355-042-556-203

Edgeboard Connectors Overview

The EDAC Inc. 355-042-556-203 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 42 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated contacts and a black thermoplastic polyester insulator, supporting a temperature range of -40°C to 105°C. It accommodates card thicknesses between 0.054 and 0.070 inches and employs a straddle mount installation method with solder termination.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated semi-waffle spring contact type
• Straddle mount installation for secure board attachment
• Thermoplastic polyester insulation material

Edgeboard Connectors Applications

• Board extender applications
• Industrial control systems
• Communication equipment backplanes
• Consumer electronics assembly

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 355 Series Ordering Guide to ensure correct pin count, plating, and mounting style. Confirm that the target PCB or card thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with a 0.156-inch pitch is required for straddle mounting. Ensure the application demands a female connector for mating with male card edges. Consider the operating temperature range and contact material requirements before finalizing the design integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 355 series of standard card edge connectors. The series offers various position counts and mounting options. The 355-042 variant specifically provides 42 positions, balancing density and spacing for general-purpose interconnect needs in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 355 series parts with matching 42-position dual-edge specifications. Verify identical pitch, mounting type, and contact plating before substitution. Cross-reference with distributor databases for equivalent generic components meeting the same electrical and mechanical standards.
