305-072-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-072-500-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 72 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The unit provides an insulation resistance of 5 GOhms and accommodates PCB thicknesses up to 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing
• Gold-plated contacts ensure reliable conductivity
• Thermoplastic polyester housing for thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and flange specifications. Ensure compatibility with target PCB thickness limits before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel mounting style and orientation for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-edge interface is required with a 3.96 mm pitch. Consider the 5 A current rating and operating temperature range for environmental suitability. Evaluate the vertical or straight mounting options based on chassis constraints. Compare against alternative series if different contact types or housing materials are needed for specific chemical resistance requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-072-500-203 specifically addresses high-pin-count applications. It is distinct from single-row variants and different series like the 315 or 355 which may offer different mechanical profiles or contact configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pin counts and pitch, such as 305-072-520-203, provided mechanical fitment matches. Cross-brand replacements require verification of pitch, row count, and current ratings. Ensure any substitute maintains the same insulation resistance and temperature performance characteristics.
