305-080-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-080-556-203 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 80 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it ensures reliable signal transmission. The unit utilizes a low-profile insulator body made of thermoplastic polyester, colored green, and employs a solder termination type for secure PCB mounting.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact mechanical dimensions and plating specifications against project requirements. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status if environmental regulations apply to the assembly. Cross-reference the manufacturer datasheet for precise mating force and insulation resistance values before finalizing the bill of materials.

Edgeboard Connectors Selection Notes

Select this component when a high-density 80-position interface is required for dual-edge board connections. The 3.96 mm pitch accommodates standard board layouts while maintaining electrical isolation. Consider the vertical installation style and solder termination method for appropriate mechanical stability. Evaluate the operating temperature range and current ratings against the application's thermal and power demands.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and configurations to support diverse connectivity needs. The 305-080 variant specifically addresses applications requiring substantial I/O density within a constrained form factor, leveraging established industry-standard dimensions for interchangeability.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 80-position counts and 3.96 mm pitch, such as the 305-080-556-202 or 305-080-556-502, provided mechanical and electrical parameters align.
