305-012-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-503 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 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating and a thermoplastic polyester insulator, it supports a current rating of 5 A. The unit operates within a temperature range of -40°C to +105°C and includes flange features for flush mounting.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration for your PCB layout. Confirm that the board thickness falls within the specified acceptance range to ensure proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 regulations if required for your assembly process. Cross-reference the flange dimensions against your chassis mounting requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 12-position connection is required with a 3.96 mm pitch. It is suitable for applications demanding panel mounting rather than direct PCB soldering. Consider the 5 A current rating and operating temperature range against your system's thermal and electrical loads. Verify compatibility with the target PCB thickness before finalizing the design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various configurations of standard card edge connectors. The series is characterized by its robust construction and standardized spacing, making it a common choice for modular electronic systems requiring reliable high-density connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-014-555-503 or 305-012-521-202, depending on whether single or double row configurations are needed. Always verify that any replacement maintains the identical 3.96 mm pitch and 1.57 mm board thickness tolerance.
