M80-8281842

Overview

The M80-8281842 is a Datamate L-Tek series header connector manufactured by Harwin Inc. It features a dual in-line (DIL) configuration with 18 positions arranged in two rows of nine. The connector utilizes a 2.00mm pitch and is designed for surface mount technology (SMT) installation. It employs male pin contacts made of phosphor bronze with tin plating on the tail and gold plating on the mating interface. The housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0. Key electrical ratings include 2.2A current capacity and 800V voltage rating, operating within a temperature range of -55°C to 125°C.

Feature Summary

• Datamate L-Tek series design ensures high reliability and durability under harsh environmental conditions.
• Four-finger beryllium copper contact system provides secure connection integrity against vibration and shock.
• Shrouded four-wall housing design offers protection and alignment during mating.
• Surface mount termination facilitates automated assembly processes.

Applications

• Industrial control systems requiring robust board-to-board interconnects
• Automotive electronics subjected to high vibration and temperature extremes
• Medical devices demanding high reliability and compact form factors
• Telecommunications equipment needing stable signal transmission

Procurement Notes

Verify the specific suffix codes against the official Harwin datasheet to confirm exact plating thickness and packaging details. Ensure compatibility with SMT reflow profiles specified in the manufacturer's guidelines. Cross-reference the component marking with the physical sample to prevent counterfeit parts. Confirm that the selected variant matches the required current and voltage ratings for the target application environment.

Selection Notes

Select this component when a surface mount male header with a 2.00mm pitch is required for space-constrained designs. The 18-position DIL layout suits applications needing moderate channel counts without excessive board area usage. Consider the 800V rating if higher voltage isolation is necessary compared to standard low-voltage connectors. Evaluate the thermal stability of the PPS material for high-temperature soldering processes.

Part Context

This part belongs to the Datamate L-Tek family, known for its ruggedized performance in demanding sectors. Unlike standard connectors, it incorporates specialized contact geometries for enhanced retention. The M80-8281842 specifically addresses the need for reliable SMT mounting while maintaining the mechanical strength characteristic of the broader M80 series. It complements socket counterparts like the M80-850 series for complete interconnect solutions.

Replacement Considerations

Direct substitutes may include other Harwin Datamate headers with identical 2.00mm pitch and 18-pin SMT configuration. Verify mechanical footprint and pinout compatibility before substitution. Generic equivalents are not recommended due to the specific four-finger contact design and material specifications unique to the Datamate system.
