M20-7831046

Overview

The Harwin M20-7831046 is a 20-position, single-row female PCB receptacle connector from the M20 series. It features a 2.54 mm (0.1 inch) pitch and is designed for vertical through-hole mounting with solder tail terminations. The housing is constructed from black UL94V-0 polyamide (nylon) 6T material. Contacts are made of tin-plated phosphor bronze. The connector supports a current rating of 12 A and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Vertical board-to-board connection system utilizing single-row female socket design
• Through-hole mounting configuration with solder tail termination for secure PCB attachment
• High-temperature resistant black polyamide 6T housing meeting UL94V-0 flammability standards

Applications

• Industrial equipment control panels
• Data collection systems
• Mobile maintenance display units
• Portable test instrumentation

Procurement Notes

Verify the specific pin count and row configuration against project requirements, as datasheet references vary between single and double-row descriptions. Confirm that the vertical orientation and through-hole solder tails match the PCB layout constraints. Ensure the operating temperature range of -40°C to +105°C meets environmental specifications. Cross-reference the 12A current rating with actual load conditions to prevent thermal issues during operation.

Selection Notes

Select this component when a vertical, single-row female interface is required for board-to-board connections. The 2.54 mm pitch is standard for general-purpose interconnects. Consider the nylon 6T housing for applications requiring high thermal stability and flame resistance. Verify compatibility with mating male headers in the M20 series or equivalent 2.54 mm pitch systems.

Part Context

This part belongs to the Harwin M20 series, which provides 2.54 mm pitch connectors conforming to industry conventions for pin header and socket systems. The M20 series is engineered for industrial solutions, offering reliable performance in factory equipment and data acquisition environments. The M20-7831046 specifically represents the 20-position variant within this standardized product family.

Replacement Considerations

Compatible substitutes include other 20-position, 2.54 mm pitch, vertical through-hole female sockets with similar current ratings and housing materials. Ensure any replacement maintains the same contact plating and operating temperature range to guarantee mechanical and electrical compatibility.
