M80-8504442

Overview

The Harwin M80-8504442 is a Datamate L-Tek series double-row female receptacle connector designed for through-board mounting. It features 44 positions (22+22) with a 2mm pitch and straight vertical orientation. The contacts are gold-plated, supporting an 800V rating. Constructed from glass-filled polyamide insulation rated UL94 V-0, it operates within a -55°C to +125°C range. The connector utilizes 3mm PCB terminations and includes a locking mechanism for secure board-to-board or cable connections.

Feature Summary

• Double-row female receptacle design with shrouded housing for precise alignment
• Gold-plated contact surfaces ensuring reliable signal transmission
• Integrated locking mechanism for secure mating engagement
• High-temperature resistant polyamide insulation material

Applications

• Automotive electronic systems
• General purpose industrial interconnects
• Military equipment connections

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm exact plating thickness and packaging configuration. Ensure compatibility with mating male headers regarding stack height and pin count. Confirm that the through-hole termination style matches the target PCB fabrication capabilities and thermal profile requirements for soldering.

Selection Notes

Select this component when a high-density, double-row female interface is required for robust mechanical retention. The 2mm pitch allows for compact circuit board layouts while maintaining adequate spacing. Consider the 800V rating and wide temperature range for demanding environments. Verify that the 3mm tail length accommodates the available board clearance and solder mask definitions.

Part Context

This part belongs to the Datamate L-Tek family, known for its ruggedized performance in harsh environments. The L-Tek series distinguishes itself with a unique locking feature that prevents accidental disconnection. As a female receptacle, it pairs with corresponding male pins to form a complete interconnect system for power and signal distribution.

Replacement Considerations

Direct substitutes within the same series include M80-8501442 and M80-8502442, which share identical mechanical and electrical characteristics but differ in position count. Cross-series replacements require careful verification of pitch, row configuration, and locking mechanisms to ensure functional equivalence.
