306-027-400-168

Overview

The EDAC Inc. 306-027-400-168 is a standard card edge connector featuring 54 positions in a single row with a 3.96 mm (0.156 inch) contact spacing. It utilizes tin-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Designed for panel mount installation, this vertical header includes integrated card guides to facilitate repeatable insertion. The insulator body is constructed from thermoplastic material, providing a low-profile form factor suitable for space-constrained applications.

Feature Summary

• Incorporates card guides to ensure precise alignment and repeatable board insertion
• Features a low-profile insulator body for compact panel mounting
• Utilizes tin-plated contacts on a copper alloy substrate for reliable conductivity

Applications

• Serviceable electronic assemblies requiring frequent maintenance access
• Panel-mounted interface connections for industrial control systems
• Vertical interconnects for double-sided card edge PCBs

Procurement Notes

Verify the specific ordering suffix to confirm contact plating and insulation color, as these attributes vary within the 306 series. Confirm that the target application supports the 3.96 mm pitch and 1.57 mm board thickness requirements. Ensure compatibility with the required panel cutout dimensions and mounting hardware specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-row, vertically mounted card edge connector with built-in guiding features is required. The 3.96 mm pitch accommodates standard thick PCBs, while the tin plating offers a cost-effective solution compared to gold finishes. Consider the panel-mount style if the connector must be secured directly to an enclosure rather than the circuit board itself.

Part Context

This part belongs to the EDAC 306 Series of standard card edge connectors. The series provides various position counts and mounting styles, including panel and board mount options. The 306-027 variant specifically denotes a 27-position configuration per side or 54 total positions, distinguishing it from other series like the 302 or 387 which offer different pitches or row configurations.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other EDAC 306-series parts with matching 3.96 mm pitch and 54 positions. Verify mechanical fit and electrical ratings against alternative manufacturers' card edge headers with similar guide-integrated designs.
