305-084-500-502

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-502 is a standard card edge connector from the 305 Series, designed for dual female contact configurations. It features a 3.96 mm (0.156 inch) pitch and accommodates 84 positions across two rows. The contacts are constructed from copper alloy with a gold finish of 10.0 µin (0.25 µm) thickness, utilizing semi-beam or eyelet termination types for soldering. The housing is made of green thermoplastic polyester, supporting panel mounting with vertical orientation. It operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with 84 total positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester insulation provides stability across a wide operating temperature range
• Panel mount design with vertical orientation facilitates secure board integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized connector pitches
• Test and measurement instrumentation boards
• Automotive electronics modules needing durable connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style, as the 305 series includes variations such as eyelets or half-beam contacts. Confirm the flange specifications align with the panel cutout dimensions, particularly regarding diameter and threadless top openings. Ensure the PCB thickness falls within the acceptable tolerance range for proper insertion force and retention. Cross-reference the RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for structural stability. The vertical panel mount style suits applications where space constraints favor direct board-to-panel connections over cable harnesses. Consider the gold contact finish for environments demanding long-term reliability against oxidation. Evaluate the thermal rating to ensure compatibility with the operational heat profile of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting options. The series is characterized by its standardized 3.96 mm pitch and dual-row availability. Similar parts in the lineup include different pin counts like 305-044-500-502 or 305-050-556-502, sharing common electrical and mechanical traits while differing in size and specific termination details.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series require matching the 84-position count and 3.96 mm pitch. Verify that alternative part numbers maintain the same dual female contact type and gold plating specification. Ensure the replacement supports the same panel mount orientation and vertical installation angle to fit existing mechanical enclosures without modification.
