887-050-544-212

Edgeboard Connectors Overview

The EDAC Inc. 887-050-544-212 is a dual-edge female card edge connector from the 887 series, designed for high-temperature applications. It features 50 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch and a 0.200-inch (5.08 mm) row spacing. The housing is constructed from black Polyphenylene Sulfide (PPS), UL 94V-0 rated, accommodating a board thickness of 0.062 inches (1.57 mm). Contacts are copper alloy with gold plating over nickel, rated for 3 A current and 1800 V AC rms dielectric strength. The unit operates within a temperature range of -40°C to +125°C.

Edgeboard Connectors Procurement Notes

Verify the exact part number against official EDAC documentation to confirm compatibility with your specific PCB design requirements. Ensure that the dual-edge configuration matches your board layout. Check for any recent updates to the datasheet regarding mechanical tolerances or material specifications. Confirm that the supplier provides genuine EDAC products to guarantee performance standards. Review installation guidelines for proper insertion force and retention characteristics before integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for high-temperature environments. The 0.156-inch pitch suits applications needing wider spacing between contacts. Consider the 50-position count for moderate density needs. Verify that the board thickness aligns with the specified 0.062-inch requirement. Evaluate if the PPS material properties meet your chemical and thermal resistance criteria compared to other series options.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 887 series, which specializes in high-temperature card edge solutions. The series offers various row counts, pin configurations, and mounting options. The 887 series distinguishes itself through the use of PPS insulation, providing superior heat resistance compared to lower-temperature alternatives. It is part of a broader portfolio designed for industrial and commercial electronic interconnects.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations in position count or tail style, such as 887-050-544-202 or 887-050-544-802. Ensure any replacement maintains the dual-edge female configuration and identical pitch. Verify that the insulator material and temperature rating remain consistent. Cross-reference mechanical drawings to confirm panel mount compatibility and slot depth alignment.
