887-026-521-804

Edgeboard Connectors Overview

The EDAC Inc. 887-026-521-804 is a standard card edge connector receptacle from the 887 series, designed for high-temperature applications. It features 26 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch and a 5.08 mm row spacing. The component utilizes gold-plated copper alloy contacts and a black polyphenylene sulfide (PPS) insulator rated UL 94V-0. It supports a maximum operating temperature of +125°C and a minimum of -40°C, with a current rating of 3 A per contact.

Edgeboard Connectors Feature Summary

• High-temperature capability using PPS insulator material
• Gold-plated copper alloy contacts for reliable signal transmission
• Dual-row vertical mounting design for board edge insertion

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• Communication equipment interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific termination style and mounting ear configuration against the official datasheet before ordering, as the 887 series offers multiple variants including offset or flush ears and various pin lengths. Confirm that the dual-row receptacle matches the target PCB edge thickness of 1.57 mm to ensure proper mechanical fit and electrical engagement during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with a 3.96 mm pitch is required for high-temperature environments. The PPS housing provides superior thermal resistance compared to DAP materials found in other series. Ensure the application does not exceed the 3 A current rating per contact and verify that the vertical orientation aligns with the system's mechanical constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 887 series of high-temperature card edge connectors. The series is characterized by its use of polyphenylene sulfide (PPS) for the insulator, offering enhanced performance over standard materials. The 887 series provides various installation options and terminal styles to accommodate diverse panel and board mounting requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical 26-position dual-row configurations but different termination styles, such as 887-026-558-xxx variants. Cross-series replacement with the 837 series is possible if the pitch and position count match, though the insulator material will differ from PPS to DAP.
