837-042-544-108

Edgeboard Connectors Overview

The EDAC Inc. 837-042-544-108 is a high-temperature card edge connector from the 837 Series, designed for vertical through-hole mounting. It features 42 positions with a 0.156-inch (3.96 mm) contact spacing and utilizes wire wrap termination. The connector employs copper alloy cantilever contacts with a gold plating thickness of 10.0 µin (0.25 µm). Constructed with green diallyl phthalate (DAP) insulation, it supports PCB thicknesses ranging from 0.054 to 0.070 inches. The unit operates within a temperature range of -40°C to +125°C and carries an electrical rating of 3 A.

Edgeboard Connectors Feature Summary

• Vertical through-hole installation with wire wrap termination for secure board attachment
• Cantilever spring contact design ensures reliable mating force and signal integrity
• High-temperature DAP insulator construction maintains stability under thermal stress
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Automotive electronics modules operating in harsh thermal environments
• Communication infrastructure equipment with dense interconnect needs
• Medical device internal circuitry demanding stable signal transmission

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct pin count and termination style. Confirm that the target application PCB thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure wire wrap tools are compatible with the terminal dimensions before procurement.

Edgeboard Connectors Selection Notes

Select this model when a single-row, 42-position interface is required for vertical mounting. The 0.156-inch pitch accommodates standard board layouts while providing ample spacing. Consider the 3 A current rating for power distribution or signal lines. The high-temperature rating makes it suitable for applications exceeding standard commercial limits. Verify that the wire wrap termination method aligns with the manufacturing process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 837 Series, a line of high-temperature card edge connectors. The series offers various position counts and termination options to suit different density requirements. The 837-042 variant specifically addresses applications needing a higher channel count in a single row. The series is characterized by its robust DAP housing and reliable cantilever contact technology.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 837-042-541-107 and 837-042-544-108 variations with different suffixes indicating alternate packaging or minor feature changes. Cross-series replacements from other manufacturers require verification of pitch, height, and current ratings.
