-plated variants in the same series. Ensure the mounting style matches the target board layout.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge connector with tin plating is required for 3.96 mm pitch applications. The 306 series offers a balance of mechanical strength and electrical performance. Consider the flange characteristics for panel mounting needs. Compare against gold-plated versions if higher corrosion resistance or lower contact resistance is critical for the signal integrity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in general-purpose electronic assemblies. The series provides various position counts and plating options. The 306-016-400-178 specifically addresses the need for a 16-position per side connector with a durable tin finish, suitable for high-volume manufacturing where cost-effectiveness and reliability are prioritized over premium surface finishes.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 306 series include parts with identical pin counts but different plating, such as 306-016-520-178 (gold plated). Verify that any replacement maintains the same 3.96 mm pitch and 1.57 mm board thickness compatibility. Cross-reference with other EDAC series like 316 or 356 only if form factor changes are acceptable.
