305-042-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-204 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 42 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission. The insulator body is made of thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct flange and termination specifications. Confirm that the required board thickness aligns with the 1.57 mm nominal tolerance. Check RoHS compliance status if restricted substances are prohibited in your assembly process. Ensure the vertical mounting style matches the mechanical constraints of the target enclosure design before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 42 positions is required for vertical installation. The 3.96 mm pitch accommodates standard double-sided PCB layouts. Consider the gold plating thickness if long-term wear resistance is critical. Evaluate the thermal performance within the -40°C to +105°C range to ensure compatibility with the operational environment of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and mounting styles to support diverse design requirements. The 305-042 variant specifically addresses applications needing moderate pin density with secure panel mounting capabilities.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series base code but differing in position count or flange style. Verify mechanical footprint compatibility before substituting with other manufacturers' equivalents. Ensure electrical ratings and material compositions match the original design specifications.
