305-082-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-082-500-203 is a standard card edge connector featuring 82 positions with a 2.54 mm pitch. It is designed for double-sided card edges and utilizes gold-plated copper alloy contacts. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms. This panel-mount receptacle accepts printed circuit boards with a nominal thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Accepts double-sided card edges with a nominal board thickness of 1.57 mm
• Features gold-plated copper alloy contacts for reliable signal transmission
• Constructed with a thermoplastic polyester insulator body

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific pin count and pitch configuration against the official datasheet before procurement. Confirm that the target application requires a 2.54 mm pitch rather than the more common 3.96 mm variant found in other series members. Ensure panel mounting compatibility and thermal requirements align with the specified operating temperature range.

Edgeboard Connectors Selection Notes

Select this component when a high-contact-count interface is required for double-sided PCBs. The 2.54 mm pitch offers higher density compared to the 3.96 mm series. Verify that the mating card thickness falls within the acceptable tolerance for the 1.57 mm nominal specification to ensure proper mechanical engagement and electrical contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. While many parts in this series utilize a 3.96 mm pitch, this specific model is distinguished by its 2.54 mm spacing. It shares the same general form factor and material specifications as other series members but provides a different density profile for specialized applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include the 345-082-500-203, which shares identical positioning and pitch characteristics. When replacing, verify that the alternative component maintains the same panel mount style and current rating to ensure functional equivalence.
