305-062-555-203

Edgeboard Connectors Overview

The EDAC 305-062-555-203 is a standard card edge connector receptacle featuring 62 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch with gold-plated copper alloy contacts and solder termination. Designed for PCB mounting, the unit accommodates a board thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing an insulation resistance of 5 GOhms and a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-row design facilitates high-density signal routing
• High-temperature insulator construction ensures stability under thermal stress

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement instrumentation with high pin count requirements

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required contact count and row configuration before ordering. Confirm that the mating card edge thickness aligns with the specified 1.57 mm tolerance to ensure proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS directives if applicable to the assembly environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is necessary for high-pin-count applications. Consider the 5 A current rating and 105°C maximum operating temperature for environments with elevated thermal loads. Evaluate the need for polarizing key compatibility if precise orientation during insertion is critical for the system design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility and reliability. The series offers various position counts and termination options to support diverse electronic packaging needs. The 305-062-555-203 specifically addresses applications requiring a 62-position dual-row connection with solder tail termination.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as the 305-062-555-204 or 305-062-500-203. Verify that any replacement maintains the 3.96 mm pitch and dual-row layout to ensure mechanical and electrical compatibility with existing PCB footprints.
