306-012-421-178

Edgeboard Connectors Overview

The EDAC Inc. 306-012-421-178 is a standard card edge connector from the 306 series, designed for dual female termination with 24 positions arranged in two rows of 12. It features a 3.96 mm (0.156 inch) contact spacing and utilizes tin-plated copper alloy contacts with a solder pin termination type. The insulator body is constructed from thermoplastic polyester, providing a low-profile design that accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). This panel mount receptacle operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 306-012-421-178 with official EDAC documentation. Confirm RoHS compliance status and specific plating requirements against project specifications. Ensure mechanical compatibility with the target PCB thickness of 1.57 mm before procurement. Check for any regional distribution restrictions or supply limitations associated with this specific stock keeping unit.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 24-position interface with 3.96 mm spacing is required. It is suitable for applications demanding vertical panel mounting and robust thermal performance up to 105°C. Choose this model over single-row variants if higher density per width is needed. Ensure the mating card edge thickness falls within the specified 1.57 mm tolerance for reliable contact engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 Series, which specializes in standard card edge connectors featuring 3.96 mm contact spacing. The series offers various position counts and termination styles to accommodate diverse board layout requirements. The 306-012-421-178 specifically addresses needs for dual-sided connectivity with a compact form factor, fitting into broader industrial and commercial hardware architectures requiring reliable signal transmission.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 306-012-421-104 or 306-012-520-102, which share identical mechanical dimensions and positioning but may differ in contact plating materials such as gold versus tin. Verify that alternative part numbers maintain the same 24-position dual-row configuration and 3.96 mm pitch to ensure interchangeability without redesigning the host panel.
