305-012-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-012-556-503 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 12 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and supports a maximum board thickness of 1.57 mm. Contact plating is gold over copper alloy, ensuring reliable signal transmission. The unit employs solder pin termination for secure PCB attachment and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided circuit boards
• Panel mount installation style provides stable mechanical support
• Gold-plated contacts ensure corrosion resistance and conductivity
• Vertical orientation facilitates direct board insertion

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane integration
• Test and measurement instrument module mounting
• Embedded computing system expansion slots

Edgeboard Connectors Procurement Notes

Verify that the target application requires a 0.156 inch pitch rather than the more common 0.100 inch variant found in other EDAC series. Confirm the specific row count and position quantity match the design requirements before ordering. Ensure the solder pin termination type aligns with the assembly process capabilities. Check for any specific RoHS compliance documentation if required by the end product regulations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 12-position connection is necessary for thicker PCBs up to 1.57 mm. The 305 series offers robust panel mounting compared to surface mount alternatives. Consider the vertical orientation for space-constrained enclosures where front-access is needed. Compare against the 395 series if a smaller 0.100 inch pitch is acceptable for the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their larger 0.156 inch pitch. This series distinguishes itself from the 395 series, which uses a finer 0.100 inch pitch. The 305 series is engineered for high-reliability applications requiring durable panel-mount solutions with substantial mechanical stability for heavy-duty industrial environments.

Edgeboard Connectors Replacement Considerations

The EDAC 395-012-556-503 serves as a potential substitute but utilizes a different 0.100 inch pitch, requiring PCB layout modifications. Other generic card edge connectors must be evaluated for matching pitch, row count, and mounting style compatibility.
