M80-7900545

Overview

The M80-7900545 is a Datamate L-Tek vertical printed circuit board connector assembly manufactured by Harwin Inc. It features a 2mm pitch with female socket contacts designed for board-to-board or cable applications. The component utilizes beryllium copper contacts with gold plating to ensure reliable signal transmission in demanding environments. Rated for 120V, it supports solder termination and operates within a temperature range of -55°C to +125°C. The housing is constructed from black Polyphenylene Sulfide (PPS) material, providing mechanical stability and thermal resistance suitable for high-end industrial and military/aerospace usage.

Feature Summary

• Four-finger beryllium copper contact design for enhanced durability
• Vertical orientation with solder tail termination
• Gold-plated contacts for corrosion resistance
• High-temperature PPS insulation material

Applications

• High-end industrial control systems
• Military and aerospace electronic assemblies
• Board-to-board interconnects requiring robust reliability
• Cable-to-board connections in harsh environments

Procurement Notes

Verify the specific pin count and housing configuration against the official Harwin datasheet before procurement, as suffix variations may alter physical dimensions or contact arrangements. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure mating connectors are selected from the same Datamate L-Tek series to maintain interface compatibility and electrical integrity.

Selection Notes

Select this component when vertical mounting space is limited and high-cycle durability is required. The four-finger contact structure offers superior retention force compared to standard designs. Consider the 2mm pitch constraint for PCB trace routing density. Verify that the 120V rating aligns with the system's voltage requirements and that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the Datamate L-Tek family, known for its ruggedized performance in critical applications. The M80-7900545 specifically represents a vertical female assembly variant. It complements male header counterparts within the same 2mm pitch ecosystem, enabling secure interconnections in sectors where vibration and thermal stress are significant factors.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 2mm pitch, vertical form factor, and female contact type. Alternative solutions must be validated against the original mechanical footprint and electrical ratings.
