305-072-500-503

Edgeboard Connectors Overview

The EDAC 305-072-500-503 is a standard card edge connector receptacle featuring 72 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for PCB mounting, it accepts boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure mating
• Low profile insulator body constructed from thermoplastic polyester
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Automotive electronics modules needing high current capacity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pin configuration and termination style. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the required polarizing key type matches the available options for this series. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row 72-position interface is required for .062 inch thick boards. The 5 A rating supports moderate power distribution needs. Verify that the straight mounting angle fits the enclosure constraints. Consider the 105°C maximum operating temperature for thermal management planning in enclosed environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. These connectors are designed for high-reliability applications where secure mechanical locking and electrical stability are critical for long-term performance.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-072-520-503 and 305-072-521-503 within the same series. Verify identical dimensional drawings and electrical ratings before substitution.
