837-031-521-101

Edgeboard Connectors Overview

The EDAC Inc. 837-031-521-101 is a single-edge female card edge connector from the 837 High Temp series, designed for through-hole mounting. It features 31 positions with a 0.156-inch (3.96mm) contact spacing and utilizes copper alloy contacts with a gold finish of 10.0µin (0.25µm). The connector supports PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 125°C. Constructed with DAP insulation, it includes flange features for flush mounting with threaded inserts.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm termination type and flange configuration. Ensure compatibility with target PCB thickness and hole patterns. Confirm RoHS compliance status if required by project specifications. Cross-reference the full part number to avoid confusion with similar variants in the 837 series that may differ in contact count or mounting style.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 31-position connection is needed with high thermal tolerance. The 0.156-inch pitch accommodates standard board layouts while providing robust mechanical retention. Consider the through-hole solder termination for secure attachment. Evaluate the operating temperature range against environmental conditions to ensure performance integrity under stress.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 837 High Temperature Series, which is engineered for superior performance in harsh conditions compared to standard connectors. The series offers various pin counts and termination options, all sharing common high-reliability characteristics such as gold plating and durable insulation materials designed for long-term stability.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for direct replacements. Verify that any alternative maintains the same 31-position count, 0.156-inch pitch, and high-temperature rating. Ensure mechanical dimensions and flange features match the existing design to prevent assembly issues.
