305-028-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-502 is a dual-edge female card edge connector designed for board-to-board applications. It features 28 positions with a 0.156-inch (3.96mm) spacing across two rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. It supports solder termination and accommodates card thicknesses between 0.054 and 0.070 inches. Rated for 5A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts both between-contact and in-contact polarizing keys for secure alignment
• Provides reliable electrical connection through gold-plated half-bead contact design
• Features a robust thermoplastic polyester insulator for environmental stability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct pin count, plating thickness, and mounting style. Confirm that the target PCB stack-up aligns with the specified card thickness tolerance. Check RoHS3 compliance status if required by project specifications. Ensure the selected variant matches the intended panel or board edge mounting configuration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with 28 positions is required. Verify compatibility with the mating card's thickness range of 1.37mm to 1.78mm. Consider the 0.156-inch pitch for trace routing constraints. Evaluate the 5A current rating against the application's power distribution needs. Confirm that the operating temperature range meets the environmental requirements of the deployment site.

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 305-028-555-502 specifically addresses applications requiring a moderate density dual-edge connection with high current capability. It complements other variants in the lineup that differ primarily in terminal count and physical dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical mechanical footprints but different pin counts, such as the 305-028-555-508. Cross-series replacements require verification of pitch, height, and locking mechanism compatibility. Always validate electrical ratings and thermal performance before substituting.
