887-031-544-603

Edgeboard Connectors Overview

The EDAC Inc. 887-031-544-603 is a high-temperature standard card edge connector receptacle designed for vertical panel mount applications. It features 31 positions with a single row configuration and a contact spacing of 3.96 mm (0.156 inches). The unit utilizes gold-plated copper alloy contacts terminated via solder pins, ensuring reliable electrical performance. Constructed with a polyphenylene sulfide (PPS) insulator body rated UL 94V-0, it supports a nominal printed circuit board thickness of 1.57 mm (0.062 inches). The component operates within a temperature range of -40°C to +125°C, offering an insulation resistance of 5 GOhms minimum and a current rating of 3 A per contact.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm terminal style, mounting ear configuration, and insulator type. Ensure the selected variant matches the required PCB thickness and panel cutout dimensions. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a single-row, 31-position connection is required for thick PCBs in high-heat environments. Compare against the broader 887 series options to determine if alternative row counts or termination styles better suit the mechanical constraints. Validate that the 3.96 mm pitch aligns with the mating card edge design specifications.

Edgeboard Connectors Part Context

This component belongs to the EDAC 887 series of high-temperature card edge connectors. The series is characterized by robust construction using PPS materials and versatile mounting options. It serves as a specialized solution for demanding applications where standard connectors may fail due to thermal stress or mechanical vibration.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 887 series cross-reference guide for direct substitutes. Verify that any replacement part maintains identical 31-position count, 3.96 mm pitch, and vertical panel mount orientation to ensure mechanical compatibility.
