837-084-559-802

Edgeboard Connectors Overview

The EDAC Inc. part number 837-084-559-802 is a high-temperature card edge connector from the 837 series. It features 84 positions in a dual female configuration with a 0.156-inch (3.96mm) contact spacing. The connector utilizes wire wrap termination and gold-plated cantilever contacts housed in a green diallyl phthalate (DAP) insulator. Designed for through-hole mounting, it supports board thicknesses typically ranging from 0.054 to 0.070 inches. The unit operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 837/887 Series Ordering Guide to ensure correct pin count, termination style, and plating specifications. Confirm that the target application environment remains within the specified -40°C to 125°C operating range. Check for compliance with current RoHS3 and REACH regulations as documented in the manufacturer's environmental classification data.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-sided connection is required for thick circuit boards. The 0.156-inch pitch suits applications where mechanical robustness and high-temperature performance are prioritized over miniaturization. Ensure the mating card edge thickness falls within the connector's acceptance range to maintain proper contact force and electrical continuity during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 837 series, which specializes in high-temperature card edge connectors. The series is characterized by its use of durable diallyl phthalate insulation and gold-plated contacts designed for harsh environments. The 837 series offers various position counts and configurations to support diverse industrial and military electronic interconnection needs.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 837/887 Series Ordering Guide for direct substitutes. Verify that any alternative maintains identical 84-position dual-edge geometry, 0.156-inch pitch, and wire wrap termination compatibility to ensure mechanical fit and electrical performance equivalence.
